I bought a brand spanking new gigabyte a75m ud2h motherboard as well as a processor for the FM1 slot (came as a bundle). I hooked it all up but for some reason i'm not getting ANY reaction when i turn the computer on, no fans no light on the motherboard nothing. When i plug the power back into my old motherboard it starts up just fine. So the power switch is fine, the power source (650W) is fine...not sure why my machine is not starting up with the brand spanking new mobo & processor =( Any suggestions? I have tried putting the power button pin in every slot on the F-board, cannot get any reaction from my tower.
