Why Computer Makes Buzzing Noise When Scrolling

Scrolling on your computer should be a seamless and quiet experience. However, some users have experienced a perplexing problem where their computer makes buzzing noise when scrolling.

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. 

If you’ve noticed an unexpected buzzing noise accompanying your scrolling movements, it could either be resulting from a faulty or overworked hard drive, a malfunctioning power supply, a damaged touchpad or mouse or even something as simple as too-loud speakers, a coil whine when scrolling, software/driver issue, electrical interference, or inadequate cooling.

In this article, we will explore the common reasons why your computer makes noise when scrolling and provide some troubleshooting steps to help you resolve the issue.

Note that there are different kinds of computer buzzing noises and a range of causes from software to hardware issues.

Normally, the buzzing may be 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.

Understanding the possible causes of this buzzing noise can help you diagnose the problem and find a solution.

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

To answer the question ‘Why does my pc make a buzzing noise when I scroll?’, here are a few probable causes and fixes.

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.

You could also 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 malfunctioning, 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 deafening 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.

You might also try updating your graphics card drivers to the latest version, as outdated drivers can occasionally cause strange behavior.

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, hence the computer making buzzing noise on scroll.

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 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 a specific component in your computer causes the coil to whine when scrolling, 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.

10. Electrical Interference

In some cases, electrical interference from other devices or components can cause buzzing noise when scrolling the mouse.

This interference can occur if there are any loose wires, improper grounding, or if the computer is placed near other electronic devices that create electromagnetic interference.
