The computer case is very loud! There is sound in the computer case

Restart it and the sound is normal? Could this be a delusion, is the method of reboot a "hard reset"? It may be that the fan is stuck in something, and when the fan turns long enough, this thing is blown to the side by the wind, and the noise cannot be heard.

Please make sure that the sound is not coming from a fan, usually there are at least 2 fans in the computer (1 CPU and 1 power supply), you can try to stop these fans to see (of course, it is stopped within the time).

If it is related to the ghost system, then you can try to disconnect the hard disk, so that you can't enter the operating system, then you turn on the computer to see if it rings, if it is still very loud, and it is ok after restarting, then it has nothing to do with ghost, it may be a problem with the computer BIOS.

There are some software that can control the CPU fan speed, or it is possible that this software works after you enter the operating system.

Finally, if the sound is not coming from the fan, it may also be an optical drive, because if the hard drive is loud, it is useless to restart.

The case rings most likely because of a power supply problem. **90-160

Generally, the case is a fan ringing, or it may be an optical drive, you must have moved the chassis when you install the system, there is a lot of dust around the fan, which may float into the fan, you press and hold the fan with your hand when you start it, try it one by one, and see if the fan is ringing.

The problem is mainly in the hardware.

Fan, buy a good fan, which is consistent with the configuration of the motherboard;

Problems with the motherboard;

incompatibility issues;

Nothing is wrong, and so is mine.

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

If the computer has not been turned on for a long time, and too much dust has accumulated on the electric fan, this phenomenon may occur, the solution is to disassemble the computer, remove the power supply, remove the fan from above, and remove the dust. Then reinstall it, and the general noise will be eliminated after turning on the machine.

The poor performance of the optical drive is generally found on the newly purchased computer or the newly purchased CD-ROM, and there is a huge "humming" sound when reading the disk, and after eliminating the fault of the optical drive, it is likely that there is a problem with the power supply. It is necessary to take it apart and check it.

Isn't it a tick-tock-tick sound? If it's like this, it's the sound of the hard disk, and there are few hardware in the host that can start the sound, one is the fan, one is the memory, and one is the hard disk! But the sound of the fan can be heard as soon as you hear it, and the memory is generally a long and two short or a long dripping sound!

If the memory rings, it won't turn on! Your problem is the cause of the hard drive!

Check to see if there is a problem with the hard disk, if you don't run the program, the hard disk is still ringing, there is a bad sector.

Also: finding the problem.

1. When the sound appears, observe whether the small red light (hard disk working indicator) near the case switch flashes rhythmically with the sound, if so, it is the sound of the hard disk;

2. Now the CPU fans are all variable speed, which is automatically controlled by the motherboard, and if the CPU temperature is high, it will increase the speed, and when the temperature drops to a certain extent, it will maintain the original speed. Open the case, wait for the sound to appear, and judge whether the sound** is the CPU, if not, observe the power supply and the fan of the graphics card (use a small stick to stop the fan rotation when the sound appears, and see if the sound disappears);

3. For the machine you just bought, exclude the sound caused by dust friction of the fan;

Solution: Hard drive ringing is normal.

If the fan rings too loudly, it is recommended to replace it.

It is the fan and the hard disk that make the abnormal noise.

The fan is not well lubricated and loud.

Specific** problem: Disassemble the chassis and take a look at the optical drive, read the disk, and detect the floppy drive, which may be very loud.

It is best to let them deal with the after-sales service of the brand machine.

This is normal.

Because when playing games, the hard disk has a large amount of data reading and storage, so the noise is obvious at this time. Any hard drive has noise at any time, the outside world is loud during the day, and the hard drive sound is not obvious, but at night, in the dead of night, you can easily hear the noise of the hard drive.

Your computer is newly bought, and the noise at this time is normal, not caused by hard disk damage, you can rest assured.

The quality of Lenovo should be changed to trust, a big brand, and an Olympic partner, my computer is also Lenovo Jiayue, not bad.

If something goes wrong with your hard drive, your machine will run slower and hurt.

There may be something wrong with the fan.

Lenovo's hard drives have always been poor.

I hope you pay attention.

It's definitely a hard drive.
