I have a Q9400 currently clocked at 3.6 Ghz with 1.47-1.48 V while running. It idles at 40 or so degrees Celsius. All of this is fine and dandy, but the PC has issues with randomly locking up, sometimes it will go days just, fine others it will freeze multiple times in one day.

Any ideas? Causes? Questions?
