It can be very frustrating when your PC makes strange, unwanted noises. Static noise can be caused by a variety of problems, and it can easily distract you from your work or other computer-based activities.
Why does my PC make static noise when I move the mouse?
The most common cause of a PC making static noise when the mouse is moved is electrical interference, which is a result of speakers having sub-par shielding capabilities. The interference can cause a static noise to come through the speakers when the mouse is being used.
Although electrical interference is most likely the culprit for static noise occurring when you move the mouse, there are several other potential causes too.
Thankfully, it isn’t usually too difficult to pinpoint the issue, and solve it so that you can get back to using your PC without being distracted by the static noise.
In this guide, I’ll explain why this can occur, and how you can rectify the problem.

What Causes Static Noise When Moving the Mouse on PC?
Whether you’re using speakers or headphones, hearing a static noise when moving your mouse can make it very difficult to concentrate while using your PC. To solve this problem, we first need to understand the potential reasons that it could happen.
It’s most likely that the noise is caused by electrical interference. Interference occurs when two or more devices are positioned close to one another, and their electronic signals interfere, which results in static noise if they are audio playback devices.
You may have noticed this before when you receive a message on a phone and it is positioned close to a speaker or amplifier. A strange static noise plays through the speaker, due to electrical interference.
If you’re using studio monitors with your PC, it’s very likely that the static sound is being caused by electrical interference, as they are not designed to be positioned too close to a computer. If, on the other hand, you’re using computer speakers or headphones, it is less likely to be a result of electrical interference.
- The static noise may be occurring due to a poor or faulty connection between your mouse and your PC. If you are using a wired mouse, check that the cable is in good condition. It may have worn out over time, causing a faulty signal to be transmitted to the PC.
If your mouse is wireless but has a transmitter that plugs into a USB port, check that the transmitter is in good condition. If the USB port has been broken or isn’t working properly, this may be causing the static noise every time you move the mouse.
Another potential cause for the static noise is a motherboard issue. Thankfully, there are some simple measures you can take to fix the problem, which I’ll outline in the next section.
How to Fix Speakers Buzzing When the Mouse Moves
Due to there being several potential reasons for a PC making static noise when the mouse moves, there are also many ways that you can try to solve this.
The first, and perhaps most obvious thing to try is using another mouse.
This will allow you to determine whether there is a problem with the mouse, such as a faulty cable or connector. If the problem persists when you try a different mouse, you know that the fault is coming from the computer or the speakers.
Next, you need to test whether the sound occurs through different audio output devices. If you’re currently using computer speakers, try plugging headphones into your audio output jack, and seeing whether the static noise is still there when you move your mouse. If it is, then you know it is not down to a problem with your speakers.
If you’re using studio monitors, then try playing the audio through computer speakers or headphones that are plugged directly into the audio output on the device. Studio monitors are commonly paired with an audio interface, so it’s important to rule out any problems with these devices.
- Rechargeable: Built-in rechargeable battery, no need change battery. Special soundless design for the right and left buttons, won’t disturb others.
After you’ve performed the above tests, you need to determine whether it is the USB port that your mouse is plugged into that is causing the problem. Most computers or laptops have multiple USB ports, so try plugging the mouse into a different one and see whether the noise disappears.
The next thing to do is to clean out the connector on the mouse, and the USB port. If either of these connection points gets dirty or is covered in dust, this may cause strange static noises when the mouse is used. Plugging the mouse in a few times and taking it out is a good way to scrape any dirt off the connector.
Another way to clean the connectors is by using compressed air. This will push out any dust or dirt, and then you can reconnect the mouse to see whether the problem is still occurring.
Finally, if all of the above steps fail to solve the issue, you’ll need to remove the sound card from your PC and use only the onboard audio. This will allow you to determine whether the sound card is faulty and needs replacing.

Why is my GPU making a buzzing sound?
When a GPU is covered in dirt and dust, this causes the fans to make strange noises which often sound like buzzing or static sounds. To clean the GPU, you need to connect it to the motherboard and use compressed air or a soft brush to remove any build-up of dust.
Do you need a USB port for a wireless mouse?
Although the majority of wireless mice come with a dongle receiver that plugs into the USB port of a laptop or computer, there is an alternative – the Bluetooth mouse. These devices connect directly to the computer via Bluetooth and require no USB dongle.
Why isn’t my computer recognizing my mouse?
There are several reasons that a computer may not be recognizing a mouse. Firstly, if the mouse is battery-powered, you may need to replace the batteries. Another potential reason would be that you need to update the drivers on your computer for the mouse to connect.
