20 kinds of dead machine case records
Case 1: A compatible computer configured as MMX166 processor, T2P4 motherboard, 32MB memory, and 3.2GB hard drive, use the operating system for Windows98. When the power indicator is turned on, the power supply fan is also rotated normally, but the computer does not start, and there is no boot self-test screen. Analysis and treatment According to the user, the last use of the machine is April 26, and he has a white-character blue screen failure when he runs Word, and then the above phenomenon occurs again after turning off the power. I heard that this day on April 26. It is estimated that CiH destroys the motherboard BIOS chip and hard disk of this computer. The only solution is to rewrite the BIOS. This is processed by this: 1. Unplug the BIOS chip on the board, plug in another normal T2P4 motherboard's BIOS chip, and start the computer. At this time, you can only start from the floppy disk, which should include the BIOS upgrade program of the model motherboard (BIOS upgrade program can be found on the main drive disk), such as the BIOS upgrade program of Award is awdflash.exe. 2. Run awdflash.exe, follow the requirements of a BIOS file, after the backup is completed, use the damaged BIOS chip to normal, then continue the next step of AWDFLASH.EXE - write back the BIOS file that just backed up back into damaged chips The process of refreshing the BIOS is only a few seconds. At this step, the BIOS has been repaired. 3. The hard disk is also destroyed, and there is nothing important above, restores the disk, format it, and restores normal after installing Windows 98. The method of repairing the BIOS is the "hot swap method" that everyone often mentioned. This method requires an electric plug-in BIOS chip, there is a certain risk, but as long as the operator is daring, generally is safe (author) More than a dozen BIOS, which is repaired by this method, from there is no problem.). At the same time, "Hot Insert Law" does not require other devices (such as erasers, etc.), easy to operate, is not losing the preferred method under amateur conditions.
-------------------------------------------------- ------------------------------
Case 2: Fault Phenomenon A 586 compatible machine, configured as Intel 430TX motherboard, Pentium 100MHzcpu, 16MB memory, Trident 9680 graphics, segate 1080MB hard drive. There are two different situations after boot: 1 The screen has no display, "crash" phenomenon, knocking any keys have no response (display, host power indicator light), or hear any self-sounding and alarm; 2 sometimes normal Work, use the latest version of KV300 to clear viruses, discover the hard drive non-toxic, but the first case occurs if the shutdown or thermal start is started.
Analysis and treatment 1. Due to no display of the screen, first consider whether it is a display or graphics problem. I found a display of the same model, and the fault is still. Turn on the chassis and replace a good graphics card. After booting, it will be displayed. 2. Shutdown, restart, fault re-emergence. Also transfer the graphics card to other PCI slots, no improvements, the factors of the PCI slot are excluded. 3. Looking for a good ISA graphics card to start after inserting, the fault disappears. Re-heat start, the screen is no longer displayed. 4. Remove the graphics card, turn it back, and find the alarm sound of the graphics card failure when the host is self-test. Therefore, it is suspected to be related to memory. 5. Unplug the memory module, change the order, first install the original 3th and 4 memory strips, and then reboot, OK! The screen shows memory to 8MB (4MB per unit). Shutdown, install the first and second memory strips, boot, display 16MB, and the fault disappears. Find the original display and graphics card, plug the graphics card into the original PCI slot, everything is normal after boot. From the situation where the fault occurs, it is caused by the data when the data is loaded (primarily the first 64kb of RAM). From the memory strip, it is due to the unstable or quality of the first block, and an error occurs when the computer starts addressing. -------------------------------------------------- ------------------------------
Case 3: A fault phenomenon is configured as PII 350CPU, 64MB memory, ABIT BH6 motherboard, 8.4G hard disk compatible computer, a black screen failure appears when starting, and the computer issues an emergency alarm sound.
Analysis and treatment of the machine in 133X3.5 = 467 MHz, it has been more stable. When the above fault appeared at a time playing "Need for Speed 3", the system suddenly collapsed, and then it could no longer start. There is no big problem with the power supply, motherboard, and CPU. The display is dead and the alarm is displayed on the display, and the problem is issued from a hardware between the self-test CPU to the graphics card. There is only memory and display cards that meet the above conditions. Before the PC133 specification is not promoted, the computer running under the frequency of 133MHz, its memory bar (PC100), AGP display card (working in 133x2 / 3 = 88.7MHz) is extremely overclocking, compared to the memory module is easier problem. With a 64M memory bar of LGS 7K, change the original hit, the computer started smoothly. Now the quality of the PC100 memory strips on the market is also uneven. Inferior PC 100 SDRAM memory strips are barely rooted under 100MHz, waiting to be 124MHz, 133MHz These high outer frequency is more than half of the problem. This example is the case, and the miscellaneous memory module under 133MHz is finally burned because of excessive fever.
-------------------------------------------------- ------------------------------
Case 4: Fault phenomenon is configured as Celeron 366CPU, ASUS P3B-F motherboard, ASUS V3400 graphics card, 6.4GB hard disk, 64MB memory, and ordinary sound card compatible computer, use in overclocking, normal procedures, but in After playing the MP3 system crash.
Analysis and treatment crash occurred after playing MP3 for a period of time, so it was initially suspected to be caused by MP3 playback software conflicts, but after replacing other MP3 playback software, the fault is still not excluded. At the same time, the discovery of the down-converted frequency is still fault, and it is eliminated that overclocking can cause crash. Later, carefully check the hardware related to playing MP3, found that the temperature on the sound card chip is very high, almost "roasted eggs", after adding a cooling fan on the sound card chip, the fault disappears. Case 5: Fault Phenomenon Installing Windows98 under Windows95 System, install the dialog box at the end: "Press the Start button immediately, the computer will immediately restart, otherwise the computer will automatically restart after 15 seconds." After starting, the blue light flashes, and the crash.
Analysis and treatment preliminary analysis may be caused by certain hardware device conflicts. Unplug the other expansion card or device except the graphics card, and then install Windows98. If the above situation still occurs, press the F5 key when booting, start Windows 98 with the security mode, then extract the graphics driver to the hard disk. In Settings -> Control Panel -> System -> Device Management, the auto-set graphics card and monitor driver, after installing the driver with the card, the disc is installed from the optical drive Remove, restart your computer. After Windows 98 is started, start prompting to discover new hardware devices, install the software, select the installation display card driver from the disk, and then install the original graphics driver. Why do you want to remove the disc installation? If you don't get it, Windows98 will be stubbornly installed on the driver it identifies, do not give you a chance to choose, so remove the disc and give it a suction.
-------------------------------------------------- ------------------------------
Case 6: Fault phenomenon suddenly crafted when using a Windows98 operating system. After restarting, double-click "My Computer", or crash; press "WIN R", crash; click "Address", crash; start the resource manager, crash; right click any place, crash; click on Quick Launch Created Word icon, crash ...
Analysis and treatment first suspected that the system was damaged, and the Windows 98 was reloaded, and various drivers were installed. Restart, continue to crash ... Under the anger, "FDISK / MBR", "Format C:", "Format D:" SYS C: "a few operations, install the driver of the optical drive (Toshiba 16x), re-re- Install the Windows 98 operating system, all restoration, no crash phenomenon. Subsequently, one brain puts all the drivers, including motherboards, IDE, graphics card, sound card, etc., double-click "My Computer" after restarting, and crash! I Not online, two two months did not buy a D version of the disc, anti-virus software is just upgraded, what is the reason? First reset to safety mode! After self-test, then "Verifying DMA Pool Data "," Starting Windows 98 ... ", a late step, did not press F8, but this is not tight, delayed! DMA! It seems to have this option when you installed the IDE driver, and I was carried back by me all the way. Quick, even twice "Ctrl Alt Del" (no dead machine, really fortunate), press F5 to enter Safe Mode, first remove the IDE driver again, then press two "Ctrl Ten Alt Ten Del", OK, normal. Look at the driver, there is a "PIO", "DMA" option, and I have been a Pio, which is different. So Windows 98 doesn't know, of course, death, it can be seen. : The driver determines the working conditions of the hardware. It is the big Dongdong, must be carefully optimistic about every option, do every-step. ---------------------------------------------------------------- -------------------------------------------------- ----------------
Case 7: Fault phenomenon a Lenovo computer (P166 / 16MB) crash when playing games, first use KV300 (V ) inspection, no virus, the DOS startup file in the Windows 95's Command Sub-directory override the same name file After startup, first appear in the Win95 launch screen and appear immediately: Drivespace Alarm # 15 a Program Has Corrocted Memory Belonging to Drivespace Further Disk Activity Could Result In The Loss OR
Some or all of the data on your driver. Therefore, driverspace has halted your computer. for more information, consult Your online help or document. Then crash.
Analysis and handling this DRIVESPACE file used by Windows 95 may be caused by viruses or other reasons (including abnormal shutdown, system instability, etc.). You can press the F8 key when booting, the startup menu appears, select the previous version of DOS, enter DOS6.x (also available DOS6.x boot floppy drive with optical drive) to perform the Windows 95 Setup on DOS6.X, Select "Restore the destroyed file" to recover the file. If you are reinstalled, playing games or crazy, may be caused by the quality of the game CD, the optical drive error correction ability, insufficient memory, requires EMM386 software, etc. -------------------------------------------------- ------------------------------
Case 8: Fault Phenomenon When the computer is started, the "ERROR Loading Operation System" error message is displayed on the screen.
Analysis and handling this error message means "loading the operating system error", this information is prompted when reading the partition boot sector error. Possible reasons are: 1. The partition start address indicated by the partition table is incorrect. For example, the third byte (start sector number) of the partition entry is changed from 1 to 0, that is, the start address of the partition is indicating the magnetic head, specifies the 0 shoulder area on the track (this bit is a physical address. The sector number should be started by 1), and the INT13H read disk failed to report this fault. 2. The track mark and sector ID of the track where the partition boot sector is located, and the specified sector is not found. 3. Drive read circuit fault. This situation is relatively rare, most is a random read error, because the system boot can be made here, at least one of the main guiding sectors have been correctly read. When this error is encountered, the disk doctor NDD can be used to directly recover the partition table.
Case Nine: Fault Phenomenon A computer uses Quantum unstead 1.2G hard drive. On a certain day, when playing WIN98's "empty as a Solitaire" game, the system prompts "Reading the Dial" and then the machine, the heat start is displayed: Disk boot failure. Insert System Disk Press Enter. After booting with a floppy disk, turn the C drive, prompt: Invalid Drive Specfication. Using SYS C: also failed, using the fdisk command, get a prompt and information: No Fixed Disks Present. Set the CMOS parameter to the default value and set the hard disk to automatic detection. Restart after saving, after memory detection OK, display: Detecting HD Primary Slave ... Quantum Bigfoot1280A. The prompt in the System Configuration Information box is: Primaster Disk: None. Repeat the above operations everything. After the hard disk is removed from the normal computer, the defendant did not check the hard drive.
Analysis and treatment is really hard drive! It may be saved using low-level formatting, but I hope it is not big. Quantum's hard drive has a special DM software, you can ask your friends to download or copy a Quantteng DM disk from the local Quantum agent, and do the final trial.
-------------------------------------------------- ------------------------------
Case 10: Fault Phenomenon A computer uses Celeron 300a, AL007's PCI sound card, and overclocking the computer over 100MHz, the crash is frequent. Check the temperature of the CPU in the BIOS, still remains around 30 degrees, nor did any viruses. Analysis and treatment crash is likely to be related to overclocking. The overclocking ability of Celeron 300a does not make people feel very relieved, and the motherboard cannot support 100MHz extravreads very certain. Since overclocking does not completely depending on the temperature of the CPU, it may also be dead at normal temperatures. Resolve this problem.
-------------------------------------------------- ------------------------------
Case 11: Fault Phenomenon A computer is configured as ASUS TX97-Le motherboard, Cyrix200mx processor, 16MB SDRAM, TRIDENT9680 graphics card, Sky 98 sound card, TE2000B network card, diamond 2.1GB hard drive. The boot can be started normally, and the mouse is moved after the end is started or some simple operation is dead. If you turn it over again or press the reset key, the machine's operation can return to normal, no longer dead. However, if the downtime is more than half an hour, the power-on fault will appear again.
Analysis and handling the location of the machine is a Internet cafe, there are ten machines that are equally configured, and three of them appear, and the rest of the seven are all normal. The failure of the machine is less common. It should be judged that there is a problem with some of the equipment reset circuit in the machine, and it cannot be reset once. But what equipment is it? Without judgment, it has to be tried to be used with a replacement method. Since it takes half an hour after the replacement takes half an hour, it can be seen, so this replacement experiment is quite a discount. The result of the replacement is that the sound card is faulty: after replacing the sound card with a fault and the fail-free machine, boot over half an hour, and the failover is transferred to the machine that is not faulty.
-------------------------------------------------- ------------------------------
Case 12: Fault phenomenon A 586 compatible machine adopts 430VX compatible motherboard, 8MB memory, 2032 graphics card, Cyrix 6x86mx PR166 processor, 850MB Segate hard drive, Samsung 8-speed optical drive. In recent time, students often crafted often when they were running, and 3-5 times per hour, DOS was working properly.
Analysis and processing first suspect is a memory problem (although the system self-test memory is passed, and there is no error). Open the host, replacement of memory, the fault is still concerned, and after the panel contact is poor, the display card is pulled down, the slot is turned on, or there is no rule, and finally is the problem of the motherboard or CPU, replace other machines The same kind of CPU is faulty or cannot be excluded. Obviously there is only the motherboard failure, because the machine has passed the warranty period, holding the motherboard jumper by 60x2.5 = 150 (Cyrix 6x86 166 actual operating frequency), after the screen is displayed For 150, everything is normal after operating hours, continues to run for more than 2 months, no crazy phenomenon. The motherboard fault should be said to be a relatively large fault, and there is no considerable expertise and dedicated equipment. However, this example is special, as long as the motherboard can move, it may be a try. As the overclocking use will increase the burden of the entire system, the reduction rate will reduce the system burden, which will solve some small faults. Of course, this is based on the performance of the sacrificial system.
Case 13: A fault phenomenon is configured as a compatible computer of Celeron 333, 64MB memory, BX motherboard, 6.4GB hard disk, the operating system is Chinese Windows 98. When the power indicator is turned on, the power supply fan is also rotated normally, but the computer does not start, and there is no boot self-test screen. Analysis and treatment of the machine has been operating normally, and there is no signs of CIH virus. However, the user before the failure has removed the CPU and a fan is applied to the CPU heat sink. Since the user has moved computer hardware, it will find a focus on hardware failure. 1. Unveiling the chassis cover, found that the power is turned off, the hard disk, the optical drive light is on, and the CPU fan (on the motherboard CPU fan interface) is also normal, tested with the multimeter test, the power supply ± 12V, ± 5V output is normal, The problem of the power supply can be excluded. 2. Remove the CPU, memory, graphics card and other components of the machine to be reinstalled once, ensuring that the installation is in place, and the contact is good. Start again, the fault is still, eliminating the problem of poor contact. 3. Remove the sound card, optical drive, hard disk, etc., leaving only CPUs, memory strips, graphics cards on the motherboard, and makes up a minimization system. At this time, the startup screen does not appear. To this step, you can determine the cause of the failure on the CPU, memory or motherboard. 4. In theory, when there is a problem, there should be alarm sound when starting, and only the motherboard, the CPU is damaged when it is damaged. I found a normal classification 300A to stand down the original Celeron 333. When the self-test screen is turned on, it is determined that the original CPU is damaged. 5. Carefully observe the CPU and found a deep scratch on the two pins of the CPU Golden Finger, and the two feet have been cut off. Asked the user, saying that the second CPU fan is installed, and the knife of the screwdriver is hit on the CPU. So very carefully use the soldering iron to weld these two cut pins, and then insert this CPU back to the original main board after completion. This time, it can finally start, and the problem is solved.
-------------------------------------------------- ------------------------------
Case 14: Fault Phenomenon is configured as a compatible computer of Sai Yang 366 processor, MSI 6199NA motherboard, ASUS V3800 (TNT2 Standard Edition) graphics card, 32MB memory and IBM 15.2GB hard disk, operating system is Windows98. A black screen crash occurred while exiting after each running 3D game, but no matter how long it is used in the game, it will not have a crash.
Analysis and treatment 1. Because the machine uses the Celeron 366 to 500, the first after the crash will be suspected to be overclocking. However, it is found that the failure is still in the absence of 366. 2. Then doubt whether it is because the memory is too small, not enough to run 3D games (Windows98 requires memory to 48MB, but after increasing memory, it also gains a negative result. 3. There is only two aspects: Hardware The quality of the quality is good and hardware. After the user replaces the latest driver (not with the driver of the card), the fault is eliminated. Later, in some introduction, "use low The ASUS V3800 series graphics cards of the version driver will occur in the failure of some games, "," more confirmed the cause of the fault, but the use of the high version of the driver will not malfunction. This is a typical driver caused a crash Case.
-------------------------------------------------- ------------------------------
Case 15: Fault phenomenon after the application software Turbo C2.0 installed, "Starting MS-DOS" is dead when starting. Analysis and treatment Estimate Turbo C2.0 software in the CD toxic. After starting using the system disk, enter the hard disk to see the length of the file of Command.com is 0 bytes, which is clearly the virus. Re-copy this file from the floppy disk, the hard disk can be activated.
-------------------------------------------------- ------------------------------
Case Sixteen: Fault Phenomenon has written a full table document in Word97, with a total of 30 pages. Once opened it, Word stopped when automatic page 8, so that I can't edit it, I don't know how to deal with it.
Analysis and handling this situation is usually something in the document containing some Word can't recognize characters or macro, you can try the following method: After opening this document, there is no page 8 when Word has not paised to page 8 immediately This document is saved as a low version of Word format, such as "Word 6.0 / 95 (*. DOC)" or "Word for Windows 5.0 (*. Doc) from" Save As "dialog box. ", So that you can save the style of the table or the character or macro screen that Word can't be recognized. Finally, in Word97, this low version of Word document opens re-editing. In fact, other similar issues that appear in Word97 can be tried to solve this altime.
Case Seven Fault Phenomenon When running a large application in Windows95, the hard disk light is crazy, prompts "Loading the operating system error 'immediately crasted.
Analysis and handling this related to virtual memory. If the memory is smaller, the large-scale application is running, there is a large virtual memory. If the virtual memory is not enough, the system will crash. It is recommended to delete some temporary files to spattern for virtual memory.
-------------------------------------------------- ------------------------------
Case 18: Fault phenomenon After the Norton 3.0 tool fails, restart your computer, and the result is that the system sometimes prompts "You can safely turn off the computer" shutdown screen, you cannot enter the Windows interface. Sometimes, although it is able to enter, the system prompts "Registry Error, Cannot Backup Registry" or "There is not enough space backup registry", and the desktop font settings, wallpaper settings, etc., the desktop display font is very small to see unclear . Reinstall Windows98, the fault is still, check the no-virus, no hard drive, is the registry repair tool such as Reglean and cannot be repaired, and it feels helpless.
Analysis and handling an accidental open registry, discovering a HKEY-DYN-DATA project tree, prompting the project error, and then discovering that the content is empty. So from another machine, select the item, select the export registry, and become a 5MB REG file, compress this file with the compression software, and then decompress the data into the registry after the shuttle is decompressed. Restart the machine and the system will return to normal. The HKEY-DYN-DATA project tree is stored in Windows95 / 98 user configuration information. Once lost, the system is errors, but if you can lead the entry from other machines, you may be resolved.
-------------------------------------------------- ------------------------------ Case 19: Fault phenomenon I have an IBM 300GL PC, randomly installed Windows 95 OSR2 Operating system, after a period of time, the system shutdown is abnormal, and it is manifested as "Start" -> "Off System", select "Turn off the computer" or "Restart the computer", the screen appears "is off the system , Please wait ... " what do I do?
Analysis and handling Windows95 When shutting down, you need to close various applications, turn off the open file, turn off the network connection, write back the hard disk of the hard disk buffer back, and finally turn off the power. After the prompt "is turning off, please wait ...", you can try to wait for a long time. If the system can automatically shut down after segmentation, it is generally a network problem. Windows98 has a correction for the network's driver, which can solve the clockwise phenomenon when it is upgraded to Windows. If your machine is not connected at all, if the virus infection is excluded, it may be a problem with the Windows 95 virtual memory swap file. The problem can be solved by modifying the settings of the virtual memory in the Control Panel -> System. If the problem continues to exist, it is very unfortunate, you need to exist, so very unfortunate, you need to reinstall Windows95.
-------------------------------------------------- ------------------------------
Case 20: Fault phenomenon a new configuration compatible machine is always three, five minutes left and right, and the picture is not moving, the optical drive stops the disk.
Analysis and handling the information given from the above, the problem cannot be judged. The S3 Savage graphics card used by the computer and the 64MB BX private memory and Gigabyte BXC motherboard are not conflict. After the exclusion of hardware appears, the following aspects are checked. Sound Card: 8900 and other early models of products are very compatible with Windows 95/98, if there is an audio signal in the game, there are ten eight nine. CD game itself: Some pirated CD games are likely to lose or modify some file names (such as Game-1.dat change to Game_1.dat), if it is the game run (not When the game is started), the data is required, and the crash is also taken. System: Testing operating system, especially Windows 95/98, often easily interrupting error triggering phenomenon when dealing with large quantities of data. If the player tries to play the CD game, it will inevitably lead to steep increasing system overhead, and finally crash. After the final examination, the problem is appearing on the disc (if the inspection is not resolved according to the above case, the hardware plug and wiring should be checked.
-------------------------------------------------- ------------------------------
Conclusion: In fact, the factors of computer crane are hidden in all corners of your computer, from hardware, system programs, application software to operating habits, etc., at any time when you are busy, I will climb out to make your hands. . So, when your computer loses reason, let's take a look at the twenty cranes that we provide for you and its analysis and solution. Maybe it will find a shortcut in a short time, truly let you get rid of the crash. The trouble of nightmare.
Seventy-seventh, computer failure emergency treatment friends will inevitably encounter many sudden failures in the process of using the computer, which may be caused by software, or otherwise Factors ... So, how do these primary computer users should deal with these events, please see below: encountering power outages: display, host, speaker, etc. will "forgively turn off" in a moment. Phenomenon analysis: This is caused by "power outage". Voltage fluctuations generated by power outages will impact computer hardware chips, circuits, resistors, and the like. Once you have power outage, you are on the disk read and write operation, it is possible to produce a bad track, or when you write a document, the data will be lost ... should be the policy: choose a brand power supply when the computer is equipped. Maximum extent to reduce voltage fluctuations on hardware from the power supply. After powering up, turn off all power supplies to prevent the display and part of the ATX power at the same time when the next time, which will cause adverse damage to the hardware. When you use a Word Editor's document, use the Word's auto save function. If the power outage is in an instant you act on the disk, it is recommended that you start the disk detection at startup next time, detecting a bad deed. Once the bad track is found, use Norton, Pqmagic and other tool software to fix or block the bad track. In addition, if you have an economical license, it is recommended to select a UPS to provide a computer-off protection for a while. Automatic shutdown: The computer suddenly shuts down the system or restart system during normal operation. Analysis: Today's motherboard has temperature monitoring function on the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard automatically cuts off the power to protect the relevant hardware. On the other hand, power management and virus software in the system will also cause this phenomenon. The strategy should be said: If the above sudden shutdown, if it has been happening, it will confirm whether the cooling of the CPU is normal. Whether the fan blades are working properly, then enter the BIOS option to see the speed of the fan and the working temperature of the CPU. It is found that the problem of the fan is discovered, and the dust-free maintenance or replacement of the fan is better than the fan. If the reasons for hardware is excluded, enter the system, cover the installation of power management from the "kiss to death" installation CD, and then thoroughly kill viruses. When these factors are excluded, the cause of the fault may be power aging or damage, which can be confirmed by replacing the power supply method. If the power supply is broken, it will not continue to use, will burn hard. Systematic machine: The desktop is locked, the mouse cannot be moved, and the heat start (Alt Ctrl DEL) is not working. There is also a blue screen phenomenon. Phenomenon: "Kissing the dead" system itself BUG and compatibility problems between software are the cause of the fault, or the user has run too many big programs at the same time, causing the process to block, trigger a machine. Countermeasures: Boarding 2, true and false, the easiest way to distinguish between the secondary keyboard is the Numlock key of the keypad area to observe that its indicator changes. Yes, then false; contrary, true. If you can press Alt Ctrl DEL to select the program name after you select the program name, you click the item that does not respond, click the end task. Really, only cold start. For blue screen, after pressing the ESC button, select Restart, press the reset key on the chassis panel. For compatibility issues, you can solve from the uninstall "problem" software and update the motherboard BIOS and related motherboard drivers.
Viral attacks: system running slowly, computation, illegal operation, hard disk light, often blue screen, and inexplicable system prompt ... Phenomenon analysis: Virus is essentially a malicious computer program code, virus passed a lot of self Copy, while hust in the system, occupying system resources, seriously damage software and hardware, such as CIH, hard disk lock, etc. Countermeasures: Tao is one foot, the devil is one foot, and the grati of the virus is anti-virus software. Once you suspect your own machine, please restart the system to DOS, run the genuine anti-virus software (DOS version) can kill the virus that can't kill "kiss to death"; then start to the system desktop, run anti-virus The software's Windows version is anti-virus. On the other hand, since some files are destroyed when the virus occurs; we will back up important files to other drives outside the C drive before the virus attacks, and set the properties of the data file to read-only. At the same time, everyone must update the anti-virus software virus bank, less pirated disc, friends who have been online, don't download unknown email. System Fault Phenomenon: Can't enter the system, typically behave as boot self-test, stop at the start screen, or display: The Disk is Error, etc. has many phenomena. Phenomenon analysis: This is a system failure, which can be caused by many reasons, and more common is that the system file is modified, destroyed, or loaded with an abnormal command line. In addition, the fault of the hard disk is also one of the reasons. Countermeasures: First, try to enter the security mode, press the F8 key to boot, select the third item in the startup menu: Safe Model. After entering the security mode, you can find faults through the device manager and system file inspector. If you have a "!", You can find out whether it is DEL or set interrupt. You can also reload the driver, and the system file is damaged can be recovered from the installation file (it is recommended to copy the Windows installation disk in the hard disk in advance). If even the security mode cannot be entered, start to DOS through the launched disc or a floppy disk, and use DIR to check whether the system files in the C drive are intact, if necessary, Sys C:, Restore the relevant basic system files. If there is no file in the C drive, only the system is completely reloaded.
Drive loss phenomenon: 16 color display when booting, display "XXX" device is occupied when the audio file is placed. Phenomenon: After excluding the cause of the virus, this phenomenon occurs in the old man who has used N month, or the user is newly mounted by components in the host, (such as graphics card and PCI card), may cause the hardware to contact Poor, leading to the system substantially not completely detected the relevant hardware. Countermeasures: Reinstall the driver of the graphics card, and check if the relevant accessories and the motherboard are completely contacted: That is, then connect the speaker and display connection with it. If necessary, you can replace the slot location of the PCI card, avoiding the resource conflict with the graphics card.
Power-on black screen: boot black screen, no display, may have alarm. Phenomenon analysis: poor contact between hardware, or hardware failure, related hardware involves memory, graphics card, CPU, motherboard, power supply, etc. The computer's boot should be powered by power supply, and then guide the self-test by the BIOS of the motherboard, followed by CPU, memory, graphics card, etc. This process is reflected in the screen called self-test, first pass the information of the graphics card BIOS, then the motherboard information, then memory, hard disk, optical drive, etc. If this is a problem in the middle, the computer can't start normally, and even black screens. Standby: First confirm whether the external connection and the internal connection are smooth. External wiring has a display, host power supply, etc. There is a connection between the host power supply and the host power interface (sometimes contact with the host). The more common reason is: the graphics card, memory due to overall use time, with dust in the air, causing the oxide layer on the gold finger, resulting in poor contact. In this regard, with a moderate alcohol with a moderate alcohol and wipe the golden finger and put it back. In addition, the CPU is observed whether the CPU is working properly, and the heat sink is touched by the hand, and there is a temperature. There is a temperature, the possibility of the CPU is broken. No temperature will sort out the CPU socket to ensure that the contact is in place. After this, there is no temperature, and you can upgrade it: (In addition to the above method, there is also a way to kill: Clear the BIOS setting or replace the CMOS battery for the BIOS. When these methods have tried And all failures, you can summon the prawns and brothers. The geeks are the phenomenon: I heard the geeks or smell the odor. Phenomenon analysis: Ring, may be due to the bad tray causes the hard disk (Gger harsh Sound); it is also possible to be a hard disk. The optical drive screw does not have a tightness, which causes the chassis to resonance. The odor, the odor, the nose. Coping: First turn the power. If it is a weird, turn the chassis panel First, check, if it is a bad road, fix it or mask. For odor, you should be careful. At this time, use your nose to hear, find the part of the odor, then remove the computer company to handle, in this middle, Everyone must defend their consumer rights. (No presupposition - the change of this change, the repair of the repair.) This must not have to be! Because the author's Onda open is a power-off Not as if (slow N second) gives the live-action burn drive the chip, then, if you find the money to find JS, there is no way. (So everyone smelling the odor, immediately discharging the power, then looking for the reason, but the display Don't open it, you can only be repaired by professional staff, but there is high voltage electricity, don't play your own life.
Seventy-eight, four lost CD-ROM frequently resolved 1. Due to hardware changes, the optical drive has not been found to have a friend's motherboard damage, and replace it to the dealer, and found that the original model motherboard has already stopped production, I have to add money. Changed another. After changing the motherboard, of course, it is necessary to reload the drive. After installing the graphics card sound card, I found that the optical drive cannot be found anyway. Reintenect Intel's INF program (chip recognition) and IAA (hard disk acceleration) program are still useless. Workaround: Click "Add New Hardware" in Control Panel, and let the system automatically find new hardware. After a few minutes, you will find "lost" "disc drive" again. 2. Because the BIOS setting causes the optical drive to lose a brand machine, it does not match the optical drive. After installing a new optical drive, the operating system cannot be found in the operating system. Workaround: Enter the BIOS, check the IDE settings, and find that all other are set to NONE except that Primery Master is displayed. Replace the Secondry Master to Auto and save the settings. Successfully found the optical drive. Although different machine BIOS has different, it has the settings of the IDE device. As long as the IDE-related parameters can be set correctly, they can find the optical drive smoothly.
3. The jumper choice of the optical drive is not
The rear of the optical drive usually has three jumpers: Master (primer), slave (slave), CS (Cable Select, cable selection). If the optical drive and the hard disk share an IDE data cable, the optical drive jumper is usually selected as slave, and the hard disk is set to Master. If the optical drive is a stand-alone IDE line, you can jump into the master. But I have encountered a rare fault. Whether it is the main disc or from the plate, I finally jumped into CS, and the optical drive appeared. So if you don't do it, try the CS jumper.
4. Due to unexpected system information loss (such as power outage, viruses, etc.)
It is the case that the beginning said. Workaround: Delete "IDE Controller" and primary IDE and from the IDE device (note order), let the system re-look for the device. Sometimes the IDE driver is installed when there is a dedicated driver of manufacturers such as Intel or Via, and use the "standard IDE driver" comes with the system.
In fact, there are many reasons why light-driven findings, such as the IDE data line break, the main board IDE interface is damaged, the cavalry itself is damaged, but due to the relatively simple processing method (replacing the corresponding device), this article will not deenever .
Seventy-nine, taking the "illegal operation" users often encounter "illegal operation" failures during the use of the computer, which can not only be caused by software and hardware, but also caused by viruses. Below, we combine the reasons for "illegal operation" and its solutions.
By the imperfection of the software itself
Typical examples: Photoshop graphics software is easy to generate "illegal operation" failures at runtime.
Workaround: Upgrade the software to a high version or upgrade patch. During running graphics software, users should reduce other programs to take up memory, and users can upgrade the graphics, sound cards, or displays.
Residual "zombie" and glacial Trojan from the virus
Typical example: .dll file failed.
Solution: Some viruses will change some files during the attack, once some important files are changed, the computer will hardly work. In this case, the user can use a clean boot disk to start the system, using anti-virus software to clear the virus, and use the corresponding software recovery system. Or first terminate the Ice Trojan in the memory, enter the registry to remove the key value of "key_local_mac hine / software / run" and "runservices"; "hkey_classes_root / xtfileshellopenco-mmand" key value Change to "C / Windwos / Note-Pad.exe% 1"; restart to DOS, then delete kernel32.exe and sys-cost .exe in the hard disk C / Windows / System. A typical example of damage or loss of system files: The Rundll32 program is invalid, and will be closed.
Solution: When pressing the "Detail" button, if the "Rundll32 Caused A General Protection Fault In module mmsystem.dll ...." is displayed, the reason is probably the user's System.ini file in [boot]. In the paragraph, the "Drivers = MMSystem.dll" command line is missing, and the user can solve the problem as long as it adds this command.
Caused by the incompatibility between the software
Typical examples: "Illegal Operations" caused by KVW3000 under Windows 98.
Solution: Many virus software do not follow Windows 9X "Memory Management" during operation, resulting in "illegal operation". Solving such problems, users can upgrade the sweeping software, and can also load the Windows 9X memory management program EMM386.exe for resolution.
Unreasonable caused by cache settings
Typical example: The buffer space is insufficient.
Solution: Win386.SWP can use a part of the hard disk space as a memory usage (set up the 2x size of physical memory), idle the programs in the memory, put it on the hard disk, and wait for the CPU to use these programs, Read it from the Win386.swp of the hard disk. In Windows 98, use virtual device disk cache Vcache or resolve such questions.
Resource lack of system resources
Typical examples: "illegal operation" caused by printing or saving.
Workaround: Upgrade memory, increase the cache, remove some unnecessary software. It is best to run a large software after starting the system. Users can also add a memory management expert software.
Overheat by the system and its system components
Typical example: SDRAM overheat failure.
Solution: Select a good heat sink and heat dissipation fan, the fan speed is high, the heat dissipation area of the heat sink is large, the heat sink material is conducive to heat dissipation, and the contact area of the heat dissipation member is large.
By hardware quality is not good
Typical example: "illegal operation" of SDRAM quality is unstable.
Workaround: First set the memory parameters in the BIOS, such as the value of SDRAM CAS LATENCY, set to CL = 3.
Caused by hardware I / O conflict compatibility
Typical example: The conflict of the NIC.
Workaround: Delete the "!" Device in device management, let the system re-identify the hardware and install the driver.
"Illegal operation" caused by hardware overclocking
Typical examples: CPU and SDRAM overclocking.
Solution: The harm of heat dissipation minimizes, controls the temperature of the CPU and SDRAM.
* * * * *
Avoid "illegal operation" small knowledge
★ Strengthen maintenance, dustproof, dustproof, avoid high temperature, high humidity; regular dust removal, dehumidification maintenance;
★ See fault, do not blindly handle, avoid other faults; ★ Do a good job, avoid the harm of static electricity;
★ Pay attention to prevent Trojan ice river, often update the anti-virus software;
★ Keep the stability of the chassis and avoid unnecessary vibrations to prevent the impact of hard objects;
★ Keep the hard disk's data neat, regularly run management software, such as disk scan, system file inspector, disk fragmentation, and backup program.
How to solve the problem of "illegal operation"? (Illegal operation solving examples)
We often see such an error prompt, "The application executes illegal operations, the program will be closed", and then the open program will be automatically turned off. How to avoid this problem? Although we can't guarantee the "illegal operation", if these tips often appear, you need to find the cause of the problem, and find a solution. If such problems often appear, especially when they appear in the same environment, the application may have a bug. When you appear next time, click the "Details" button in the prompt dialog. You can see the following message: "Excel has an invalid default page at 0137: 60067585 of the FMIO.DLL module, which is usually very useful. If the program provider knows this bug, these messages will help solve this problem. Browse the provider's webpage and find the related keywords or error numbers, and you will find a solution to this bug. If you have an "illegal operation" in multiple programs, or if you don't solve this problem even if you find a provider webpage, it is possible to be a problem with some drivers. The printer driver often causes an error in other applications. You can try to use a more versatile driver. For example, most laser printers are compatible with HP LaserJet SeriesII or HP LaserJet III driver. These drivers have been widely used, and may solve the problems you have encountered. The problem with the display card driver is more uncertain, it is possible that your graphics card only supports 640 × 480 resolution, even if Super VGA is also subject to this limit. Sometimes a display card chip can only use a specific driver, such as the S3 series, then you need to know which one installed display card is to select the appropriate driver.
Windows98, Windows2000, Windows XP Blue Screen Fault Research & Solution
There is a blue screen crash when the hard disk has a bad sector or has not been organized and the fragmentation is too long. This taste is not good, this blue "lightning" is often "flashing" when you work or look forward to the results of the god, this time, if you use the CTR Alt DEL key to force the program, you have to restart, hard drive The more the fragments are, the worse the blue screen, the worse, form a vicious circle. The day before, I've covered the blue screen, and I'm looking at the relevant forum. I also searched some articles. I feel that my understanding is very beautiful, causing a lot of reasons for the blue screen, there is hardware, there is software, and there are Other unusual factors, the solution is also more solutions. In view of this, this topic surrounds the "blue screen" from the cause, to Windows98 or 2000 specific soft, hard phenomenon, prevention, and recommend some tools. I hope that you should read it according to your own machine? Quot; the right medicine ", overcome the blue screen!
Blue screen reasons and countermeasures Overview:
The "Blue Screen" hardware reasons and solve the case where the blue screen is often encountered during the use of the computer. When "Blue Screen" appears, what we first think of is not hardware, yes, "Blue Screen" phenomenon is more than memory size, CPU frequency, optical drive, hard disk fragmentation, etc. ...
"Blue Screen" software reasons and solve the software closely contact with hardware, sometimes the software is "blue screen" phenomenon "work can't be", loaded too many programs, registration form, soft and wrong, driver If you have any questions, it is not easy to detect relative to hardware. You can pay more ......... Windows 2000 "Blue Screen" Analysis and Solution The Windows2000 is theoretically known as the never crash, but actual application In the process, it may not be expired, and the blue screen for Windows2000 is based on the above summary, and we are divided into two aspects:
The Blue Screen Crafts in Windows 2000 Analysis The "Blue Screen" (BSOD) and NT4 previous "Blue Screen" messages are completely different. The biggest difference is that the BSOD in the NT contains only one universal stop message type (that is, the actual error code), but the Win2000's BSOD contains two message types: stop messages and hardware messages. The stop message refers to the error message generated when Win2000's kernel finds a software error that it is not able to recover, it is divided into: General Stop message, install stop message, executable program installation stop message, software trap stop message four types ......
Windows 2000 Blue Screen Stop STOP STOP to "symptoms", in theory, pure 32-bit Windows 2000 does not have crash, but this is just theoretical. Causes of virus or hardware and hardware driver do not match the cause of Windows2000 crash, "STOP" information will be a good way to analyze the "blue screen".
Eighty, 19 active error-in-one computer startup phenomenon analysis launched the computer, if the problem is found, it will actively report. There are mainly below the following information: (1) Bad CMOS Battery Description: The CMOS battery power in the host is insufficient.

(19) Real Time Clock Error Description: The clock setting is incorrect. 16. Lack of troubleshooting methods caused by a Command.com file. What should I do when "Bad or Missing Command Interpreter" is "information" information? " Since the operating system is turned on, you need to boot two implied system files (IO.SYS, MSDOS.SYS) and Command.com files, thereby completing the launch of the machine. The above problem occurs is due to the lack of command.com files in the boot disk. The solution is to copy a command.com file to the hard disk, the fault disappears. Change a good system disk boot machine (you must match the system version on your hard drive); use the copy command of the system disk, format is: Copy Command.com C: 17. Troubleshooting caused by hard disk boot recording.
What should I do when "Disk Boot Failure, INSERT SystemDisk" (hard disk boot logging, insert system disk) information? If such information appears, it indicates that the system boot area is damaged or has been invaded by viruses. At this time, the method of comparing insurance is to start the system floppy disk, using the format command on the system floppy disk (format: Format C: / s / U), to replicate the drive record of the hard disk, but you have to pay attention, this command also swept the information on the C disk. 18. There is a lack of faults and rulers caused by two implicit files.
"Non - systemdisk or disk error. Replace andStrike Any Key When Ready. (What should I do if I have a floppy disk, when all ready, press any one?" Since the operating system is turned on each time, you must guide two implied files IO.SYS, MSDOS.SYS, and Command.com files to complete the launch of the machine. This problem occurs is due to the lack of these two implies files. The solution is to change a good system disk boot machine; use the sys.com command (format: sys c:) to copy IO.SYS and MSDOS.sys on two implied files to the hard disk, the fault disappears. 19. After the power-on password is lost, the rescue method is lost. If you have forgotten the boot password set by the BIOS, what should I do? Don't tighten, things have a solution. Starting from the 586 computer, there is a BIOS password shield jumper on the motherboard. Just find the jumper, then according to the manual's operation method, you can easily give the password. But what if your computer is 486? Don't be discouraged, check if the motherboard's BIOS is Award. If so, you may wish to try a few universal passwords below: (1) Syxz; (2) EBBB; (3) h996; (4) Wantgirl (5) award. Please pay attention to case. 20. How to get the old BIOS program?
On the 586 computer, the general motherboard provides the function of upgrading the BIOS. Please refer to the operating manual of the relevant motherboard. The following is simply introduced. First, open the chassis, set the BIOS Obsole Jumper to Enabled (the location of the route, please check the manual), default is disabled. Start your computer with a boot disk that does not contain config.sys and autoexec.bat. Insert the disk with the main board into the computer floppy drive, start the PFLASH. When the program is started, select 3. Select 2 again. At this time, the program will prompt you to give the BIOS file name, you just type the file name of the file you want to upgrade (note to give the full path), then press Y, press Y, press Y, press N, press N, press ESC, shut down. Don't forget to jump back the jumper, turn it back, everything is very big. twenty one. An analysis and exclusion of 11 kinds of faults that cannot be guided normally. In use, there is often a variety of faults. Sometimes it is not possible to enter the operating system normally, that is, the machine cannot be guided normally; with the fault, the corresponding information will appear on the screen, sometimes there is no prompt. How do I not guide the failure from the boot process of the PC? Below we analyze the various phenomena that do not boot from the boot process. (1) After booting, the system has shown that after the memory is over, "Wait", after a long time, "HDD FAILED" or "FDD FAILED" appears, the hard disk setting is wrong or the floppy drive settings is wrong, press F1 is executed down, or press the DEL key to enter the BIOS setting. At this time, the system stops moving. Press the DEL key to enter the BIOS setting, check if the hard drive is correct, if it is not correct, correct it. If the hard disk is not detected, the hard disk is faulty. After setting, save the setting parameters and exit it, you can enter the system. (2) After booting, the memory is complete, the system report keyboard is wrong, and it is not running down. At this point, shut down first, see if the keyboard is plugged in, if you don't plug it, turn it again, see if you can troubleshoot. If the fault is still, the keyboard or motherboard has a problem, and needs to replace one of them to troubleshoot the report keyboard. (3) After the boot is turned on, after the memory is detected, the newspaper BIOS battery has failed. At this time, the system stops. If it is a newly replaced motherboard, enter the BIOS settings. If no motherboard is replaced, it will show that the BIOS battery failure or charging line of the motherboard is problematic, and the motherboard needs to be replaced to troubleshoot. (4) After booting, memory, hard disk, and floppy drives are detected, and there is no prompt to stop. This may be because the hard disk does not have a system file or the system's IO.SYS, the msdos.sys file is destroyed. At this point, you can start with the system floppy disk, and execute the SYS C: command to the hard disk. (5) After booting, report "No Systemdisk or Disk Error). Possible causes are: the floppy disk in the A drive is non-system disk and driven from A; there is no system file on the C disk; ie there is no command.com, io.sys, msdos.sys. The system file on the C drive is destroyed; physical damage is physically damaged by the surface of the hard disk medium. The solution is: Insert the system disk in the floppy drive; execute the SYS C: command, and upload the system to the C drive; repair or update the hard disk. (6) After boot, the "Disk Boot Failure" is reported.
This shows that the system file reads out of the C drive may be because the implied file is destroyed, or the DOS boot record on the hard disk has an error. The solution is as follows: First, start using a disk, run "Sys C:", start from the C drive. Second, if it is unable to start, then "Format C: / S" is run, and then the system will be started. Third, if it is unable to start, check the virus to see if there is a guided virus. Fourth, if the above methods are invalid, it means that the hard disk is physically damaged, and it needs to be repaired or updated. (7) After boot, report "incorrect DOS version". IncorRect dos version. This shows that the version of the two implied files in the system under the Command.com file of the DOS system on the hard disk is incorrect. This fault may be because when all files on the A disk are copied into the C drive, the original command.com is caused by the original Command.com. Turn it to copy in the correct command.com file. (8) After boot, report "Missing OperatingSystem). This shows that the DOS boot record on the C drive is incorrect, which may be that the DOS partition is not formatted, or the DOS boot record is physically damaged. The solution is to format the hard drive first. If it is not possible to start or cannot format the hard disk. (9) After booting, the "invalid partition table" is reported. This shows that the partition flag is incorrect, or the sector where the partition is located is incorrect. The solution is to correctly restrict the hard disk and set the active partition. (10) It is sometimes not booted. This is because the virus destroys the system file, change the boot record, and destroy the file allocation table. Therefore, if there is no guidance failure that cannot be judged, you can check if there is a virus and do other processing. If there is a guided virus and can't kill, you can reset the guiding area with manual methods (such as: debug). (11) The above analysis is the fault situation under the DOS system. If the Windows operating system, when the system starts, when "Starting Windows 95 ...", stopping, which is not guided.
The solution is as follows: First, turn it on, start Windows to enter the security mode, start Windows in safe mode, if you can start, explain conflicts between the hardware devices of the system, you need to debug a variety of equipment to avoid interrupt conflicts; The security model can't start, you need to check it to see if there is a virus. If there is a virus, after clearing, see if Windows is started; three, if it is still unable to start, reloading Windows; 4 is when Windows cannot start, sometimes it can be repeatedly started multiple times until it starts correctly. The condition of this method is that after each restart, the performance of the system is different, that is, the second time the startup content seen in the first time is more.
Eighty-one, the Word menu will not see first let's take a look at the cause of the menu and toolbar. Select the "Custom" command of the Tools menu in the normal Word window to pop up the dialog box. Within the "Toolbar" tab of the dialog, all items in the tick are displayed in the Word window, and if all deselects will appear, there will be a phenomenon that the menu and toolbar will appear. I know the principle, we have a way to let them return to the original. Method 1. Re-pop up the "Custom" dialog box: You can use the Alt T C shortcut to activate the "Custom" dialog, reallocate the "Menu Bar", "Common", "Format" options, Word Window An appearance menu and toolbar immediately. Method 2, restore the default status of Word: Word's related settings Save in a template file called "Normal. Dot", we can use the Start / Find / File or Folder command (or in the Word installation directory) Templates Directory Find Normal. DOT, remove the file, then restart Word, the system generates a new "Normal. Dot" file, return to the original default state, the menu and the common toolbar will appear. The strange restart fault General Computer has a restart failure because the power supply is insufficient, and the power supply is abnormal, or the computer has a circuit failure outside the computer. But the author encountered this is a motherboard reason to restart the fault.
Configuration: P4 MFM motherboard, 256MB modern DDR, 40GB Xije cool fish, small film tyrant 7900TI 64MB DDR, Great Wall 300W P4 power supply.
Fault Phenomenon: The new computer, the computer is sometimes restarted, saying that it is not allowed, and sometimes it will be restarted, sometimes it is not restarted for one day.
Fault Solution: The author went to the customer to check, the computer did not restart once in a afternoon. It is estimated that there is no problem with computer hardware, but it is still reloaded the system and upgrades anti-virus software. But how long, the customer calls, or the old look, the author judges that this situation is likely to have problems with the power line in the customer's home. The author has encountered such a problem: if the computer and refrigerator, air conditioner, etc., the home appliance, which starts, using a line, when the above electrical appliance is started, a current close to its normal operation, then the voltage of the line It will decrease significantly. When it is less than 170V, the computer will restart.
In addition, if the client's household line has a poor contact, when the household appliance is working for a long time, the virtual connection is averaged because the contact resistance is large, it will heat, when heat accumulates to a certain extent, the wires come into contact with the wires It will be thermally expanded instantly, and the restart is also generated. In view of the above reasons, the author comes with a UPS power when it goes to the customer, carefully check the line, and the computer should not exist in the estimated Item alone. Because the failure is not regular, finally leave the UPS to the customer.
On the second day, I went to work, and the customer did a reboot. No way, the author shipped the computer to the company's disassembly check, put the motherboard, graphics card, power supply, and hard disk on the test bench one by one. In the test, the author did not intend to move the power cord, and the host immediately rebooted. The author finds that as long as the power cord is used, the computer will immediately restart. Finally, check it carefully, found that a footer-on foot of the P20ATX power outlet is falsely with the motherboard tin plate, and there is a very slight crack. It turned out that it was in the monster! Due to the warranty period, the author changed the same model of the motherboard for the customer to give the customer. Restart the fault has never appeared. Saving the 98-day friend of the unable to start can't start, and the emergency pen will be diagnosed. Open the machine, display the following information:
Starting Windows 98 ... Unknown Flash Type. Em Disk I / O Error Replace The Disk, And The Press Any Key.
This is my second time I encountered the same fault. I remember that I first partitioned, format, and reinstalled the Windows 98 system and some common software, which took several hours, especially the old acoustic card driver installed, but also a lot of effort. Is it necessary to repeat the last complicated steps this time? I think of this is a little cold, so I decided to find a simpler solution.
I tried to boot from the floppy disk, successfully tried to enter the C drive, using the DIR command to list the file directory, suspected that the boot file on the C-zone was destroyed, and the "SYS A: C:" command delivery system, After restarting the machine, the fault is still.
I think the hard drive cannot be guided. It is generally a big relationship with the hard drive's main guidance sector, and I still remember to use the "fdisk / MBR" command to fix most hard drive's main guidance sectors, why not try it! ! So immediately start from the floppy disk, first execute the "fdisk / MBR" command, then use "Sys A: C:" to transfer the system file, then restart the computer after completion, and the C drive is successful. Unfortunately, you can only enter the DOS state at this time, and Windows 98 cannot be started. Check it carefully to check the system boot file, found that the number of bytes of MSDOS.sys is much smaller. After modifying the properties of this file, view its content with EDIT, and there is a lot of command lines. I immediately started from another machine COPY a MSDOS.sys file, restarting the computer again, and finally appears the Windows 98 interface, and the system is also recovering.
From this experience, I summarize it. When the hard disk can't start, don't worry, you must carefully analyze and find the reason in step by step, try to find the best solution. Although re-partitioning the hard disk, formatting the re-reinstall system can completely solve the problem, but the cost of labor is still destroyed, and the original system and data are also disappeared.
