How to keep it from making Weng Ning s sound from my computer power box

This is the sound of the fan inside the power supply. You can only ask someone to change the fan or add controllable controls to reduce noise, but you can't really be silent.

If it is a new computer, it proves that the power quality is not up to par, and there is no way but to replace the ultra-quiet power supply! If it is an old one that becomes louder later, you can do dust cleaning and dust removal and turn on the power. This can reduce the bath to a certain extent! Thank you, I hope I can help you, give me satisfaction!

Clean the ash and oil the fan! Don't let the fan spin when blowing.

There will be no sound from the computer power supply, the sound of the main chassis is a fan, it should be a dirty fan, just open the main chassis and blow it clean with a hair dryer.

The quality of the high-frequency transformer is problematic, and the core bonding is not tight. It may be caused by a change in temperature, a shrinkage of the magnetic core. This problem can affect the instability of the power supply voltage output, as long as it is not too severe and does not affect the use.

But the biggest problem is that the sound can be boring and it can be troublesome to repair. So you can consider changing the power supply.

It is caused by the fan of the power supply is not very good, generally a good power supply will not have similar problems, if it is an old power supply, and you are a DIY friend, it is recommended that you disassemble the power supply, replace the fan inside, now it is generally 12cm.

It's a power quality problem that doesn't happen if you change to a high-end power supply.

It is recommended to pad a soft pad, and if the power supply is poor, the fan will be inferior.

Did you change the power supply fan yourself? It didn't sound until more than ten hours later, that is the reason for the heat dissipation part, it is estimated that it was too dirty before, resulting in sweat or poor contact! It's hard to say what kind of sound you haven't heard, but you can rule out the new fan, but it also depends on whether your screws are good.

Then there is the transformer and transistor, the field effect transistor will make a sound if it is too hot, but it is generally inaudible. You can take a picture of the case to see if there is any change, if there is, the fan or power supply is not installed!

It's generally a fan problem. It's up to you to change it or not.

Are you sure it's the power supply? And not the hard drive?

It should be that the memory and the motherboard are not compatible, and another is that if you let the machine suddenly lose power, it retains some electricity, but some machine motherboards have a function that you said to turn off the power socket, turn on the power or the computer will start when the power is turned on!!

Is the display cable connected? Unplug the memory and turn it on to see if there is an alarm sound, if there is a problem with the graphics card, if it is not possible that there is a problem with the memory or the slot of the motherboard.

Turn off the power, turn on the power, and turn on the computer once and it will be successful.

This condition is mostly caused by poor hardware contact.

Nope"Drops"Yes, the motherboard does not have a self-test.

Remove the motherboard battery, short circuit discharge, CMOS

Also, upgrade the BIOS of the motherboard

First of all, you have to check whether the power switch button of your case is glued to the key, and whether the cable is connected properly.

It is recommended that you boot the BIOS and press F5 to restore the reset, it is also possible that your BIOS power management settings are wrong

Bad contact you see for yourself.

Take the power supply apart and add some lubrication.

It's very simple to brush the plaster yourself and apply the oil.

That's because the computer has just opened, and some programs need to be rectified for a while, so don't pay attention to him.
