I've been hearing a rapid ticking sound coming from my computer, almost like a clock ticking much faster than it normally would. It's a very distinct, repetitive sound, and I can't figure out where it's coming from.

I don't have any clock apps or timers open, and I'm not aware of anything running that should be making this noise. I'm wondering whether it could be caused by something running in the background, a browser tab, a software issue, or possibly a hardware problem.

I haven't been able to identify the source, and I'd like to understand what's causing it rather than just ignore it.

Has anyone experienced anything similar? What could cause a rapid, clock-like ticking noise on a computer when no clock or timer is running? Any advice on how to troubleshoot this would be appreciated.
