Hi My pc keaps rebooting during normal use. When i'm playing games or when i'm encoding video. Sometimes it hangs when I boot up, the mouse freezes and I have to manually reboot. I've reinstalled xp etc a few times but the problem is still there. I disabled my SATA HD and booted up with a normal 40 gig IDE drive with no problems seen as yet. Can a SATA HD cause this type of problem? Any feedback will be appreciated.
