Why does the computer make a strange noise, and the computer suddenly makes a sound

What you hear is the sound of the hard drive.

Generally, if the computer reads a large number of data in the hard disk, the hard disk with poor quality or unstable voltage will make this sound, refresh the desktop, it is introduced in many materials, it not only can not save computer resources, but increase the burden on the computer, its role is only that the refresh rate of the old computer desktop is not high, there will be some images and other residues on the display screen, at this time, the refresh function can remove these visual obstacles, but now the refresh is almost just a decoration.

You may now be due to the case power supply can not be very good to face the phenomenon of sudden large data throughput of the hard disk, can get a better quality power supply to the best, if not, it will be the same, it will not be a bad disk sector.

It doesn't matter.,You can use Everything is normal.,If you feel uncomfortable.,You can check it.,No, I have to determine what kind of sound it is.,It's been very clear above Anyway, it's not a memory problem.

You're listening carefully, and the sound is coming from the place where the explanation is.

I think if it's a network card, it's probably the sound of the network cable jack.

It could also be that the hard drive has bad sectors.

It should be the sound of the hard disk, clean up the disk fragments, a little sound is fine.

See if the cooling fan is loose If so, tighten the screws!!

If you want to use two memories together,It's best to use the same shape number and the same size,Most of you will be incompatible,If the sound comes out of the case speaker,That's basically right,I guess you can also tell whether the sound from the case speaker or the hard disk comes out,

It may be that the inner size is incompatible, it is recommended to try it with a memory!!

There are several reasons for this:

2. It may be radio wave interference, and you can keep mobile phones, radios and other devices that send and receive unlimited signals or have strong magnetism away from the computer.

3. It may be that the communication software, anti-virus software or firewall and other software have sent out an alarm sound, and the sound can be eliminated by changing the settings.

4. It may be that there is dust in the computer fan, so you can disassemble Zheng Zhiyun and turn on the computer to brush the fan.

5. It may be that the screws are loose, just re-tighten the screws.
