How to deal with computer failures? How to deal with computer failures

There are three reasons why the fan noise is high, one is that when the CPU is working too much, the fan noise will suddenly become louder. The second is that because the fan has been bought for a long time, it will make a lot of noise, and the third is that there is too much dust, and it will also make a lot of noise. Your computer will not work properly, which may fall into the third situation.

Dust blocks the heat dissipation of the fan, and if the CPU operating temperature is too high, it will not work properly. You open the case and touch the aluminum plate of the CPU fan with your hand to see if it is hot.

If your computer doesn't even display English on it now, then you open the lid of the main unit, take off the memory and wipe the gold finger on the memory with an eraser, and make sure to put the memory on at the time of installation. The reason why the sound of your computer's fan is loud when it is turned on is because the power supplied to the fan by the motherboard is 12V when the computer is turned on, and when the sound is low, the voltage drops to 5V. When the voltage is high, the fan will rotate fast, and when the voltage is low, the sound will be loud, and the sound will be slow when it is low, so the sound will be reduced.

Even if you change the fan for a long time, it will still be like this, as long as there is a sound, it means that the fan is rotating, and the fan is rotating, it means that the heat dissipation is mostly fine. I hope it can help you, if you want no sound at all, spend more than 100 two hundred to buy a Silent King fan! My QQ is:

Let's take a look at a new fan, it may be that the fan has been used for a long time.

It's normal for your computer to be loud and then loud all of a sudden, and you mean the monitor isn't showing, right?

You take the motherboard's battery off and put it on in 2 minutes and see! ~
