I have Windows XP home service pack 3, pent. 4 3.2gb 1024meg ram. When i start pc windows loads to user accounts page i choose the user (heres where the fun starts) i hit any key in the password field and it locks up. I tried safe mode to the same result. I then decided to try to boot with XP disc it said please choose correct drive and reboot. I went into F2 boot section and changed the boot priority and saved got the same result. went to F11 did the same. Same result. Thought i would mention i tried 3 more cd/dvd drives to rule out a bad drive. everytime i changed drive the bios saw the change.
