I just bought a dell Inspiron 9800 that was built in 2004, for 40 bucks. I tried to use it and when I got to the user screen to select a user that that was the owners , it worked then it automatically signed me out, I have no idea on what to do with out going to someone and pay for them to do it , I would like to know what I can do to fix it, I wanted to do a system restore, let me know my options I kept pressing f8 and it gave me options just want to play it safe on what to do
