I bought an asus P7P55D-E LX mob, 2x2gb corsir DD3 ram (XMS3), be quiet staight power 680 psu, intel quad core i5-750 cpu and GTX 285 Graphics card. Built it, and green standby light lights up on mob but absolutely no other sign of life from any of the other components. Reseated everything, checked wires, tested psu with another pc and that is working fine. Appreciate any help, advice, info. Thank-you
