Movement of the mouse triggering coil noise?
Movement of the mouse triggering coil noise?
Check if they’re powered off or disconnected. If fully unplugged, try connecting the mouse to another machine and observe if it still makes noise. If it does, the issue lies with the mouse itself. If not, another part of your computer might be causing the sound when you move the mouse.
I’m sure you experience some unusual power issues because your PSU makes noise when lights are switched on. As for the GPU, it might be struggling under those conditions.
The inductor coils move when subjected to stress. When the GPU processes tasks like rendering graphics or responding to input, rapid changes in the display or mouse movements can trigger noise. It’s unlikely your GPU is the issue unless the problem occurs without any app activity.
This discussion is quite outdated, but I ran into the same issue on my roommate's computer recently. While doing some folding@home, I noticed a coil whine when moving the mouse across the desk and thought my roommate's GPU might be struggling during the task. The GPU was running at full capacity, but the whine only appeared when the mouse hovered over interactive elements on windows or elsewhere. I tested inside the PC to pinpoint the source. It turned out the problem was with the power supply unit (PSU), which is around four years old. A replacement PSU or better power filtering might be needed. It's a minor annoyance, but it won't cause immediate system failure. Wishing you all good luck with your troubleshooting!
