Problems that i am having in XP is very annoying because i have formatted the hard drive to NTFS and it is my new PC. The problems i am having is that my pc rebooot at random times, even while i am installing some programs, or playing some games, My PC runs at full speed and at other times its running slow. The "Automatically Reboot" feature is unchecked in the advanced options. Can anyone help me try to solve the problems?
