psu problem? can you try a new power supply?
driver problem? have you tried a different video card driver? <--this will usually not cause a restart.

Define "auto shutdown". Does the screen go black and the machine reboots or does the game exit and Windows reboots normally?

Could be the mobo shutting down from the bios for temperatures (temp threshold). Many bios/s have a setting for temperature shutdown (CPU).
