Why does a desktop computer have a hey hey sound when it is turned on, how to deal with it?

Haha, maybe this is someone else's specialty.

Problem analysis: The noise you hear is usually caused by the internal fans of the console, including the power supply, CPU, and graphics card fans. Because of the cold weather, the effectiveness of the lubricant inside the fan decreases, and there is more dust, the running speed of the fan decreases, and the friction increases.

If the noise resonates with the chassis frame, not only the loud noise but the entire chassis will vibrate. After a period of use, the lubricant inside the fan gradually recovers due to frictional heat, and the sound is reduced accordingly. In addition, it is not excluded that the screws inside the case may loosen and cause a loud sound.

Handling suggestions: 1. Dust the fan inside the case, add lubricant, or replace the new fan directly.

2. Tighten the screws on each part of the chassis.

The computer has been used for too long, and it has gone into dust, so clean it up.

The sound of the computer booting up comes from.

Fan. There is a lot of dust, the shaft is loose, the speed of the engine will be uneven, and it will make a sound, and the sound will become smaller after a while.

2。Graphics card fan.

There is a lot of dust, the shaft orange is loose, the speed of the boot will be uneven, it will make a sound, and the sound will become smaller after a while.

3。Power supply fan.

There is a lot of dust, the shaft is loose, the speed of the boot will be uneven, it will make a sound, and the sound will become smaller after turning on the machine.

4。There are discs in the light zone.

When the boot starts, the hardware is detected, and the optical drive will read the disk and there is a sound.

5。The hard disk has been turned for a long time, turning the sound.

or bad tracks after the hard drive, making a creaking sound.

6。Some types of main bridges will have cooling fans.

7。If it's a new machine, see if the CPU fan has the power cord inside hung to the fan blade.

You will know one by one.

You check it.,Open the case cover purely.,After booting up, you hold down the cup fan and the graphics card fan with your hands.,See if it's a mold sail or a hail of pants.,Just replace the fan.,If both are not,That's the power supply fan sounds.。。。

Make sure that the spine of the graphics card fan or the CPU or power supply fan is ringing in the process.

For you to make sure the power supply fan is ringing, follow this.

Turn on the power (be sure to turn it off.)

The voltage is very high and dangerous).It could be heat dissipation, or it could be a normal sound!

Fan problem,It's best to change the sliding code to seep a fan.,It's hot and it's about to be scrapped.,Persuade the landlord to change a machine model.。

If the heat dissipation is not good, ,..

The power supply fan or the fan that comes with the case.

I've also encountered this bureau asking questions or questions.

Unplug the case fan and power connector.

That's it.
