power supply? under load graphics card require more watts. makes me wonder if you have enough power reaching them/entire system

Jason is write. Check you PSU make sure its good one, meaning a good brand
you should have at least 620 watts.
also check your temps. might be shutting down due to heat.

Grab a copy of HWMonitor and check your CPU and GPU temps.

the PC rebooting or shutting down is a sign of afailing psu. Funny - you mentioned everything in your system config EXCEPT the PSU. i hope it was a typo and how many HDD's are your running as well as the total capacity?
