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 weird buzzing sound when you scroll.

Fix:
Try lowering the volume or changing audio device to see if that helps.

You could also try disconnecting your external speakers or sound system, or try using a headset 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 large files), it can produce a buzzing sound. 

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

3. 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.

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

4. 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 accompanied by other problems such as graphical glitches or system crashes, it could be a sign of a problem with the graphics card.

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You might also try updating your graphics card drivers to the latest version, as outdated drivers can occasionally cause strange behavior.

5. 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. 

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

6. Software or driver issue

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

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

7. 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 a buzzing noise on scroll.

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

Additionally, the touchpad or mouse may malfunction and need 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. 

8. 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 when scrolling 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 a specific component in your computer causes the coil to whine when scrolling, you may try underclocking that particular component and see if that reduces the amount of electrical current flowing through the coils and decreases 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.

9. Electrical Interference

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