I'm not what to do or even where to look. It just quits for no appearant
reason. Sometimes it stays on for days at a time with no problems what so
ever. It seems as if the problem occurrs mostly when I am watching video
streams or using media explorer to listen to mp3s. I can't seem to run spybot
or even my virus software either wihout it quitting.

I'll define quit. No error messages, nothing. It just shuts off.
