Editor to share with you how to maintain the win8 computer motherboard, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

What are the faults caused by the computer motherboard?

1. The switching power supply on the motherboard is damaged

Most of the power supply on the computer motherboard is the switching power supply of the computer, so its power tube is a separate part, if it is damaged, it only needs a slippery power tube or capacitor.

two。 Keyboard interface on motherboard cannot be used

If the computer is connected to the keyboard, in the boot self-test, prompt "keyboard interface error", after the direct crash, and then re-insert the keyboard can be used normally, after a period of time can not be used, this is mainly due to several times to plug the keyboard rescue, resulting in the motherboard interface loose, we need to remove the host, the motherboard interface on the line.

3. The soft and hard disk controllers on the motherboard are damaged

Usually the motherboard computer motherboard has a soft and hard disk controller, if the floppy disk controller is damaged, you can add a function card, or multiple CMOS reset, if there is a problem with the hard disk controller, in addition to adding function cards, you can also update the BIOS of the computer motherboard.

4. Display adapter failure integrated on motherboard

If there is a sound when you turn on the computer, it should be that the memory of the motherboard is not plugged in, or there is a problem with the adapter of the display screen. In this case, you need to carefully observe the jumper on the motherboard. You can first shield the integrated display device on the computer motherboard, and then insert the video card on the expansion slot to slowly troubleshoot.

How to repair if the computer motherboard is broken?

1. Let's take apart the chassis, remove the screws from the computer motherboard and remove the motherboard. This is convenient for us to repair, if it is confirmed that it is the motherboard problem and then dismantle. Be sure to turn on the phone before you open it and see what's going on! Don't dismantle the problem that is not the motherboard.

two。 Generally speaking, the motherboard is not so easy to break. After we remove the motherboard, do not immediately take the multimeter to check the circuit. It should be cleaned up with a brush and alcohol. And then put it on the workbench to analyze the specific reasons!

3. When you put it on the workbench, you must have a foam board or a book under the motherboard. This is to prevent the surrounding broken metal, and then when we light the motherboard, cause a short circuit and burn out the motherboard.

4. Fault identification:

(1) whether the capacitor has drum bag and liquid leakage. This means that the capacitance is broken, and the capacitance is even worse.

(2) the multimeter is also used to measure the patch resistance and whether the patch capacitance is damaged.

(3) if it is a black screen, a blurred screen, always rebooting, and a blue screen, this situation is generally related to the components on the plug-in on the motherboard. We can use the replacement method to try a new one to see if it is broken, and then judge whether the motherboard is malfunctioning.
