Why is my computer buzzing and all the time

This should be a fan problem.

Same as my desktop, you wipe the dust off the inside and the problem is solved.

Computer sound problems:

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.

There can be a variety of reasons why your computer is buzzing, and here are some of the possible ones:

1.Fan noise: Fans inside your computer may hum due to dust or mechanical failures.

2.Hard drive failure: The hard drive may hum when reading and writing, and if the sound becomes unusually loud or frequent, the hard drive may be faulty.

3.Power failure: The components inside the power supply may hum due to aging or malfunction.

4.Faulty graphics card: Fans or components inside the graphics card may be humming due to malfunction.

5.Other hardware failures: Other hardware components such as motherboards, memory modules, etc., may also buzz due to faults.

If the computer is buzzing, it is recommended to check the hardware components inside the computer in time to determine the cause of the failure and fix it in time.

Summary. Hello, I have found the most common situation for you: the CPU fan is too dusty, and the fan bearing is aging and the host is loud when the computer is running.

At present, most CPU coolers are equipped with fans to achieve the purpose of rapid heat dissipation. If the computer is used for a long time, a lot of dust will accumulate on the CPU cooling fan, which will hinder the normal rotation of the fan and produce noise. This is because the bearing of the CPU fan is aging or lack of oil and dry, and there is a gap between the bearings, which causes the sound of colliding back and forth when rotating, which can drop a few drops of sewing oil into the fan bearing, such as.

The power supply fan is dusty or the computer is loud due to aging. The power supply is also equipped with a fan to dissipate heat, so it will accumulate dust or deteriorate over time. Since the power supply fans are all encapsulated inside the power supply, it is more troublesome to clean up the dust of the power supply fan.

It is best to repair it with a computer, I hope it can help you.

I can't turn it off now.

If you can't turn it off, you can only force it to shut down. Such as removing the power cord.

Will it keep ringing?

Yes. You need to turn off the machine first, and then you can disassemble the main unit to clean the dust first. If it still doesn't work, you need to go to the after-sales service for maintenance.
