Thanks for your responses, I know the power supply is good, if use another power supply it does the same thing, faint clicking sound and the little green led on the back of the power supply flickers with the power supply. I guess what i'm asking is has anybody out there had this issue before? I have unhooked everything from the board except for the cpu and when i plug the cord into the power supply I get the clicking sound. No lights, led's or anything just the clicking.
