Ok. I've plugged in the H.D.D L.E.D to the motherboard and etc.. in the correct places and it brings some extra stuff but didnt bother to connect it anywhere because I didnt know where to and didn't wanna mess anything up. I have a ECS Motherboard and I wanted to know if that was the problem...i have a pretty old motherboard socket 423 (sucks). Can anyone please help me or at least try?????
