My pc freezes frequently during bootup, generally between BIOS starting up and Windows XP loading up. If I can get signed onto XP it will probably work... it occasionally freezes or restarts, but once it's been running for 5 minutes, it's safe (ie. it never freezes once windows has been running for at least 5 minutes). It was working fine before, and nothing new has been installed (hardware or software). Anyone have any ideas?
