Why is my computer loud when it turns on

Generally, it is the fan of the main unit.

After a long time, the noise caused by the lack of oil in the fan, the faster the fan speed, the louder the noise, the solution is the solution. Fill the fan rotor with oil. Not too much. Generally, the ball bearing with a good fan has very little noise. It's no problem to fill oil regularly!

When the computer is first turned on, the fan will rotate at high speed for a while, and if the fan is out of oil, it will be very loud, and the sound will be much quieter after entering the system. After excluding the vibration caused by the fan and the sound caused by the object touching the fan blade, the most likely is caused by the lack of oil, the refueling method is very simple, first remove the fan from the seat (nonsense), and then see if the back of the fan (a few in the front) is sticky with a round plastic sheet, generally self-adhesive, remove it, you will see the motor bearing of the fan, when the oil here is too dry, the fan will ring, then find some sewing oil or car oil, not too sticky, The idea is to drop a drop or two of oil into the bearing cavity, see that the oil is soaked in the bearing (the fan must be kept level), be careful not to let the oil spread to the surface of the fan, otherwise it will affect the adhesion of the plastic sheet, at this time, apply some glue around the oil hole to stick the plastic sheet back and air dry for a while, and install the fan back after drying, and then turn on the machine, is the sound much smaller?

There are generally three fans in the case: CPU, graphics card and power supply, the first two are easier to get, and the power supply fan is more troublesome because it is necessary to disassemble the power supply. You can listen to which fan is making the sound before doing it, or simply deal with it all together, so as not to toss again and again in the future.

The lubricating oil of the CUP fan bearing solidifies when the weather is cold, so that the fan sound is louder when it is just started.

It is also possible that your hard drive is not tightened, remember that the case cover is not tightened, go to the computer store to clean the dust, or clean it yourself, then by the way, wipe the CPU and the fan on the graphics card. It's definitely dirty.

That way, the machine won't be so loud, hehe.

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.
