Thanks for your reply. I bought the computer from Dell's website and received it around the end of July. I guess I can contact them and see what they say. If the data can't be recovered it's not a big deal since I saved most of my stuff to my flash drive.
I was having problems with my laptop that day (September 11, ironically) and just wanted everyone to know that I took it to work with me the next day and later that afternoon it mysteriously started working again and has been fine ever since. Now if I leave the room for awhile I make sure I just shut it down, I don't let it go into sleep mode because then I seem to have problems.
