my friends computer (gateway 838gm) will not boot into windows. he told me he was playing wow and went afk, when he came back it had rebooted. during reboot it got stuck on the windows xp screen with the scrolling bar for a good while. ive tried booting in safe mode, using best know last configuration and all that nonsense. nothing has seemed to work so far. its unclear if someone else used the computer and did something to do it, it might help if we knew, but for now i told him to shut it off for about an hour or two cuz he leaves it on 24/7. any suggestions?
