The computer squeaks 90 when it turns on, and the computer squeaks when it turns on

First, determine whether the sound is coming from inside the display or from the speaker.

If it comes from the speaker, it is likely to be the sound of electricity, try to turn down the volume of the speaker to see if there will still be the sound you are talking about, which is generally caused by interference.

If it comes from the monitor, I don't know what the weather is like over there, but if the monitor is wet, it will make a squeaky high-frequency sound. It is also possible that there is a problem inside the monitor, so it is recommended to contact the dealer to confirm.

The problem with the hard disk is sometimes the LZ hard drive, if it has been used for more than 3 years, it should be checked for bad sectors.

Just having sound can also explain that if the mouse can't move, you can't just judge that it's a display problem.

If the hard disk check is fine, it is estimated that there is a virus to kill it.

Are you saying that the display has sound? When I first bought the computer, I also found that the display screen had a sound, I can't say whether it was a squeak or a Didi, and the maintenance staff came and said, how can the display have a sound, impossible. Later, there was no sound, and I didn't investigate it again, but I found this sound again a while ago, and listened carefully, it came from the speaker, and I didn't care about it.

Hehe! Same as the day before yesterday.

It's a dust killer high.

Good computer hygiene is OK

Try changing the refresh rate of your monitor.

Is it squeaking or beeping??

My computer used to be ticking, haven't you used it for too long? Still haven't plugged in properly? Or into the virus.

It's best to find a professional maintenance person, there is really no way to reinstall the system, no trouble, you can find a colleague who is slightly proficient in the computer to help reinstall.

Sound and mouse should be two glitches.

The sound may be coming from the fan inside the case, which can be alleviated by just cleaning it.

The mouse may be photoelectric and sometimes run around, so try putting a mouse pad.

Although I haven't encountered your situation, I think there should be a hardware problem, so I recommend going to the place where the computer is sold to check it out. If you haven't seen a situation like yours, I'm afraid no one will know about it, so go check it out.

This happened to me in my house, but the system was a bit busy and it wasn't a big deal.

1. The screws in the chassis are loose and make a noise, tighten the screws;

2. Chassis plug-in. The data cable is loose and vibrating, so recheck all the plug-ins in the case and plug it in tightly.

3. If the fan is short of oil, add a few drops of lubricating oil;

4. The sound emitted by the hard disk when reading data, there are too many startup items when the machine is turned on, and some startup items that are not commonly used can be turned off.

5. Is there a disc in the optical drive that has not been taken out?
