It's a windows halt error (blue screen), and vista and xp are set to not display them by default. I'm hoping everyone knew that, but if you didn't you might want to Windows Key + R, eventvwr next time one happens. Nice when programmers put in error codes to diagnose issues right?
Also, you can disable automatic restart by going to system properties (Windows Key + pause/break) -> advanced -> startup and recovery, and uncheck "automatically restart."
