Solve : strange sound coming from computer??

1.	Solve : strange sound coming from computer??
Answer» Sometimes when I use my computer, a strange KIND of whirring sound STARTS to happen. It will go away if I move my computer but IM not really sure why its happening or what it is. I've noticed a performance loss since this has happened. Anyone know what it is and how i can fix it?I would suggest opening the cover and trying to ISOLATE where the sound is coming from. Someone in the past reported a similar problem, but I think he said his computer "glowed" also.
