Bought a Asus M4A785-M and AMD Phenom II X4 965 BE combo off Newegg last week. Long, long story short: It immediately shuts the entire system when doing the DirectX 10 ALU assessment test. It completes the test when I underclock the cpu to 2ghz and lower. I am planning to RMA the entire combo tomorrow but am afraid the exact same problem will happen again with the next combo. Other components are Nvidia EVGA 8800GTS 512mb, 1x2GB stick of samsung ddr2 667. The shutdown also occurs in heavy action in COD6. Any help would be appreciated. one last note, all the cpu and memory settings are set to AUTO in the bios, except for the multiplier when I underclocked.
