When i install windows XP service pack 3 onto my windows xp media center edition 2005 it installs fine and then asks to reboot but when i do it gets to the windows loading page and then goes blue screen every time so i had to run safe mode and then system restore to roll back to service pack 2 to fix the problem. Does anyone know why it would do this. Could it be because i have corrupt files in the system files. i downloaded the service pack from Microsoft's website and the windows update but nothing. I have a AMD antholon motherboard if that helps at all. if anyone knows anything on how to fix this error please let me know.
