My computer is very loud when it starts, and it is not very loud when I enter the system, what is go

It's very loud when it starts up, but it's not very loud when it enters the system", and "the kind of sound like gears" should be a fan problem. Solution (1) Brush the ash and oil; (2) Replace it with a new one. If you are not afraid of trouble, the former is both economical and practical.

You can use a small brush or a large oil brush to blow while brushing (it is best to have a "leather tiger" for blowing soot, or you can use a hair dryer to hit the cold air gear, or even use a pump to install a "gas needle" for playing basketball); To apply oil, uncover the circular covering film in the middle of the fan, let the shaft be exposed, drip a little high-grade lubricating oil (do not use cooking oil, because the cooking oil will be sticky for a long time, affecting the operation of the fan), and then cover the film. Sometimes not all of them are ringing, how can you tell which fan is ringing? You can take a chopstick, turn on the case to turn on the power, put one end of the chopsticks on the board with a fan, and the other end on the face, feel a significant vibration, and the vibration disappears with the "roar".

After brushing and oiling, the problem could not be solved, so it had to be replaced with a new one.

Maybe this is the computer's detection of the optical drive when it is turned on. If so, you can press the DEL key to enter the BIOS settings when the computer is turned on.

It's unlikely, though.

It is also very likely that there is something wrong with your power supply, change to a good power supply to test it. You can also take a look at this:

Do you live in the north The weather is cold and the fan is frozen.

Something must have come loose!

Is it loud?

If you don't get it, it's normal, it's nothing

The hard disk will be detected when it is turned on.

Light zone pull or something.

It's normal to be a little loud.

The computer keeps ringing when it turns on:

1. If there is too much ash in the computer fan, clean the ash, or replace the fan.

2. There are many background programs on computer boot, and the hard disk has been running at high speed, so use cleaning software to clean up useless background programs and clean up boot startup items.

Hello, the computer sound is generally the sound of the exhaust fan, it may be that your computer is old and produces more heat, the exhaust fan has been in a high-load working state, or it may be that there is a problem with the exhaust fan of your computer, I hope to help you

That should be too much dust in the fan.

My computer is the same, I have disassembled and dusted it several times, and now the small fan is not working, you can change the fan.

It is recommended that you turn on the host and check the CPU fan and graphics card fan, as well as the power supply fan, the most likely is the CPU fan and graphics card fan, which is a frequent problem.

It is the case alarm tone, and the long ring is a memory problem. Check the memory to see if there's too much dust to try a different memory. I've encountered it before, it's just that there's too much dust.

This solution is applicable to XP Vista Win7 system.

Problem Description]:

Computer noise, fan noise.

Cause Analysis]:

1.The optical drive has an optical disc caused.

2.Hardware failure.

Solution:]:

Solution 1: Check the optical drive.

1.If there is a disc in the optical drive, please take out the optical disc when the optical drive is not in use, otherwise every time you boot up and start up, you will check the peripherals of the optical drive and read the optical disc, 2The vibration and sound of the computer will be relatively loud.

Solution 2: Detect the hardware and fans.

1.The hard disk disk will squeak or click when reading data on the track, as long as the computer is running more frequently than the case of frequent crashes, the hard disk sound is normal, especially the old machine hard disk aging or the sound of the large storage hard disk is louder.

2.If it is the sound of a fan whining, the computer has a temperature control setting, and with the length of computer use and the temperature of the computer, the speed of the host fan, especially the CPU and graphics card fan of the notebook, will change.

In the same way, if it is an old machine, it is recommended to clean the dust of the graphics card fan, CPU fan, and host power supply fan, and if the effect is not obvious, you can appropriately add the special lubricant for the fan or replace it with a new one.

It is recommended that you go to a professional repair shop to clean up the dust from the graphics card fan, CPU fan, and host power supply fan to avoid unnecessary hardware damage.

It has nothing to do with memory, there is a sound to check the fan and the hard disk, generally there is a problem between the two, focus on checking the fan, it may be that the line in the case has touched the fan page!

You check the fan inside your case. You open the lid on one side of the case, remember not to turn on the machine first, turn on the machine you are on, and then use an insulating object to gently move your fan a few times to react, then you have to change the fan, you can repair it yourself to see if you can fix it, if it doesn't respond, it's a problem with the hard disk.

It may have something to do with the power supply, I used to turn on the computer always ringing, but I checked the fan, and it was not the sound of the fan, and then I learned that the fan of the power supply was ringing, and then my power supply was broken. If it's not a fan, it's probably the power supply.
