Today, the main board is getting higher and higher, and the difficulty of maintenance motherboards is getting bigger and bigger, often need to be done with special digital testing equipment. However, some motherboards do not need special inspection equipment, you can do it yourself, and below is some of the most typical motherboard fault maintenance examples, I hope everyone can solve the basic approach to the motherboard failure.
First, the boot has no display fault
[Example 1]: The motherboard does not start, and there is no display, there is a memory alarm ("嘀嘀" is called a non-stop) Fault: The fault of memory alarm is more common, mainly caused by poor memory contact. For example, the memory bar is not specified, and the memory strip is a bit thin. When the memory is inserted into the memory slot, there is a certain gap; the gold finger process of the memory strip is poor, the surface of the gold finger is poor, the time is long, the gold finger surface oxide layer Gradually thickening, causing poor memory contact; the memory slot is poor, the reed and the gold finger of the memory strip are not true. Treatment: Open the chassis, remove the gold fingers of the memory strip with the eungent, remove the memory strips and re-insert it, and fill the gap between the memory slots to prevent oxidation during use. Note: Be sure to unplug the host folding power line when plugging in the memory module to prevent accidental burning memory.
[Example 2]: The motherboard does not start, the boot is not displayed, there is a graphics card alarm (a long two short tweet) failure: generally the graphics card loose or graphics damage. Treatment method: Open the chassis and re-insert the graphics card. To check if there is a small matter in the AGP slot, otherwise the graphics card cannot be inserted; for the motherboard using the voice alarm, the contents of the voice prompt should be carefully identified, and then solve the corresponding fault according to the content. If the above method is handled, it will also be alarm, it may be the chip of the graphics card, replace or repair the graphics. If you hear the self-test of "嘀" after boot, the monitor is normal but there is no image, put the graphics on other motherboards, use normal, that is, the graphics card is not compatible with the motherboard, should replace the graphics.
[Example 3]: The motherboard does not start, the boot is not displayed, and there is no alarm. There are many reasons. There are many of the following. Treatment: For the following reasons, it is eliminated one by one. Ask you to familiarize yourself with the digital circuit analog circuit, you will use the multimeter, sometimes you need to check the DEBUG card check. (1) Problems in CPU
The CPU is not powered: the three (or one) field tube and three (or one) rectifier diode around the CPU can be used to check if the CPU is damaged. The CPU socket has a pointer or loose: This type of fault is not bright or the dead is not scheduled. Need to open the upper cover of the CPU socket, carefully use your eyes to see if there is a deformable pin. The fan fixation of the CPU socket breaks: Can consider using other fixed methods, generally do not replace the CPU socket, because handwelp is easy to leave a fault hazard. The CPU of the Socket370 is fixed by the CPU socket. If the fixed spring sheet is too tight, it must be cautious when disassembling, otherwise it will cause the plastic clip to break, there is no way to fix the CPU fan. The CPU frequency set in CMOS is not: Solution as long as CMOS is cleared. Clearing the CMOS jumper is generally near the main board, its default location is generally 1, 2 short circuit, as long as it makes it a few seconds to short circuits to solve the problem, for the previous old motherboard, if not To this jumper, just remove the battery, then display the CMOS setting and then shut down, and install the battery to discharge. (2) The motherboard expansion slot or expansion card has problems
Because the motherboard expansion slot or expansion card has problems, after plugging in the graphics card, the sound card, the motherboard does not respond, so there is no display in the boot. For example, the brute force disassemble the AGP graphics card, which causes the AGP slot to crack, which can cause such faults. (3) Problems in memory
The motherboard cannot recognize memory, memory corruption or memory does not match: some old motherboards are relatively picky memory, once inserted with the memory that cannot be identified, the motherboard can not start, even some motherboards have not fault prompt (Ning). Also, if you are inserted with different brands, the type of memory, sometimes such faults can also cause this type. Memory slot breaks or burnouts: Sometimes because improper use of force, the reed deformation in the memory slot can cause the memory slot to be scrapped. Note: When inserting the memory module, it should be vertically, do not shake around. Before plugging in the memory module, be sure to remove the power supply of the host, prevent the memory to charge, burn the memory module when the STR function is used. In addition, the memory should not be installed, so as not to power the memory module. But now the motherboard, usually there is a defense design, and it will not insert it. (4) The motherboard BIOS is destroyed
The BIOS of the motherboard stores important hardware data, and the BIOS is also fragile parts in the motherboard, which is extremely susceptible to damage. Once damage, it will cause the system to operate. Such malfunctions are generally because the motherboard BIOS is damaged by CIH virus. After the BIOS is damaged by the virus, the data in the hard disk will be lost, you can detect whether the hard disk data is intact, in order to determine whether the BIOS is destroyed; if there is a Debug card, you can also pass the BIOS indicator on the card. . When the boot block of the BIOS is not broken, the display is not bright, the PC speaker has a "doodle" alarm; if Boot is destroyed, then the power supply and hard disk light are on, the CPU fan is turning, but does not start At this time, you can only rewrite the BIOS by programmers. You can also plug in the ISA graphics card to see if there is a display (if prompted, you can follow the prompt steps.), If you don't boot screen, you can do an automatic update of the BIOS, re-refresh the BIOS, but After the motherboard BIOS is destroyed, the floppy drive does not work at all, and it is recommended to find a service provider, write the BIOS update file to the BIOS with a writer. (5) When the battery used by CMOS is issued, the hard disk and the power light are on, the CPU fan is turned, but the host does not start. When the battery is removed, it can be started normally. (6) motherboard automatic protection lock
Some motherboards have automatic detection protection functions, and when the power supply voltage has an abnormality, or the CPU overclocking, the adjustment voltage is too high, and the stop is automatically locked. The performance is that the motherboard does not start. At this time, the CMOS can be discharged and then boot, and some motherboards need to hold down the reset key when turning on the motherboard. (7) The capacitance on the motherboard checks whether the capacitance on the motherboard is bubbling or fell. When the electric capacitor is too high or long, it will bubbber or liquid, and the capacity of the capacitance is reduced or lost, the capacitance will lose the filtering function, so that the communication ingredient in the load current is increased. Cause CPU, memory, and related board works are unstable, which is easy to crash or system unstable, often appear blue screen.
[Example 4]: The motherboard temperature control is abnormal, causing the boot without display ASUS P3B-F motherboard to monitor the CPU temperature, with a 2PIN temperature monitor line, plugged in the JTP pin next to the CPU slot. Later, in the process of playing the game, the machine suddenly blue screen, after rebooting, waited until the optical drive, the hard disk was not bright after the hard disk was inspected. Cause: The temperature control line on the motherboard is detached and falls on the motherboard, causing the motherboard to automatically enter the protection state, and refuse to power the power. Since the CPU has a very large amount of heat, many motherboards provide strict temperature monitoring and protection. Generally, the CPU temperature is too high, or the temperature monitoring system on the motherboard has failed, and the motherboard will automatically enter the protection state. Refuse to power boot, or alarm prompt. Treatment: Reconnect the temperature monitoring line, and then turn on. Note that when your motherboard does not start or alarm normally or alarm, check whether the temperature monitoring device of the motherboard is normal.
Second, CMOS fault
[Example 5]: The computer is frequently crafted, and the cause of crash in the CMOS settings will also occur: Generally, the motherboard is not caused by poor heat dissipation or the motherboard Cache has problems. Treatment: If the fault is caused by the hard cooling of the motherboard, you can touch the main board components around the CPU, you will find that its temperature is very hot, after replacing the high power fan, the crash can be resolved. If there is any problem with cache, you can enter the CMOS settings, and you can prohibit the cache. Of course, after Cache is prohibited, the machine speed will definitely be affected. If you still can't resolve the failure in order, there is a problem with the motherboard or CPU, only replacing the motherboard or CPU. [Example 6]: The CMOS parameter is lost, and "cmos batteryst low" is prompted after booting, sometimes it can be started, and the dead after a period of time. Cause: This phenomenon is mostly caused by CMOS power supply. Treatment: If it is a welded battery, you can reload a new battery with the soldering iron; if it is a button battery, you can replace it directly; if it is a chip battery, you can replace this chip, it is best to use The same model chip is replaced. If the battery is replaced, the time does not have the same phenomenon, then it is probably the motherboard leakage, you can check if the diode or capacitor on the motherboard is damaged, or you can use an external battery.
[Example 7]: CMOS settings cannot save troubleshooting: generally due to insufficient main board battery voltage: replace the battery. If there is a motherboard battery replace, you should not solve the problem, you should check if the motherboard CMOS jumper has a problem, sometimes because of the CMOS jumper on the motherboard to clear the option, or set to an external battery, will make CMOS Data cannot be saved. If it is not the reason, it can be judged that the motherboard circuit has problems, it is recommended that you find professional repairs.
[Example 8]: The motherboard anti-virus is not closed, causing the system unable to install the WIN98 initial phase, suddenly a black rectangular area on the screen, like any tips, then stop installed. Adjusting the brightness of the display and the contrast switch is also invalid, killing the virus with anti-virus software, did not find any viruses. Cause: This phenomenon is relatively prone to appear in the new shopping motherboard, because by default, the anti-virus setting in the new motherboard BIOS is most Enabled, so there is a similar fault. Treatment: Read the motherboard manual carefully. Enter the CMOS Setup program, set the "Virus Warning" option in the "BIOS Features Setup" by "Enabled" to "Disabled" (forbidden), you can solve the problem.
Example 9]: When installing Windows or starts Windows, the mouse is not available for an old 586 computer, installing Windows or starting Windows mouse is not available. After replacing the mouse, the fault still cannot rule out. Doubt is the motherboard PS / 2 mouse interface fault, get the professional motherboard detection point to check the PS / 2 mouse mouth is normal. Cause: The IRQ setting error is caused in the CMOS parameter. Such faults are often found in old-fashioned 586 computers, and new motherboards generally do not have this issue. Treatment method: In the power management bar set in CMOS, there is a MODEM USE IRQ project, and the options are 3, 4, 5 ..., NA, and generally its default options 3, set it to 3 Interrupt items can be excluded. In addition, some old-fashioned 586 computers, the COM port and the LPT port is connected to the chassis by a signal cable. The next method of the signal line is different from the motherboard. If the connection is not aligned, the mouse is not available. The next method generally has the following two: (1) The signal line is connected to the connecting head according to the order of 1 to 9; (2) the signal line is connected to the connection point, and the connecting head is connected to the signal line 1, 3, respectively. 5, 7, 9, one row below 2, 4, 6, 8. [Example 5]: The computer is frequently crafted, and the cause of crash in the CMOS settings will also occur: Generally, the motherboard is not caused by poor heat dissipation or the motherboard Cache has problems. Treatment: If the fault is caused by the hard cooling of the motherboard, you can touch the main board components around the CPU, you will find that its temperature is very hot, after replacing the high power fan, the crash can be resolved.

[Example 10]: Cache damaged on the motherboard Cache damage on the motherboard, manifested to run software crash or unloaded software. Treatment: You can troubleshoot the "External Cache" item to "disable" in the CMOS settings.
Third, I / O equipment is not working properly
[Example 11]: Motherboard COM port or parallel port, IDE port failure causes: generally due to user charging and detached hardware. Treatment method: Can be replaced with multi-function cards. But before replacing, you must first prohibit the com ports and parallel ports on the motherboard. Note that the motherboard has been banned, and it can be used normally.
[Example 12]: When the keyboard interface on the motherboard cannot use a good keyboard, when it is turned on, the "Keyboard Interface Error" appears, unplug the keyboard, and re-insert it, it will start the system normally, use a period of time after using the keyboard No reaction. Cause: Pull the keyboard multiple times, causing the motherboard keyboard interface. Treatment: Remove the motherboard to reload the soldering iron. If it is an electric plug-in keyboard, it causes an insurance electrical block on the motherboard (tagged as FN on the motherboard), replacing a 1 ohm / 0.5 watt resistance.
[Example 13]: The display adapter fault to integrates on the motherboard has a Great Wall microcomputer, which is started with 8 sounds, and it is determined that the display adapter fault. Open the chassis found that the adapter is integrated on the motherboard and there is no motherboard manual. Cause: A few sounds after boot, most of which is that the memory memory is not plugged or displays the adapter failure. Treatment: Carefully view the jumper marking on the motherboard to block the display device integrated on the motherboard, and some motherboards need to disable the syndrome on the motherboard through the CMOS settings; then in the extended slot. [Example 14]: The printer on the motherboard parallel 486 microcomputer, and the printer is mostly integrated on the motherboard, which is easy to print. Fault: With an electric plug-in printer signal cable, it is most likely to cause corruption damage to the front of the motherboard. Treatment: Check if the printer supports DOS printing, in pure DOS state, use Dir> PRN (only valid for the needle printer and part of the laser, the inkjet printer), see if the print is normal; view the motherboard manual, through "prohibited or allowed or allowed Parallel feature "related jumper on the motherboard, set the parallel port function on the" shield "motherboard (or shield via CMOS settings), and then add a multi-function card in the ISA expansion slot.
[Example 15]: Mainboard Soft / Hard Disk Controller Cause: Starting from 486, most motherboards integrate soft / hard disk controller, most controller damage is caused by electricity plug. Treatment method: Treat it separately for the following conditions. (1) The floppy controller can change the board on the motherboard or CMOS settings, and add a multi-function card to get it. (2) If the hard disk controller is bad, if the hard drive is less than 528MB, you can add a multi-function card; if the hard drive is greater than 528MB, you need to update the motherboard BIOS, or use the related software.
[Example 16]: IDE wiring error, can not find a 40GB host of the hard disk, re-connect the primary hard disk and turn it on a double-hard disk, the machine prompt does not find any IDE equipment, can not find the hard disk and cannot enter WinXP . After restarting into the CMOS setup program, it is found that no IDE device is detected, and the other hard disk is not detected. Cause: This type of failure often occurs. If it is not damaged by the hard disk itself, the IDE line of the motherboard or the IDE is damaged, which can cause such a fault. In addition, when hanging hard drives, similar situations will occur if they do not change the jumper in time. Investigation This example is caused by an IDE wiring error, and the SLAVE port of the ATA / 100 hard drive is connected to the hard disk. Treatment method: Replace it to the master interface.
Fourth, power failure
[Example 17]: After the power switch or reset button is broken, it will automatically shut down for a few seconds. Cause: There is a lot of switches and indicators, headphone sockets on many chassis, and the quality of the USB socket is too bad. If the reset button is still playing, then when power is applied, because the host is always in the reset state, then press the power switch, the host does not respond, and the power light is not powered by power, so the power light and the hard disk light are not bright, CPU The fan is not turned. Treatment: Open the chassis, fix the power switch or reset button. The power supply on the motherboard is more switching power supply, the power tube used is a separation device, if it is damaged, as long as the power tube, capacitance, etc. can be replaced.
[Example 18]: The power supply socket has false, loose, this situation is rare, and it will restart from time to time. Treatment method: When checking, you can sway the power cord of each interface portion in the power-on state, see if there is a failure. [Example 19]: Insurance resistors on the motherboard can't find the keyboard mouse, the USB mobile device cannot be used. Cause: The insurance resistance on the motherboard is blown. Treatment method: The method of discrimination is also simple, and its interworking is measured using the resistive file of the multimeter. If the insurance resistor is fed, the resistance of about 0.5OHM can be used instead.
[Example 20]: The power supply is not enough to configure the NFORCE2 motherboard, Athlon XP 1700 (overclocking to 2400 ) CPU, each boot always presses a few "Power" keys to light up the computer, sometimes it is still detection When the hard disk is stagnant, restart once can usually solve the problem. Cause: The power of Athlon XP 2400 has reached 70W, and the NFORCE2 motherboard's circuit design is very high. Treatment method: Replace the high-power power supply of a brand-name, you can troubleshoot. Inferior power supplies, the chassis will cause great harm to each accessories of the computer. Suggested the players of the NFORCE2 motherboard, prepare a 300 ~ 350W brand (such as the Great Wall, Big Buffalo, Hangjia, etc.).
V. Hardware compatibility failure
