Hi.
I just bought so new hardware for my pc - Mobo is an ASrock B85M, and CPU is a i5-4570.
my previous build:
CPU: intel q9450
Mobo: Asus G43 *****
RAm: corsair XMS3 4gb
Graphics card: ATI HD 5870 1GB
PSU: Huntkey 550W Green power

My previous build worked perfectly, when I installed the new mobo and cpu, it still worked perfect. I installed my mobo drivers. When I inserted my gfx card, the PC did not want to start up. The fans go on but nothing els happens. When I remove the gfx card everything works again. I tried to change some settings in the bios, but nothing helps. IS the mobo damaged? or is my psu to small? I tried the system with a gtx 460 and it does the same. When I insert an old gfx card that doesnt need extra power cables it works. But as soon as i insert a gfx card that need the 6 pin power cables nothing happens.

Ok I had it at the PC shop. The GFX card isnt working for some reason. Not even in my old build anymore. But now the pc restarts the whole time when I start it up, that is without a gfx card inside. When I remove one RAM module it starts up. Ive got two Corsair XMS3 4GB 1333MHz modules in the machine. But the system only boots successfully when only one stick is in the pc, regardless of which one it is. Is this a compatibility issue?
Accourding to this link my RAM isnt on the list of compatibility:
http://www.asrock.com/mb/AMD/970%20Pro3/?cat=Memory
AND accourding to this site my mobo isnt on the compatibility list of the RAM:

My question is how can the RAM not be compatible, but the pc starts with one module of RAM, but not with two
