There is a screeching mosquito sound inside the computer case

Normally, it's just that the sound level of different motherboards is different. It's almost a big brand, but most people don't pay attention to it It's a high-frequency sound, especially when there is a large amount of data processing, especially when there is a lot of data processing, especially the Internet café without a disk. You can lean your ear over and listen to the sound that is most noticeable at the moment when the PXE is guided.

There are also some people's monitors that have this problem, and the early flat monitors sometimes emit high-frequency sounds, but it doesn't matter if you move the mouse, the monitor is mainly the sound from the inductor near the CPU on the motherboard. This problem is not very big, if you feel that the sound is too uncomfortable, change to a better board, and the power supply is not good will also indirectly lead to this situation, many people, endure and get used to it, and the general case is better than the one can not be heard.

The only things that can sound inside the case are the fan and the hard drive:

1. If you touch the case, you don't feel an obvious vibration, if there is, one of the fans in the case is broken.

2. If the fan is not broken, it is a hard disk. The hard disk has bad sectors or other problems, it will make a very sharp sound, as soon as it is turned on, it is like an airplane is about to take off, the sound is small to large, and when it is shut down, it is like turning off the engine, this kind of problem will occur on the old hard disk. If you hear this kind of sound, it's best to buy a hard drive first and back up the files that are not in it, if you use it until it is broken and cannot be moved, it will be too late.

Normal phenomenon,As long as you usually watch TV, it's fine,It's the current sound of the high-voltage package,Not only TV,The monitor has this phenomenon,It's okay。

You're talking about a relatively high-frequency sound, and you can't tell what position it is.

Is this sound similar to the sound of communication? It's like the sound of an old-fashioned electric light ballast. This is called electronic whine, and it is caused by your power supply and hardware power, and sometimes even a new computer will have this sound.

If the old machine didn't have it, and now there is this sound, you'd better check your power supply, this does not affect the use, but it may be that some circuits are aging.

The first is whether the motherboard is short-circuited.

The second is that the memory is going to be replaced.

The third is that the hard disk is going to be replaced.

The fourth is that the host does not dissipate heat.

Hope it helps.

Is the motherboard short-circuited. If it's particularly terrifying, it will burn off when it's serious.

The mosquito body also has a certain electrical conductivity, and if the mosquito lands on the two electrodes on the motherboard when the motherboard is energized, it may theoretically cause a short circuit and cause the motherboard to burn out. But in fact, this is relatively unlikely. So, the mosquito got into the chassis and there was basically no problem.

The possibility of mosquitoes flying to the CPU is 0, and it has no effect on the fan, so rest assured! And, computers are more like people than people, and I guess mosquitoes prefer people buzzing buzzing.

Mosquitoes are conductors of electricity, haha, if you don't do it well, you will short-circuit and burn your motherboard.

Your PC has more features than ours.

Mosquito repellent...

It shouldn't be a big deal.

Unless, of course, he hangs.

Or was it electrocuted on the board, right??

Shutdown. After removing the graphics card and memory from the motherboard, gently wipe their "golden fingers" with an eraser, and then put them back on the motherboard.

2 motherboards at home are turned on, in order to have a good heat dissipation effect, there are many mosquitoes at home, but there is no problem at all for 4 years.

And this kind of thing. It's very hot inside the case, a small mosquito can't fly in at all, and flies won't get in.

Classification and processing. Mosquitoes with blood in their stomachs are harmful. If there is no blood, go to the dead. But usually those with blood are fine.

No, it's fine. Just clean it up after a while.

Not necessarily, probably, or not.

Mosquitoes will fly in, but it doesn't matter much, as long as you clean it up regularly.

Generally not, it's very hot in the host, and mosquitoes fly in and burn to death. But still have to clean up the case more!

Absolutely. It's better to seal it up. Reduce the incidence of failures.

It will definitely fly in, and it is possible that it will fly in and not be able to get out.

Will fly in. But never stay inside.

When the chassis is turned off, mosquitoes can enter through the air vent of the electric fan, which is also possible.

Definitely, I've heard of cockroaches living in TV sets before!
