Hello marktreg, thankyou for helping us. I hope you can tell us how fix it. My laptop was fine before it happened. I did not notice anything funny happening before. I just turned it on when I got home and it would not start up. My brother said it might be a virus that caused it. He told me he typed chkdsk /r into the console. It took about half an hour to do and it said no errors were found at the end. My xp disk says microsoft windows XP home edition with service pack 3 on it and my laptop has windows xp on it. I dont think I have ever defragmented my hard drive. Is that ok?
