ARRRGGH!

So I went to turn on my laptop tonight and it will not work! Apparently sometime between it shutting down perfectly last night and my pushing the power button tonight, it found the time to corrupt some file. Greeeeaaat. It sounds like I have to reformat the entire computer. ALL my schoolwork is on there, my wedding planning stuff, EVERYTHIGN. At least I backed up all my digital photos this past week... *Sigh*
