The video did not upload yet onto youtube. It will be here: http://youtu.be/tCthrmoZFM0
So I am hoping someone can help me. My custom built PC (about a year old) is suddenly buzzing on and off the more active it is (surfing, playing musing, typing alot, etc). It is silent when left on but not being used. It does not come though the speakers. I have taken the case off and it does not appear to be the fans (when I stop them for a second with my finger, it still buzzes). I have jostled all connections and nothing seems to stop it - it just eventually stops on its own and otherwise the thing works perfectly. It's just SUPER annoying. I made a video and sound clip of the buzzing and posted it here
