I just got a new motherboard, processor, 2 sticks of ddr3 ram, and a new video card. Same 2 hard drives on it, one with Windows 7 64 bit on it, the other has xp installed but I haven't used it in years, and 2 old sticks of ddr3 ram. I plug it all up, set my computer up to go and I get this error. New equipment specs are:

Motherboard: ASUS Crosshair V Formula 

Processor: AMD FX 8150, 3.6 GHz, 16.0 mb total cache 

Ram: Corsair-Vengeance 4gb ddr3 

Video card: EVGA - GeForce GTX 550 TI 2GB GDDR5 PCI express 2.0 graphics card

It worked just fine with all my old stuff in it, I'm just upgrading for a game. All serious advice and help is appreciated.
