Another Setback

I put the essential bits into the case; Motherboard, processor with the stock AMD cooler, the two sticks of RAM, and a Hard disk on SATA1, and a case fan plugged into the motherboard. Then I stuck the power cords into the motherboard, connected the power switch to the (very tiny) pins on the front panel header. The power led was on and I was feeling quite hopeful, but clicking the power switch...
nothing

No fans. No beep code. Not even a "phhhhut" and smoke.

Ho hum. Looks like the power supply or the motherboard will need to be RMA'd.
