Dave it pretty obvious that its nothing malicious. If you are just freaked out about something happening to your computer I wouldn't worry.
Was it a software or hardware crash? Just out of couriosity what did you pay? I redo 3-4 computers a month for nothing(usually end up getting a case of beer, a bottle of something or $50+ donation). You should make a computer geek friend the stores soak you every time. I'm actually logged in from one right now that I'm just finishing up(windows update is slow).
