1. Guarantee the correct BIOS settings. The settings in the BIOS must be appropriate, and the wrong BIOS setting will cause you to crash when running Windows.
2. Circular accessories are often checked. Running in the absence of board contacts can cause a system crash, so when replacing the computer accessory, be sure to make the board with the motherboard.
3. Regular cleaning chassis. Too much dust will cause the board between the board, causing the system to crash in the operation, so the chassis should be cleaned at any time, do not let too much dust in the chassis.
4. Stick to the virus seriously. For CD or floppy discs, don't use it easily, attachments to the email, you must first check it with an anti-virus software.
5. Should be turned off in the correct operation order. Don't turn off the power before the application is not properly ended, don't turn off the power, or cause the system file damage or loss, causing a crash in the start or run.
6. Avoid multitasking simultaneously. Do not run other software during the execution of disk finishing or use anti-virus software, do not run other software, otherwise it will cause crash.
7. Don't get new. The drivers of various hardware do not have to be updated at any time, because the drivers developed often have bugs, will cause damage to the system, causing system crash, the latest unique is best.
8. When uninstalling the software, use the contrary / uninstallation mode in Windows or Windows, do not directly delete the program folder, because some files may be shared by other programs, once these shared files are deleted, can cause application software that cannot be used Cancer.
9. When setting up hardware devices, it is best to check that there is no retention interrupt (IRQ), do not let other devices use this interrupt number to avoid interrupt conflicts, resulting in system crash.
10. When surfing online, don't open too many browser windows, otherwise it will lead to insufficient system resources, causing system crash.
11. If your machine memory is not very large, don't run programs that take up memory, such as Photoshop, otherwise it will be easy to crash.
12. For system files or important files, it is best to use implied properties so that these files are deleted due to error operations, causing system cranes.
13. When modifying the hard disk main boot record, it is best to save the original record and prevent the original boot record from being restored due to failure of the modification.
14. CPU, graphics card and other accessories generally do not overclock, if it is really necessary, pay attention to the temperature, CPU, graphics card, etc. of the overclocking board, automatically restart or crawl in the non-normal frequency and temperature, and burned the CPU, graphics card, Motherboard.
How to effectively reduce the crash of the computer
The crash of the computer is a problem that makes all computer enthusiasts.
For frequent blue screens in the computer, frequent crashs, once again, restart is really uncomfortable. Moreover, the loss of hardware caused by the frequent restart of the computer is several times more than the normal operation, which has greatly increased the chance of hardware damage.
However, the use of Windows 9x operating systems, but the crash is an unavoidable thing, the reason is due to the unstable core unstable in Windows 9x operating system.
Although the crash is inevitable, the author is in a long-term and crazy struggle, or summed up some ways to effectively reduce the computer crash, it is not exclusive, and it is impossible to give it to the readers. I hope that everyone can reduce the computer. Some dead turns, more stable.
There are a lot of reasons for the crash, but in general, there are two categories: hardware reasons and software reasons. Below I will tell you about it.
Hardware
1. The current CPU and display card have a new process, so there is a good overclocking performance, but the overclocking is extremely easy to cause unstable or even crashing machines (damage hardware, no matter). For crash phenomena caused by overclocking, it should be reduced in time, or the rated operating frequency is restored to ensure the stability of the computer. 2. When the computer is replaced, it must be checked again later, see if the hardware has been plugged in, to prevent the deadline from causing the dead.
3. Sometimes due to the conflict between the various hardware, try to refresh the new version of the BIOS, update the driver or change the interrupt number of the device in the system, please replace the hardware.
4. The BIOS of the motherboard must be set, although many newspapers, magazines and websites now teach you how to set the BIOS to optimal, but I don't know the optimal setting but not necessarily the most stable. If the BIOS setting causing a crazy, the BIOS should be immediately restored to the factory default settings.
5. The computer host must equip high quality and high-performance power, because the current power consumption power consumption is large, especially when overclocking, the power consumption will be doubled. If the power supply is insufficient, the hardware will be powered. Insufficient situation, causing a crash.
6. In the case of small memory (less than 128m), it is best not to run more software and the game or run multiple programs at the same time, which will result in insufficient physical memory, causing a crash.
7. Before upgrading the motherboard or the BIOS of the card, you must first determine if the BIOS of the upgrade is consistent with the model of the board, and strongly recommends backing up the original version to prevent in case.
8. There is a lot of dust in the air. In the case of a long time, there will be a lot of dust, and it should be cleaned in time, otherwise it will seriously affect the heat dissipation effect, and the dust contacts will cause short circuit when the dust contact board circuit is caused, causing a crash.
9. Temperature, especially when the summer is coming, especially when the summer is coming, the weather is hot, and if the temperature of the fitting temperature will cause a crash.
Software articles
1. For software, discs, or pirated software that you calendar, must not be used easily to avoid computer viruses, causing crash.
2. Be sure to properly shut down the computer, absolutely not directly turn off the power, otherwise it is easy to cause the system file loss or damage, causing a crash.
3. When deleting the software, do not delete the directory where the software is located, so that a large amount of garbage is left in the hard disk and the registry, the more long time will be, the more agreed, leading to the system burden, and finally the system will be overwhelmed and dead. The correct way is to remove the software with the uninstaller using the software.
4. If the computer is always running or the system resources are low, if you want to run large software, you must first restart your computer, otherwise it will cause a crash due to insufficient system resources.
5. It is best to use software or hardware-driven test versions, because there is a large number of bugs and instability in the test version, which is easy to cause crash.
6. It is best to use hidden properties for system files, so that the crash will be caused by accidentally deleting the system file.
7. When Internet access, do not open too many web pages, so as to avoid the system burden, causing a crash. Moreover, don't open some unclear web pages, because there may be some malicious code, modify the system, resulting in a crash.
Revision of computer cranes in a comprehensive
Cancer is a matter of trouble that operators is quite troubles. The performance of the crash is more "blue screen", unable to start the system, the screen "fixed" does not respond, the mouse, the keyboard cannot be entered, the software is not normal interrupt. Although the cause of the crash is multifaceted, it does not leave its part, and the reason will never be separated from hardware and software. Craft machine caused by hardware reasons
[Winter heat] Display, power supply and CPU are very hot in work, so maintaining a good ventilation situation is very important. If the monitor overheating will cause color, image distortion even shorten the monitor life. Too long working hours will also cause the power supply or display to heat the heat and cause the computer to crash. The cooling of the CPU is an important issue that is related to the stability of the computer operation, and is also a "hardest hit area" in the heat dissipation failure. [Improper movement] A large vibration in the computer movement often causes the internal devices in the machine to loosen, resulting in poor contact, causing a computer to crash, so it should avoid dramatic vibration when mobile computers.
[Dust killer] excessive dust in the machine will also cause crash failures. If the floppy head or the optical drive laser head is contaminated with too much dust, it will cause a read and write error, which will seriously cause the computer to crash.
[Equipment mismatch] If the motherboard clock, the CPU cluster does not match, the old motherboard is overclocked, and the outer frequency is fixed too high, and it may not guarantee the stability of the operation, and thus frequent crash.
[Software and hardware is not compatible] 3D software and some special software, may not start properly on some microcomputers or even installation, which may have problems with hardware and software compatibility.
[Memory bar fault] mainly the memory bar is loose, the duly welding or memory chip itself is caused. The memory strip contact failure should be excluded according to the specific situation. If there is a problem with the mass of the memory, the memory needs to be replaced to solve the problem.
[Hard disk failure] Mainly hard drive aging or causes bad tracks, bad sectors due to improper use. This makes it easy to crash when the machine is running. Dissipitable processing can be performed with special tool software. If damage is severe, it can only replace the hard drive. In addition, for the motherboards that do not support UDMA66 / 100, it should be noted that the setting of the hard disk operation mode in CMOS.
[CPU overclocking] Overclocking increases the working frequency of the CPU, and it is also possible to make its performance unstable. For the reason, the speed of the CPU accesses data in memory is faster than the speed of memory and hard disk exchange data, and the overclocking makes this contradiction more prominent, exacerbated the case where the required data is not found in memory or virtual memory, This will appear "exception errors". The solution is of course simpler, that is, let the CPU back to normal frequencies. [Hardware Resource Conflict] is due to the conflict of sound card or display card, causing an exception error. In addition, the interrupts, DMA or ports of other devices have conflict, which may cause a few drivers to produce an abnormality to let the crash. The solution is to start with "Safety Mode" and make appropriate adjustments in "Control Panel" → "System" → "Device Management". The registry can be modified for the case where an abnormal error is generated in the driver. Select "Run", type "regedit", enter the registry editor, find and delete all the "primary keys" and "key values" associated with the driver prefix string by the "Find" feature under menu, restart.
[Insufficient memory capacity] The larger memory capacity, the better, should not be less than 0.5 ~ 1% of the hard disk capacity, if this is the problem, you should replace the capacity of the memory strip as possible.
[Inferior Parts] Small number of unscrupulous businessmen use the quality of the quality board, memory, some even selling counterparaga and Remark, such that such machines are unstable when running in operation Cancer is inevitable. Therefore, users should be vigilant when purchasing machines and can be used to test computers with some newer tool software, long-term continuous test (such as 72 hours), and strive to be as long as possible.
Craft machine caused by software reasons
[Virus infection] Virus can make computer work efficiency drop sharply, causing frequent crash. At this time, we need to use anti-virus software such as KV300, Jinshan Taxi, Rising, etc. to completely check, anti-virus, and make timed upgrade anti-virus software. [CMOS settings] This fault is very common, such as hard disk parameter settings, mode settings, and memory parameters are not properly causing that the computer cannot start. If the memory without ECC functions is set to have an ECC function, it will cause crash due to memory errors.
[Mistaken deletion of system files] Since Windows 9x is started, there is a file such as Command.com, IO.SYS, MSDOS.sys, if these files are destroyed or misused, even in CMOS, various hardware settings are correct, no mistakes. Workaround: Start your computer using the startup disk of the same version operating system, then type "Sysc:", re-transfer the system file.
[Initialization files were destroyed] Since Windows9x starts to read System.ini, Win.ini and registry files, if there is config.sys, autoexec.bat files, both files are also read. As long as there is an error message in these files, it is especially important to have a dead machine, especially System.ini, Win.ini, User.dat, System.dat.
[Dynamic Link Library (DLL) Loss] There is also a type of file in the Windows operating system. This is the dynamic link library file extension DLL, which is a shared class file from nature. That is to say A DLL file may have multiple software to call it at runtime. If we are deleting an application, the software's anti-installer records the files that have been installed and ready to delete them one by one. At this time, it is easy to have a dynamic link library file that is deleted. The situation used by the software, if the lost link library file is a more important core link file, then the system will crash, even crash. We can use tool software such as "Super Rabbit" to delete the useless DLL file, which will avoid accidentally deletion.
[There is too small for the remaining space of the hard disk] If the remaining space of the hard disk is too small, since some applications require a lot of memory, it is necessary to virtual memory, and virtual memory is provided by the hard disk, so the hard disk is sufficient. The remaining space to meet the needs of virtual memory. At the same time, the user also develops a regular finishing hard drive to clear the good habits of junk files in the hard disk.
[BIOS upgrade failed] should back up the BIOS to prevent it, but if your system needs to upgrade the BIOS, it is best to determine if the BIOS version is in line with your PC before upgrading. If the BIOS upgrade is incorrect or an unexpected power outage occurs during the upgrade, then your system may not be able to start. So don't know the model of BIOS before upgrading the BIOS. If you use the BIOS upgrade tool to back up the current BIOS, then copy the previous BIOS in the disk. At the same time, see if the system supports BIOS recovery and knows how to recover.
[Improper software upgrade] Most people may think that software upgrades do not have problems, in fact, some components shared in the upgrade process are also upgraded, but other programs may not support upgraded components to lead to each Problem.
[Abuse of beta software] It is best to use software test version, because test software usually has some bugs or is not stable enough in a certain aspect, and a program error, crash or system cannot start.
[Illegal uninstall software] Do not delete the directory where the software installation is installed, if you delete it directly, there will be many garbage in the registry, and the Windows directory. Over time, the system will also become unstable and causing crash.
[Use piracy software] Because these software may hide viruses, once executed, you will automatically modify your system, so that the system has a crash in the run.
[Defects for application software] This situation is common, such as running those 16-bit applications running in DOS or Windows 3.1 in Win98. Win98 is 32-bit, although it is compatible, there are many places that cannot be coordinated with 16-bit applications. There are also situations, such as peripheral drivers that are used under Win95, when the operating system is upgraded, there may be problems, so that the system crashes or cannot be started normally. This situation should be found to find the new version of the peripheral. [Too many programs started] This allows system resources to consume, so that data needed by individual programs can not be found in memory or virtual memory, there will be an exception error.
Illegal operations illegally open or release the relevant procedures with illegal format or parameters, it will also cause the computer to crash. Please note that you should keep in mind the correct format and related parameters, don't open and release unfamiliar programs.
[Not normal shutdown computer] Do not use the power button in the chassis directly, otherwise the system file is damaged or lost, causing automatic start or running. For Windows98 / 2000 / NT, this is very important, if serious, will cause the system to crash.
[Memory conflict] Sometimes running a variety of softwares, but suddenly, it is inexplicably crafted, and then running these applications after restarting, this is a fake crane. The reason for the emergence is mostly the conflict of Win98 memory resources. Everyone knows that the application is running in memory, and the memory space can be released after closing the application. However, some applications are designed because of the reasons of design, even if the memory is not completely released, the next software requires the use of this block, there is a conflict.
General solution for boot black screen
First, check the power supply, computer power, power interface
1. Check if the interface and power cord of the chassis power supply are intact. If the excuse and power cord are damaged, the break should be replaced in time.
2, check the motherboard power cord socket. If there is no damage, pull the socket and then insert it. When the power switch is pressed, gently move the power cord to see if there is a reaction to determine whether it is because the power cord is poorly contact or the solder point is caused. The power is not connected.
3, use an alternative method to try this power supply to other machines, and you can also use a good power supply to see if it can be started to determine the power supply. Special pay special attention to check whether the switch on the power supply is turned on, some power supplies are switched.
Second, use the minimum system method
1. Take the motherboard, first with a brush (quality is good, must not be removed, the author once encountered the hair of the film that the graphics did not work off due to the hair removal of the graphics card, but the most It's easy to blow with a blown cold fan, use the skin tiger, so after cleaning, a lot of faults caused by dust naturally!
2, plug in the CPU, the memory, the graphics card, see if the machine is lit. At the same time, an alternative method can be used, and the good CPU, memory strip, and graphics card are used to determine the fault. At this time, for some jumpers (hard jumpers) about the CPU, pay special attention to whether or not they are set correctly. Especially in the case of upgrading the CPU, you must first look at whether the motherboard supports the new CPU. To avoid setting the voltage over high CPU.
3, if the machine is still not bright under the minimum system, it is determined that the CPU (the jumper settings is correct), the graphics card, and the memory strips should be doubted to question the motherboard.
14 cases of judgment code for computer cranes
Everyone who uses a computer or more people encountered a problem of crash, the following is a common crash situation for your reference:
◆ Case 1: Board, card contact, loose, or slot on the board is broken, or simply display cards, memory, etc., the memory is bad, causing the display to not light.
◆ Case 2: The voltage is too large, causing the board, card current or large or small, sometimes damage the hardware. So selecting a power supply that can play a super voltage is critical, or the stabilizer. ◆ Situation 3: Printers, burner, scanners, etc., but plug-and-play technology enable the system to detect these devices at startup.
◆ Situation 4: Overclocking exceeds the fire, sometimes the display is not bright, sometimes it is to enter the system, and the severe cases will cause the CPU to be burnt.
◆ Case 5: If the host runs properly, there is also a sound running of the hard disk, but the display is not bright, may be the display of the display, or the display signal line is in contact with the display, or it is possible that the display power supply is not plugged.
◆ Situation 6: Only listening to "嘀, 嘀" mono long sound, it is estimated that it is a problem with memory, try to try a slot, and it is still not possible to surrender.
◆ Situation 7: Indows95,98 The system needs to use a part of the hard disk as a virtual memory, and the remaining space of the hard disk is too small, which will also cause the crash.
◆ Situation 8: The virus causes the crash.
◆ Situation 9: The software of the software causes the crash.
◆ Situation 10: Running software conflicts, such as 16-bit and 32-bit software can cause crashs.
◆ Situation 11: When online, hacker invades.
◆ Situation 12: System System Sino-Chain file. DLL is lost, causing Windows system to paralysis.
◆ Situation 13: Error modifies the system registry information, causing the Windows system that cannot be started.
◆ Case 14: The machine runs too slow, resulting in crash
Preventing the 25th stroke of the computer
1. Install too much operating system on the same hard disk causes the system crash.
2, CPU, display card and other parts should not overclock over, pay attention to the temperature, otherwise, it will be inexplicably restarted or crazy when starting or running.
3. When replacing the computer accessory, be sure to plug because the accessory contact can cause the system to crash.
4, BIOS settings should be appropriate, although it is recommended to set BIOS to optimal, but the best is not the best, sometimes optimal settings will cause start or run deadlines.
5, preferably equipped with a voltage regulator, so as not to cause the voltage to cause crash.
6. If there is conditional, add a UPS to make the computer will not cause crash after power outage.
7, for the unknown floppy disk and disc, do not easily use, the software attached to E-mail, use KV300, Rising and other anti-virus software to use, so as not to transmit the virus, it is the system crash.
8. When the application is not normal, don't turn off the power, otherwise the system file is corrupted or lost, causing automatic start or running. This is very important for Windows98 / 2000 / NT.
9. In the installation application, if the prompt dialog box "is overwritten", it is best to choose not to overwrite. Because usually the current system file is the best, it is not possible to determine overworked files according to time (unless you are concerned about the file).
10. When uninstalling the software, do not delete the shared file, because some shared files may be used by the system or other programs, once deleted these files, the application software will not start and crash, or the system running crash.
11. When setting up hardware devices, it is best to check that there is no retention interrupt number (IRQ), do not let other devices use this interrupt number, otherwise it causes IRQ conflicts, causing system crash.
12. When loading some software, pay attention to the order, because some software programming is irregular, it is not possible to run in the first, but in the final operation, this will not cause confusion of system management.
13. When running a large application (such as Office 2000), do not exit the previously running programs in the running state, otherwise it will cause crash of the entire Windows 98 system. 14. In the case where the memory is small (such as 4MB-16MB), it is best not to run a large-memory application, otherwise it is easy to have a crash at runtime. It is recommended to save the currently used files when running these programs.
15. For system files or important files, it is best to use implied properties so that these files are removed or overwritten due to misoperation.
16. When modifying the hard disk main boot record, it is best to save the original record to prevent the original hard disk main boot record due to failure to fail.
17. It is best to use the software test version because the beta is not stable in a certain aspect, and the system will not start after use.
18. Do not run 16-bit applications in Windows95 / 98, because 16-bit applications conflict with 32-bit applications in Windows, causing crash or unable to start.
19. Before upgrading the BIOS, you should determine the upgraded BIOS version, and you should save the original version first to avoid upgrading errors to make the system unable to start.
20. Try not to use pirated software, because these software hide a large number of viruses, once executed, automatically modify your system, so that the system has a crash in the run.
21. In the chassis, there may be a large amount of dust. If dust is contacted by the circuit, the system will make the system unstable or crash.
22. When performing a disk fragmentation, do not run a large application software, otherwise it will cause a crash.
23. Do not run other applications during the hard disk with anti-virus software to prevent system crash.
24. When Internet access, don't open too many browsing windows at a time, leading to insufficient resources, causing crash.
25. When shutting down your computer, don't use the power button in the chassis directly, because the power button directly causes the loss of the file, so that the next time you can't start normally, resulting in a system crash. Analysis of Causes of Computer Crash and Cancer
When your computer is dead for no reason, what happened? Why is there any operating system to stabilize than other operating systems? You will know some after reading this article.
All computers will crash, and any operating system is unsaptable. (When you write this article, you will have a collapse =)). However, it is not a simple reason why it is not a simple matter: Professor Daniel Jackson, a Professor of the Massachusetts Institute of Technology. Professor Jackson believes that its potential root cause is that hardware and software open companies have tried to quickly launch their products in "Internet Time", which is the effect of product quality and reliability.
Usually one operating system is composed of millions of rows of code and hundreds of programs. At the same time, hundreds of people work together, this is not an easy task. And the end result is difficult to achieve perfect. In order to find out those small faults, the developers hire testers when the software is close to completion. When the problem finds, the patch is written to correct these errors. They do prevent crash. However, the original error code is not deleted. At the same time, Professor Jackson also pointed out that testing could not find out the design level of defects.
There are three main sources that cause collapse: 1, the app. 2, device driver. 3, the operating system. Most collapse stems from the top. Errors often occur when an application tries to access another application's memory. For example, when Word starts using the memory space reserved for Excel, it is like an international chess player moving another player's chess. At this time another player or referee will announce: "The game is over".
In theory, a text processing software does not cause crash of the entire computer, but in fact, the situation is often the case. That is because the operating system seems to be the referee just said, when he found that a program is modifying another program, it will blow whistle because it may lead to the instability of the system. Different operating systems have different reactions to the same problem. If the early Windows version will happen, "Blue Screen Crafts" will occur, and more and more more stable operating systems build the "virtual wall" on each application. So even if a program cannot be executed as planned, other programs are not interrupted, causing the crash of the entire system. Device Drive is a program that communicates operating systems and hardware. BUG is usually found after the product is released. Usually the manufacturer provides driver updates after product release. New applications (especially image editing software) generally require new drivers to eliminate problems caused by the original drive. Microsoft claims that XP will increase the reliability than the old Windows version of the old Windows version by the automatic update driver in Windows XP. Old computer drivers can be found on the hardware manufacturer's website.
Your operating system rarely leads to crash, but there are many situations that cause crash, such as the wrong application memory address. If you can't verify memory capacity, you will make the system become unstable. The BUG of the operating system will also appear because of the increase in hardware and software. Uncompatible crash
The computer has recently displayed insufficient memory. After about an hour of running, a blue screen failure will suddenly appear. How long does it take time after starting a reboot, and the failure is still.
In the use of multiple anti-virus software, the fault is still existing after the system is reinable, so the author begins suspected that it is not caused by a virus or a Windows installation error. View the task list before the boot is about to appear, and the memory has been loaded with hundreds called "winold", and the software and Microsoft's instruction documents are available. This is a DOS application is compatible with DOS application. Sexual issues.
It turns out that I use a system integration software developed by Win95 era. The software is constantly reading the external information transmitted in the form of a compressed package during operation. Each time a compressed package is read, the included pkunzip program is automatically invited, and pkunzip is the DOS environment. Application, does not automatically exit after completing the task, so this program is constantly residing in memory, which will cause a serious exhaustion of memory resources for a certain period of time, and ultimately blue screen phenomenon. After understanding the cause, you can solve the problem: find the pkunzip.exe program, click "Programs" in the property, select the check box before "Prohibiting the MS-DOS Program Detection Windows", confirm, and try the failure disappear.
In addition to this prohibition detection method, if you use WinXP, you can use compatibility mode to run the program, WinXP automatically loads the virtual machine for these old programs. It seems that it is suspected to be a virus damage, but the anti-virus software cannot process the fault, to see if Windows has caused problems with previous program compatibility. Although the worm virus often opens countless process occupies system resources, the Windows shows that the resource is depleted, and it is not necessarily caused by the virus. Preventing tips for crash
Computer virus infection, hacker attack, "millennium" episodes, use improper operation, or frequent installation and deletion of various applications, will cause the system to start normally. To prevent the prevention, the following should be copied to the second hard disk or floppy disk in the second hard disk or floppy disk.
C: Autoeexec.bat, Autoexec.dos, config.sys, config.dos, msdos.sys
C: Windows directory under Control.ini, System.ini, Win.ini, System.dat, User.dat
Once the machine does not start normally, try to copy the above file back to the original directory, which can often be returned to return. Whether it is a compatible machine or a machine, the magical crane phenomenon will appear in the process of use. Cancer is a more common failure, and it is also a difficult condition that is not easy to solve. Especially when the computer crashes, we can't use software or tools to detect the machine, and repair it in a headache. 1. Cancer is generally manifested:
1) There is no reaction after power-on, there is no reaction, the power indicator is not bright, the fan is not turned;
2) The system cannot start normally, and suddenly the screen is stagnated during the startup process;
3) Display black screen in the startup process or in the use process of display black screen;
4) The image "solidification" is not updated, but the keyboard light can be opened and closed;
5) The keyboard is locked without reaction;
6) The mouse can be moved normally but the host has no response;
7) The software is not working abnormal interruption;
8) Regular blue screens appear.
9) Regularly report memory errors or overflow.
How can we quickly solve the failure, let the machine restore normal work?
II. Troubleshooting
Specifically, the crash phenomenon can be divided into two cases of hardware and software. :
Hardware
The crash caused by hardware is often: the market is unstable, the main power supply output voltage is too low or too high, the temperature in the chassis is too high, the memory temperature is overheating, the CPU temperature is too high, overclocking, interference, peripherals are faulty, board The card contact is poor, and the data line connected to the peripheral connection is poor.
(1) The city electricity voltage is unstable
The computer voltage range is generally between 180V-240V. When the voltage is lower than 180V, the switching power supply output voltage is too low or protected. At this time, the host is easy to restart or automatically shut down; when the voltage is higher than 240V, the main electric input voltage exceeds The allowable operating range of the host power supply, but due to the discrete of the components of the circuit, the power supply may not be protected, and the secondary power supply output may be high, and the crash will also cause crash.
(2) The host power is not completely damaged
When the main unit is damaged, the voltage output may have deviation or the current output is insufficient, resulting in lack of effective load rate, which will also generate a crash. At present, the switching power supplies used by the computer host use TL494 or similar PWM control chips, and the comparator generally uses the LM339 or LM393 to control whether the host is transmitted. When the chip is faulty, we will have a wire short circuit and a black line (some books asking for 100o resistance, in fact, there is no need to pass the electrical resistance of 2K in the internal circuit, even if it is shorted, There are only a few milliamps), the fan of the power supply works, and the output voltage of the multimeter is basically normal. But after the access circuit, the power supply cannot work properly. This is mainly after the chip is damaged, the voltage sampling is incorrect, can not be able to bring heavy loads, as long as the model chip can be replaced.
I have encountered it once, a hit switch power supply, after using the host If you don't die, it's okay, it's okay, didn't burn the motherboard. (3) Poor heat dissipation in the chassis
Excessive dust in the chassis can also cause the system to crash. Dust is the enemy of the computer, too much dust adheres to the CPU, chip, and the surface of the fan can cause heat dissipation of these components or poor contact; the dust on the printed circuit board often leads to a short circuit in a humid environment. Both conditions can cause crash. This situation is common in some old computers, there is no response when it is placed or two years, and there is no or after booting, and there is a crash in the machine to have a crash. Because the temperature sensor of the PIV computer is integrated inside the CPU, its temperature is accurate, so the boot CPU temperature is generally about 50, which is much higher than the detection temperature of the Socket 370 CPU (about 30). However, because the PIVCPU has a large amount of heat, it is necessary to select the corresponding CPU fan based on the CPU style when selecting the CPU fan, don't let the small mala truck, or the crash is constantly. Workaround: We can use a brush to scales dust, and then clean the gray tip of the board with a hair dryer (cold fan).
Note: Do not put hair brush and cotton swabs, cotton leaves on board and components into new cranes. If we can clean the dust and the dust inside the monitor in one year, our love machine will not have a strike without reason.
(4) overclocking
Many DIY friends like to improve their performance through overclocking, so you can save money more. But there is a big hidden danger: minus crash, the heavy scrap can cause CPU, memory and hard disk.
I have had a overclocking experience, the 66 foreign motherboard is hard to over-83 foreplay, just starting to use well, when I am, when I am, when I am so self-friendly, two days later, suddenly during operation, The system prompts that the hard drive cannot be found. I still don't care, then get more and more frequent, and finally I can't find a hard drive in CMOS. Specially now p4cpu has a higher integration, some have used 0.09 micron lines. When we overclock, it is easy to cause internal electron excess attenuation, and finally the connection line is completely broken, causing CPU scrap.
(5) Motherboard jumper error
Some motherboards are used to use route or coding switches, CPU or memory voltage selection use of jumper settings. At this time, we must set the main frequency multiplier parameters of the corresponding CPU and the corresponding use voltage according to the instructions. If the settings may cause overclocking to the CPU, when setting the parameters, it is possible to crash or enter the system. Sometimes we do not jump back to the original position after discharging CMOS, then the black screen does not start when power-on start. Some motherboards support both SD and DDR memory, pay attention to the two voltage settings of 2.5V and 3.3V on the motherboard. In particular, the core voltage setting of the CPU cannot appear, otherwise it is easy to cause the CPU scrap.
(6) Damage within peripheral internal circuitry
When the external circuits such as a display, the printer, and M is damaged, after connection with the host, the corresponding port is shorted, and when the host applies the self-test, it cannot pass or cause power protection. Some engraved machines, the programmer is applied after the host is applied, and the host cannot be started after the host is powered. (7) Poor contact with the data line connected to the peripheral.
When the peripherals are loose with the host's data cable, it is also possible to cause data to interrupt or errors during transmission, which will also cause the machine irregular crash.
(8) Hardware quality or fake goods, and parallel.
The hardware quality is fierce, and the crash will also appear in a long time or when the working environment is too high or too low. Especially some Remark's computer products, there is a problem on your computer, it is best to check it out and can't find the problem. At this time, it is best to consider whether it is bought by JS. There are 40G hard drives in 40g of cool fish a few hours, and I have a bad track. Then Format is normal, but the fault has appeared again after a period of time, and then getting more serious, sometimes Ming Ming Data.
(9) Accidental damage
We did not vent the static or lightning currents in the repair process, which entered the host, damaged the power, motherboard, MODEM, and various internal equipment through unprotected power and MODEM telephone lines. After the accident is damaged, there is no obvious burning, crack mark, which can only be used to test the good and bad of the host components by the exchange method.
(10) Interference
There are many household appliances, especially inverter air conditioners, washing machines, and induction cookers. These electrical appliances will take a lot of electromagnetic waves in the air, if the computer is nearby, then there may be inexplicable crash or blue screen phenomenon . At this time, we'd better try the computer to try a place.
(11) Memory damage or is not compatible
When there is a bad block inside the memory or when compatible with the motherboard, it will also appear frequently: registry error, memory error, blue screen, system resources, and then crash.
The current features of the current host are more convenient, such as keyboard boot, password boot, STR, etc. As everyone knows, the more features, the greater the possibility of failure. Especially the STR function, when the function of the machine is turned on, when we choose to sleep, then the system saves the current setting in memory, then turn off the circuit of other parts, only sub-power work and memory related circuit work. . During sleep, the memory is constantly refresh, where the content will not be lost. However, if the power of each memory is about 20W, when the power of each memory is about 20W, it will cause too much heat accumulation, and it can't go out. Finally, the host power supply or memory is burned. 2. software
Software causes a lot of failures of crashes, such as viruses, drivers installation errors, drivers and systems or other software conflicts, CMOS settings errors, config.sys, or autoexec.bat configurations, win.ini or system.ini file loading The file is lost or destroyed, the loaded program is too large, and the system remaining resources is too small.
(1) virus
Generally manifestation is that the machine can run normally. Sudden running speed at a certain day, there is frequent crash. At this time, we must first use the latest anti-virus software to make anti-virus, determine if the machine has been infected with the virus. The current computer virus is uneven, and most of the communication methods tend to spread through the network, so we must install network anti-virus software when online, and close some open unopened ports.
(2) Driver installation error
Hardware driver installation errors or hardware self-drivers are bugs, causing crash phenomena, and if you need to check if the driver of the installed hardware matches the hardware model or core chip model. If you can download the latest hardware driver.
(3) CMOS setting error
CMOS's content such as CPU frequency, frequency, memory refresh time, L1, L2 open, ECC check or e-quotation, 15-16m, etc., the above content is set, and the computational speed of the host will be significantly changed. Slow, finally crash. When the "Anti Virus" or "Virus Warnning" virus protection feature in the CMOS setting is turned on, we will generate a crash during the installation of the Win9x software, because the system prevents the program from booting the main boot area and C drive boot. Write operation instructions in the area.
Due to frequent modification of CMOS parameters, or viruses damage to CMOS parameters, it often causes the CMOS parameter chaos and difficult to recover. The method of discharging CMOS is used and the system BIOS default setting value can be reset to the CMOS parameter. The discharge method of CMOS can be carried out with reference to the board instructions. After resetting the CMOS parameters, you must also anticorate the hard disk.
The default settings can be taken to CMOS, such as "Load Setup default" and "Load Bios Default"; (4) config.sys or autoexec.bat file configuration is incorrect
If it is restarted after a software installed during the software installation, it is generally unmatched with some configurations of the system with the installed software. At this time, you can try to modify the related driver settings in config.sys and autoexec.bat.
You can also press F5 to skip the system profile at startup or press F8 to select an option in config.sys and autoexec.bat to check for a certain driver or loading file, especially Is the configuration of EMM386 on the configuration of EMS, XMS, we can tell the cause of the fault;
Some hardware drivers and memory resident processes can avoid conflicts by doing of their methods without loading them.
For Win9X operating systems, support for the above two files can no longer start the system normally, the two files are mainly supported and compatible with the original DOS program.
(5) The files that need to be loaded in Win.ini and System.ini files are lost or destroyed.
If the files that need to be loaded in Win.ini and System.ini are destroyed or lost, there will be only a flashing of only the light-saving time during the system startup, the keyboard, and mouse has no reaction. However, most of the appearance is that a file cannot be found. At this time we can retrieve the file according to the prompt or delete the corresponding option in the WIN and System files.
If the system cannot start after a start-up, we can use the scanreg / restore command to recover a registry test for a certain day.
(6) Software has conflicts or incompatible
As the applicability of the operating system is more convenient, its programs and instructions are increasing, and different software is inevitably conflictless. Sometimes the initial version of the anti-virus software may have a small bug when designing, so when the user is installed, the host cannot shut down, the system starts slow, the blue screen crash and other issues. At this time, we can close or unload the software. The criterion of judgment is that if the system works normally when installing a software, the system is not normal after the software is installed, then the problem is definitely caused by the software.
(7) The loaded program is too large or too small system resources.
If the host configuration is too low or the start-up application is too large, it will also generate a crash. At this time, you can select "Users yourself to specify virtual memory settings" in my computer properties, and increase system virtual memory twice or more. The main method of solving is or select the appropriate application based on the configuration of the machine.
(8) Network problem
Sometimes the network will also cause crazy phenomenon. Now popular Lianzhong, legendary online games, if the network is not normal, will also generate crash in the process of communication with the server. Some are degraded in the internet process, and some are degraded after the drop. three. Solution to the basic principle of computer failure: Soft hard, first outside, then the primary is from, the smallest system is replaced one by one.
four. for example
(1) A Lenovo PII400 host, starting the start speed after installing Rising anti-virus software. Open an application, such as WPS2000, take 30 minutes. Carefully test, not only open the application software, and print a A4 paper when printing a document using the printer, and also spends near 10 minutes. After analyzing the presence of the fault, finally, after uninstalling the Rising anti-virus software, the system returned to normal.
This year, the new listing of **** 2003 anti-virus software also has unstable and incompatible situations. Blood screen or crash will often occur after installation.
When we installed anti-virus software, it is best to complete the application software, and finally install anti-virus software to minimize incompatible or conflict.
(2) A PIII800 host, using a small compact chassis, in July, August every year, often suddenly shut down, and turn it off. The power is pulled down after a few seconds, and then boots to boot. This kind of fault is mainly because the chassis is small, the internal space is narrow, and after more than a year, there is too much dust, the air flow is not smooth, causing the main board, CPU, and power generation, and finally cause power protection or crash. . Finally, open the chassis, troubleshooting the CPU and the power supply after dust removal.
(3) A CII566 host, just installed in the computer company, a blue-screen dead machine in the customer's office. This issue has been going back and forth from the company to the customer. It is in the company's normal, and it will be dead in the office of the customer. Finally, the inspection found that the above computer is a working air conditioner. Finally, after moving the computer from the air conditioner, troubleshooting.
(4) A PIV2.0 machine, the customer just bought home for two days, after three hours of sleep, no matter how to press the keyboard, the mouse cannot wake up. This problem is mainly to open the STR function in the CMOS settings inadvertently (set to S3), and then use sleep, resulting in overheating of the power supply. Finally replace the power failure resolution.
(5) A P166G brain, after installing RealPlay, the system prompts to restart, and there is no response after the blue sky is white. This problem may be that the software installed on the 166mmx machine has a conflict with the RealPlay software or the file required by the RealPlay software, causing a crash in the startup. Finally, enter the security mode, after uninstalling RealPlay, you can start normally. Looking for crash faults "true"
The CPU can be said to be the most sophisticated hardware in the computer, in the small body, protecting millions of transistors. Therefore, it is also stricter for its requirements for the work environment.
Computer users will have this experience. After using a period of time, it will appear very noise when booting. If the computer is placed in a dusty room, this problem is more prominent. In this phenomenon, most users have taken a plain attitude, although the sound is large, but it does not affect the normal operation, and general noise will weaken after a while. The generation of noise is due to the CPU or the power supply fan accumulated too much dust. It must be noted that such problems may also affect the normal operation of the machine, and the examples of the fan are also more common. A few days ago, my friend called, his machine is always dead, and reloading the operating system cannot solve it. The author has to go to see. Friends' machine configurations are as follows: Celeron 300A CPU / Hap BX motherboard / 128MB modern PC 100 memory / Seagate 20GB hard disk / miscellaneous TNT graphics card. Just started, the smashing noise, the friend explained that this noise has been a period of time. The machine then self-test, read the list of devices, start Windows, everything is normal. Run some small programs in Windows, starting there is no problem, but don't start crashing. Restart the machine and craf in the run. Based on past experience, most of the dead machine is due to the problem of memory, so the author took his memory in the test, and still appeared after a period of time. So turning his eyes to the hard disk, given that the hard drive of Seagate is large, with a fan direct blowing hard drive to cool down, the result is still still. At this time, the author feels that there may be problems in the system itself, and the system maintenance is not good, causing system confusion. Reinstall Windows 98, still crash after successfully installation.
It seems that the problem is likely to happen on the CPU. Is it because the CPU overheated crash? The author started the machine first, run for a while, then contact the surface of the CPU after shutting down, found that it is only a signs of overheating. The author changed his CPU to a friend's motherboard, and there was no problem for a long time. Is it difficult to be a friend's CPU? Put his CPU to my machine, there is no problem, it is really strange. Suddenly, the author thought that because the friend's CPU fan noise is too big, the author has been using his CPU fan when testing, will it be a fan? Drain the fan's fan dust, clean it, oil, reload, the noise of the 没有, the fault has disappeared.
Current consideration, the reason why it is considered to be crafted, because the fan dust is too much, it interferes with normal operation, which will greatly reduce the fan speed, affect the cooling effect, so that the memory or CPU does not work properly, will have a crash situation. Therefore, don't underestimate small dust, sometimes they will also lead to a big problem. Win XP "crash" also played personality
Friends using a Windows XP system, the chance of computer crash is greatly reduced than before, but due to various reasons, the computer sometimes does not respond, and the same crash. In fact, the computer is not really crash, but is in a state of a false death. The inspection method is: Press the Num Lock button in the digital zone. If the indicator is reactive, it will explain it is a fake. At this time, we can press the "Ctrl Alt Del" key key to perform "End Task" in the Windows Task Manager. However, sometimes this trick is not very spiritual, although "close ..." prompt box, the system will still have no response for a long time. Can you give a personalized setting, let the "crash" become smart, fast? Come with me.
Enter "RegeDit" in "Start → Run" to open the Registry Editor, and make the registry as follows:
1. Set the wait time at the time of the program Open "HKEY_CURRENT_USERCONTROL PANELDESKTOP", find "HungappTimeout" in the window on the right, modify the key value to 2000, unit is millisecond.
2. Accelerate the shutdown application
Open "HKEY_CURRENT_USERCONTROL PANELDESKTOP", find "WaitTokillApptimeout" on the window, change the key value to 10000, and unit is milliseconds.
3. Allow forced shutdown
Open "Heky_USERS.DEFAULTCONTROL PANELDESKTOP", find "autoeeendtasks" on the window, and modify the key value to 1.
4. Automatic restart when system crash
Open "HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETCONTROLCRASHCONTROL", "Autoreboot" is found in the window on the right, and the key value is modified to 1.
After the above modifications, you will find that the system has become smart when "crash".
