When I don't have my power cable plugged in and I'm watching a video or playing a game, sometimes the picture will completely freeze, no mouse movement, and sometimes the sound will be stuck on a millisecond of loop. It then goes to a blue screen saying something about, "if this is the first time this has happened, restart your computer etc." and then if it has happened before to update drivers etc. (which I did). I noticed it only happens when I'm using something with video or games (not flash games). Any ideas?
