Brand new mobo. Upgraded to latest BIOS, disabled Quiet option, reseated Memory, CPU and fan. Tried two different video cards, tried two different memory sticks (1066 and 1600 ). No post no video. Fans spin, mobo light is on but memory light does not. Tried a new and an used FX8320, same result. TRIED SEMPRON CPU AND MACHINE BOOTS UP WITH ANY CONFIGURATION, does not matter video card or memory stick, it boots just fine. I ran out of ideas, please help
