I am seriously struggling with this hair pulling problem with a pc i built for a friend. Its Specs are:
HAF X Case
Gigabyte GA-890FXA-UD5 REV 3.1
Crossfire XFX HD 6970
8GB G Skill Ripjaws 1600 MHz
Heres the issue; every time i click on an icon to start a game like Crysis or Halo 1, the system instantly freezes and I must flip the switch on the PSU to turn it off. I ran mem test for 2 hrs and it passed 100%. The voltages on the PSU are near perfect. I have tested all kinds on single and dual gpu setups in all the pcie slots. I have tried using a spare GTS250 gpu. I have tried older GPU drivers. I ran a couple of tests with intel burn. Nothing is overclocked and i have loaded the mobo's failsafe defaults. This narrows it down to the motherboard and the osand its drivers . I am not sure what else i can do except start rma'ing things. Any input on this issue would be greatly apprecited.
