This is wierd.. I never noticed it before, so im not sure if it was always here.. but theres a faint noise that since i discovered it this afternoon, bugs the hell out of me. I have an iMac g5 2.0ghz. 20 inch.. I had the hd replaced a couple weeks ago. There seems to be a sound, like a faint whine, you know the electrical buzzing type, sounds like not static.. but hmm hard to explain.. Hopefully someone will understand me.. But when i squeeze the computer, the noise stops, and when i let go, it starts again, sometimes immediately, sometimes a couple seconds later... what could this be? Nothing seems to be wrong with my computer..
