I originally built my computer in August and since I have had multiple instances of my computer losing display. I am not sure what is causing this. Any help troubleshooting this would be very appreciated. When it stops displaying it also required a hard reboot.
p9x79 pro (3102 BIOS Version)
Corsair HX Professional 850 Watt
XFX 7950 Factory Overclocked
This happens when I try to run windows experience index, and multiple games such as Crysis and Arma 2 Operation Arrowhead etc. The weird thing is some games run fine like bf3 and shogun 2.
