I was studying for a test a minute ago when all of the sudden my computer froze, the screen turned blue, the brightness turned all the way up, and then it changed to the desktop with all my applications closed. I didn't get any error messages or anything, and it all happened in a matter of 3 seconds or so. What on earth just happened? Edit: I had iCal, Firefox, Studycard studio lite, word, and circus ponies notebook open. All legit.
