Yes. They drive me nuts. My family had a PC that would buzz whenever you moved the mouse. We have a bunch of cheap LED lamps in my apartment and every one has an especially loud transformer.
My main laptop is making similar noises all the time, I think they come from the CPU.
The CPU itself doesn't produce sound, but inductors (coils) can. Therefore, when you move the mouse, the CPU power increases, potentially causing inductors to go into resonance.
Graphics system usually. Back in the day I used to be able to tell where on the screen the cursor was from the pitch of the coil whine.
I buy better hardware nowadays ๐
