ok well i just had repaired my windows xp a few hours before this all happened and everything seemed to work fine untill i tried re-downloading itunes. windows told me it could not install this with out xp pack 2 or something like that so i whent ahead and downloaded that, but it didnt seem to work, so i left it at that, a while later my IBM re booted and whent through the first loading screen fine untill the next screen was a black screen with nothing else on it except a small picture of a padlock in the top right corner. it allowed me to type in a password but my user account password did not work and my admin password is just blank and that didnt work either, after three attempt of a password it locks you out and u cant press any keys so you have to restart, ive tried loading the xp start up disk and running it in safe mode but none of that works it just keeps popping up on that screen. please help.
