i have the same problem, but i know that the ram is not on the list for supported ram, but i figured it would still at least post, the ram, gpu, and psu work in another pc, cant test my 8120, but i did put an am3 cpu in it and the problem persists. what are the chances that it is just the ram?
You might need a BIOS update for your FX CPU. Some boards need a BIOS update for them. If that doesn't help or even let you do it, then your board could be dead. Check for bent pins like OP had.
