There is noise when the computer is turned on, and why is there noise on the host unit when the comp

This sound is the sound of the fan, when it is just started, the lubricating oil in the fan is not completely melted, and it will produce noise, and when the operation is stable, it will be fine.

It's like having to plug in a power supply in a damp place. The role of microcurrents.

It's good if you change the fan. Don't know if you're talking about power supply fan noise or CPU fan noise. You can change the specific situation.

It means that your fan is aging, and it is best to replace one in time.

In fact, computers, like cars, need to be warmed up and cooled down.

The old machine is like this, and the broken machine at home is like this, so I'm used to it. If you have the funds, you can change them.

Reasons: 1. There is too much dust in the fan or power supply fan at the ** processor of the computer, and the friction is large, so it makes noise. The dust in the fan should be cleaned in time, or the fan should be replaced.

2. There is grease on the surface of the computer fan, when the computer is just turned on, the temperature is low, the viscosity of the grease is large, the friction is large, and the noise is generated.

3. The computer optical drive has a disc, and the optical disc will produce noise. In the case of not using the disc, the disc should be removed in time, and the startup noise will be reduced accordingly.

4. Hardware failure, hardware failure causes computer vibration. Check that the hard drive is tightened to avoid excessive vibration.

1. The first thing that comes to mind is the fan of the power supply, because it is one of the main sources of computer noise, the computer will accumulate a lot of dust on the power supply fan in the case of long-term use, I believe that many friends have a deep understanding that a lot of dust will naturally affect the operation of the fan, resulting in noise, if it is the noise generated by this reason, as long as the dust on the fan is cleaned up.

2. In addition to the power supply, there is another place where the fan will be used, and that is the CPU. Like the power supply fan, the CPU fan is also a place where it is easy to accumulate dust, and the situation may be more serious than the dust accumulation of the fan, at this time, you can open the box, remove the CPU fan, and then clean it, if the CPU fan causes the startup noise, it will be reduced or even disappear after cleaning.

3. In addition to the power supply and CPU, the graphics card of some computers is also equipped with a fan, which is also listed as one of the most noisy fans, and the same as other fans, it needs to be disassembled and cleaned to remove the dust inside, so as to eliminate the possibility of boot noise caused by the graphics card fan.

It's not a problem, under normal circumstances, noise is a problematic performance, either the fan shaft is derailed or out of place, it is recommended to replace, if it is a CPU fan, change it to a 45-60 price between it, if it is a graphics card fan, 10-20 yuan, Nanqiao fan, 10 yuan.

Recently, many of my friends have heard the computer buzzing as soon as they turn on their desktop computers at home, as if they were starting a tractor. Some computers turn around for a while, and the sound will be quieter. Some computers have been playing a discordant symphony all the time. Why is this so, I will tell you today.

There is noise when the boot is turned on, but can the display show the signal out? If you can, it's mainly the sound from the fan, and there are fans and CPU fans behind the general power supply, and the sound from the aging of the fan will be relatively large! If the signal is not displayed, it means that the sound from the diagnostic horn on the motherboard!!

The reason for the cold in winter, it will be fine after turning on the machine for a while, and the room temperature is low.

If you are willing to do more, remove all the fans and remove the dust, clean them and re-apply the lubricating oil.

It's normal.,There's a sound when you turn it on.,It's working inside.,If it's extra-large, see if the case is not placed or the case is not installed.。

There are two possibilities, one is that the shaft of the cooling fan is deflected and produces noise, so you can change the heat dissipation fan a few times.

Another possibility is that the fan blades rub against the wires in the case, and there is no noise when you open the box and take off the wire.

It may be that the wire is stuck in the fan in the main unit, open the main case to adjust the position of the wire inside!

It should be a problem with the power supply, mine is the same as you, it was ringing before, and then the power supply broke after half a year. Hard disk possibilities are slim and slim.

Either that, the fan on the CPU has less oil.

It's definitely the sound of a fan! There's too much dust in the computer, clean it up! It's OK to add some oil to the fan...

The lubricating oil of the power supply fan is frozen, and there is no sound after running for a while.

It may be that the fan has been for a long time, and it is recommended to change it to a new one, more than ten yuan.

The noise you're talking about is not that the fan is too loud. It's a normal phenomenon ... Every time I turn on in my house, it's very noisy, and then it's fine after a while.

This is due to the automatic adjustment of the fan speed. Generally, the boot fan will turn to the maximum speed and then slow down.

If you feel that the noise is too loud, it is recommended to change to a new silent fan, or it may be that the power supply fan is ringing.

Maybe the fan of the CPU graphics card or power supply is ringing. There's also a buzzer on the motherboard, I don't know if it has anything to do with it. Take it apart and look carefully to find out what it sounds like.

That's the sound of your power just starting up.

Normal to think without.

Just go and change to a silent power supply.

The computer overheats and the fan in the case spins faster.

First determine where the noise is coming from, whether it's the CPU fan, the graphics card, the power supply, the case, or the hard drive. And then treat them separately according to the specific situation, if it is the noise of the wind fanning, then add some lubricating oil, and replace it with a new one. If it's a hard drive, find someone to fix it.

Noise when booting up may be that the fan is not running smoothly, it is recommended that you open the case, and then turn on the machine to check, it is easy to find out the reason!

It should be that the fan is out of oil, remove it and add some oil to try it!

It's normal for noise to appear after using it for a long time, this is what most machines will have, and mine is the same, it's the graphics card or.

CPU fan.

sound, you need to open the case to clean up the dust inside, with.

After the hair dryer blows and gently brushes it with a small brush, the noise will be better!

CPU fans or electric fans are short of oil and are recommended to be replaced.

This has nothing to do with disk fragmentation.

What I want to know is that there was noise before?

1. Power supply fan noise: Power supply fan noise is divided into rotation noise and vibration noise. Rotational noise is generally caused by the lack of lubrication of the fan bearing, which can be applied to the fan bearing with a few drops of light lubricating oil (e.g. sewing machine oil).

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing and clearance. If it is a dirt accumulation of individual leaves, it is enough to remove the dirt; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace the power supply fan with a new one.

2. CPU fan noise: CPU fans and fan blades are easy to cause noise, and the bearings of the fan may make a lot of noise due to too much friction due to lack of oil after long-term use. You can tear off the label on the fan hinge, add some oil and then cover.

It is not advisable to replace engine oil with vegetable oil here, because over time, vegetable oil will become viscous and affect the heat dissipation of the fan.

3. Optical drive noise: As the name suggests, optical drive noise is the noise generated by optical drive. You can use virtual optical drive software to make some commonly used optical discs into images and store them on the hard disk.

You can also use the optical drive deceleration software to slow down the optical drive, the current high-speed optical drive is completely for the market competition to speed up the crazy speed, you can use nero drivespeed to slow down.

4. Hard disk noise: Hard disk noise comes from the vibration of the hard disk. Horizontally mounted drives should be parallel to the chassis, while vertically mounted drives should be perpendicular to the underside of the chassis and should never be skewed. The most important thing is that the hard drive must be tightened and not overtightened.

5. Chassis noise: If the chassis makes noise, a styrofoam strip should be pasted in the appropriate place, and then the chassis cover should be tightly covered.

This should be the case has not been cleaned for a long time, the CPU or graphics card fan inside is dusty, just turn on the fan running at full speed, so the sound is loud, your motherboard, graphics card has turned on the intelligent fan speed control item, after running, the temperature control chip of the CPU and graphics card detects that the CPU and graphics card temperature is low, and it will notify the motherboard to reduce the fan speed, so the sound is small, if you play a large game, you need the CPU and graphics card to run at full speed, the temperature rises and the fan will automatically accelerate again, and the fan sound will be loud!

The noise generally comes from CPU fans and graphics card fans, especially when winter comes, the oil in the bearings of the cooling fan is easy to solidify together, and it will naturally improve after the temperature is high after turning it on; There is also dust, you can try to clean the dust of the fan, if the effect is not good, it is recommended to replace the fan.

Open the case, there are 3 fans, one for the CPU, one for the power supply, one for the graphics card, press and hold the other two for a few seconds, listen to the sound of the other fan, the loud one is problematic, just change the one.

It should be the sound of the fan aging, see if it's a power supply fan or a CPU fan, just change it!

It should be the sound of the fan,There are several fans in the host,The speed may be unstable and a little sound when it is just started.,After a while, the speed will be stable.。

The weather is cold, the lubricating oil in the fan freezes, and after a while, the oil melts and stops ringing.

This is a normal machine, and it will be like this when it is used for a certain period of time, and it is nothing.

It's also possible that the radiator starts up with the sound of some computers that you want to adopt.

It's your power supply fan that has dust in it, or it's your CPU fan, and you just clean them up, or you can get some oil, and if you're not professional, you'd better find a professional one, or you're breaking it yourself.

I guess it's cold, plus a little dusty, mine is the same as yours, but it'll be fine in a while, and it'll be fine in the summer.

Check that the fixing screws of each part are not loose.

It's a problem with the power strip, let a professional check it.
