Um, I was wondering if someone could help me figure out what my computer's doing... Sometimes when I'm using the computer, I suddenly hear a continuous, high pitch noise coming from my computer. I don't know what part of it it's coming from (could be power supply or fan...I dunno). All I know is that it goes away on its own after so long, or goes away when I shut the system down, and that it drives me insane in the meantime.
Anybody know what it could be? I get uneasy leaving the computer on too long because of it.
