The computer motherboard is broken how to repair

Problem one: no display on boot

Solution: If your computer appears to have no fault on the boot, most of the motherboard BIOS data is missing or damaged. And all we have to do is clear the BIOS, the most common method is to clear the BIOS through the motherboard jumper.

BIOS jumper

Removing the battery and then pressing on can also achieve the purpose of cleaning the BIOS

The BIOS jumper is typically near the lithium battery in the motherboard, its default position is generally 1, 2 short circuit, as long as it is changed to 2, 3 short-circuit a few seconds to solve the problem, for the old motherboard if the jumper can not find, as long as the battery removed and then can be achieved to clear the BIOS.

BIOS except key

With the continuous development of the motherboard industry, many manufacturers in their respective motherboard products have added a lot of very user-friendly design, including a key to the BIOS to clear the keys, some motherboards even the BIOS in addition to the key design to the motherboard I/O interface, even if the case is not open chassis, Users can also easily clear the BIOS.

In addition, for faulty motherboard damage, it may also be because the motherboard with a long battery leakage caused by the circuit board moldy (especially many old motherboards), so that the motherboard can not work properly, so that we could thoroughly clean to see if the problem can be solved, this method also on the motherboard of the contact of the socket bad root of the good.

Cleaning method: Use the tool to unplug the BIOS on the motherboard, the CMOS battery, and then use the hard hair brush, washing powder, the parts of its thorough cleaning, and finally rinse clean with tap water, to the motherboard shade and then try again.

Problem two: Frequent crash/blue screen

Believe that a lot of friends often encounter computer crashes frequently, this situation is likely to be your motherboard or CPU, graphics card out of the question. Such failures are generally caused by poor heat dissipation on the motherboard. I used to use the motherboard before this situation, the CPU around the motherboard components of the temperature is very high, but hot, but after the replacement of high-power fan, the crash can be resolved.

As for the computer blue screen failure, according to the causes can be divided into software and hardware two aspects, here we mainly from the hardware point of view. Generally, because of the hardware causes the computer blue screen mainly has the following kinds of situations:

Blue screen caused by memory overclocking or instability

Ⅰ. A blue screen caused by memory overclocking or instability.

Instance: Random blue screen.

Solution: Use the normal frequency first, if there are any problems. Find a good memory for the failure of the replacement lookup, can generally be resolved. Then you should pay attention to the CPU when the memory is very close to the problem of heat dissipation.

Poor compatibility of hardware caused by blue screen

Ⅱ. A blue screen caused by poor compatibility of hardware.

Instance: When the memory is upgraded, the failure of the different specifications of the memory strips is mixed.

Solution: Note the memory of the manufacturer, memory particles and batch number of differences, often because of the different memory in the main parameters of the difference in the blue screen or panic, or even more serious memory failure. You can also change the slot position in which the memory bar is inserted. If the memory is still not working properly, it has to be replaced. Here, to remind you: memory in the whole computer system plays a very important role, it will directly affect the stability of the system, so in the purchase of memory to pay attention to, it is best to have the company of pedestrians, to avoid buying remark of the sliver or too low frequency of the note.

"Blue screen" fault caused by hardware heat dissipation

Ⅲ. "Blue screen" fault caused by hardware heat dissipation.

Example: In the heat dissipation problems appear on the fault, often have a certain law, the general computer running for a period of time before appearing, performance for the blue screen crash or random restart. The main cause of the failure is the data reading and transmission errors caused by overheating.

Solution: To take overclocking should be reduced frequency, over-temperature should be cooled. In fact, not all of the failures are so complex, sometimes from a simple aspect of consideration, can also be a good solution to the problem  to learn analogy.

All things to nip in the bud, the following is the author summed up some of the experience available for your reference:

1 regularly to the important registry files for manual backup, to avoid system errors, can not be replaced in time to backup files and produce irreparable errors.

2 try to avoid abnormal shutdown, reduce the loss of important files. such as. VxD. DLL files, and so on.

3 for ordinary users, as long as the normal operation, there is no need to upgrade the graphics card, motherboard BIOS and drivers, to avoid the damage caused by upgrades.

4 Reduce the installation of unwanted software, try not to manually uninstall or Remove Programs, to reduce the illegal replacement of files and files point to the error of the occurrence.

5 If the memory is not particularly large and its management program is very good, as far as possible to avoid large programs running at the same time, if you find that listen to MP3 when there is Chachalaras voice, the basic can determine that the fault is caused by insufficient memory.

When the motherboard strikes, there may be a variety of symptoms. What should you do at this point to quickly and efficiently troubleshoot the motherboard? To this end, the author specially for you to complete a number of related failures of the rapid response measures.

One: Why does the motherboard not start normally, while memory emits a beep beep?

Failure Analysis: The possible causes of this phenomenon are: motherboard memory slot, poor performance, the golden finger on the memory bar and the socket reed contact is bad; it may be the gold finger on the memory strip, the surface of the gilded effect is not good, in the long work, gold-plated surface appears a very thick oxide layer, which leads to poor contact with the memory bar; Another possibility is that the production process of the memory bar is not standard, it is a bit thin, so that the memory and slot always have some gaps, a little bit of vibration, it may lead to poor memory contact, triggering alarm phenomenon.

Troubleshooting: Solve this phenomenon, as long as the computer chassis open, and in the case of power off the memory strip, will appear on the memory of the dust or oxide layer, wipe them with the eraser, and then reinsert into the memory slot on it. If the memory is too thin, you can use hot melt glue, the slots on both sides of the small gap to fill up to ensure that the memory is not swayed around, this can also effectively avoid the gold fingers are oxidized. If the above method, can not solve the problem, the replacement of new memory to try; In the case of new memory replacement, the alarm continues to appear, at this time can only replace the motherboard to try.
