Re: Mysterious Beep
This might sound stupid, but sometimes while playing games you might hear a beep because of sticky keys. It's this Windows thing about pressing a button for more than five seconds, and it just its way of warning you that you're holding down that key for a excessive amount of time. I'm not sure, but hey it might be the answer to your question.
