OK, I was surfing the internet, and all of a sudden the computer freezes. Immediately after it freezes, a drilling sound was coming out of my speakers. I couldn't do anything, like crtl+alt+del....so I just pressed the reset button on the case. This is the first time it has happened, so I'm wondering...is it just your normal freezing of a computer, or something else? At the time of the freeze I only had firefox, winamp, torrent, folding, and everest opened.
