odd... well, one thing you have to learn is BACK UP!!!!!!! I back up my files to a cd twice a month, put it in a case, and stow it away in my desk drawer. Also, I ghost it to a hard drive that i also keep in that drawer.
you should also start using go-back, or a file similar. It allows you to go back to a certain date that the computer was on and resets all files that were on there, or replace files that were lost.
