There is something wrong with this computer. Have colleagues from other departments call the computer repairman. He asked me if the computer had been repaired. Does it work? I said fine, and I said thank you. Sure, thank you.

Two days ago, a friend called for advice, saying that when his computer was turned on, the fan was turned on for a few seconds, then turned off automatically, and then turned on automatically, so it was turned on repeatedly, but it could not be turned on all the time, and the display showed nothing. He removed the memory, graphics card and CPU and wiped them with an eraser, but it never solved the problem. He was depressed and suspected that the motherboard was broken.

Such a problem description should be obvious to experienced veterans, but it is a huge problem for novices. I really want to use the computer here, but I can't open it there. Really anxious! So what is the problem with this computer failure and how can we solve it?

Generally speaking, the shutdown of the computer after starting is caused by poor contact of computer hardware, short circuit of the motherboard or subsequent hardware, power failure and other reasons. In case of such a problem, clean the inside of the chassis first, blow the dust clean with the chassis blower, and then wipe the gold finger of the graphics card and memory as mentioned above. If the problem cannot be solved, it must be the following reasons.

The host mentioned above is turned on repeatedly for this reason. The motherboard BIOS error fault will cause the host to fail to boot. We can try to restore the BIOS settings to the factory settings. We will remove button cell from the motherboard, leave it for a few minutes, and then put button cell back in its original position to restore the BIOS initial value. If it still doesn't work after reinstallation, it means that there is no electricity in button cell, and you need to replace it with a new button cell.

First, we open the chassis, and we can see the button cell on the motherboard. Sometimes the battery may be blocked by the discrete graphics card, so we need to remove the discrete graphics card to get the battery.

There is a tenon on the CMOS battery holder to fix the battery. We can press the tenon with a screwdriver or directly by hand. If the tenon is broken, the motherboard button cell will automatically pop up. Then install a new battery. It's simple.

I hope it can help you solve the problem.
