Why Computer Makes Buzzing Noise When Scrolling

In this article, we will explore some of the possible reasons why a computer makes buzzing noise when scrolling and what you can do to fix the problem.

Computers are an essential part of our daily lives, but they are not always flawless. A common problem that many computer users encounter is a buzzing noise coming from their computer when they scroll. 

This can be annoying and even alarming, especially if it is not clear what exactly is causing the buzzing noise or whether there is something wrong with the computer. 

There are different kinds of computer buzzing noises as well as a range of causes from software to hardware issues. Normally, the buzzing may be something benign and easy to fix, but there’s also the possibility of it being a sign of something more serious going on with your system.

Identifying the source of your computer’s buzzing noise will help you find a fix for it.


If you are incredibly concerned about the buzzing noise from your computer, it is always a good idea to have a professional take a look at it to diagnose the problem and recommend a solution.

Possible Reasons your Computer Makes Buzzing Noise When Scrolling

Here are a few probable causes for the buzzing noise on your computer when you scroll:

1. Excessively loudspeakers

The noise could be coming from your computer speakers. If the audio volume on your computer is turned up too high, the speakers can produce a buzzing sound when you scroll. Try lowering the volume to see if that helps.


Try disconnecting your external speakers or sound system and see if the noise goes away.

2. Hard disk working too hard

The noise could be coming from the hard drive. If the hard drive is working hard (for example, if you have a lot of programs running or if you are transferring a large file), it can produce a buzzing sound. 

This is usually nothing to worry about, but if the noise is particularly loud or persistent, it could be a sign that the hard drive is failing.

4. Malfunctioning power supply

The buzzing noise could be coming from the power supply. If your computer’s power supply is not functioning properly, it can produce a buzzing sound. This could be a sign that the power supply is failing and will need to be replaced.


To solve this problem, try replacing your computer’s power supply system with a higher-quality one.

5. Graphics card issues

The noise could be coming from your computer’s graphics card. Some graphics cards are known to produce a buzzing sound when they are under load. 

This is usually not a cause for concern, but if the noise is very loud or if it is accompanied by other problems such as graphical glitches or system crashes, it could be a sign of a problem with the graphics card.


Try resetting your computer to defaults to see if this problem will be fixed. But you may need to replace your graphics card if it is faulty.

6. Inadequate cooling

A faulty computer cooling fan, which could be brought on by dust or other debris obstructing the fan blades, is another potential cause of the buzzing sound. 


Try cleaning your computer fan and see if this will help solve the buzzing problem.

7. Software or driver issue

Your computer’s buzzing noise could be caused by a software issue, such as a driver conflict or malfunctioning software.


To fix this problem; check for and install any available updates for your operating system and drivers.

8. Dirty or damaged touchpad or mouse

Your computer’s buzzing while scrolling may also possibly be because your touchpad or mouse is dirty or damaged. 

The dirt or damage may cause the cursor to jump or falter, which may create a buzzing sound. 


To troubleshoot this; try cleaning your touchpad or mouse and see if the buzzing will dissipate.

Additionally, the touchpad or mouse may malfunction and needs to be replaced. If you’re using a laptop, the touchpad may be combined with the keyboard, which could mean that the keyboard itself needs to be replaced. 

9. Coil whine

If the buzzing you’re hearing from your computer is high-pitched, it could be what’s known as coil whine. 

A coil whine isn’t necessarily a problem, it is simply an electronic phenomenon when components vibrate at the exact frequency to produce the high-pitched whine. This noise may be more pronounced when the device is running at high speeds or when the processor is under heavy load.

Unfortunately, in most cases, there isn’t much you can do to fix a coil whine since it’s not exactly a problem. You may just have to learn to live with it. 

However, if the noise is too loud or disrupts your experience, you can contact the manufacturer of your device to see if they have any solutions.

In some cases, if the coil whine is caused by a specific component in your computer, you may try underclocking that particular component that is causing the noise and see if that reduces the amount of electrical current flowing through the coils and decrease the noise level.

Alternatively, changing the location of your device or the surface it is sitting on may sometimes reduce the noise level or make it more bearable.


In closing, there are several possible reasons why your computer may make a buzzing noise when scrolling. It could be a problem with the speakers, the hard drive, the power supply, or the graphics card. If you are experiencing this issue, it is important to try to identify the cause of the problem so that you can take the appropriate steps to fix it. 

In some cases, the problem might be as simple as adjusting the audio volume or closing some programs to reduce the load on the hard drive. 

In other cases, it might be necessary to replace a malfunctioning component or seek professional help to diagnose and fix the problem. 

Whatever the reason, it’s a good idea to be aware of any odd sounds or behaviors coming from your computer because they could be an indication of a problem that needs to be fixed.

If the problem persists after troubleshooting and taking action with the above suggestions, it may be best to seek technical support from the manufacturer of your computer for further assistance.
