Agh! New mini-system doesn't get video output!

[hokatichenci]

So I just built a new mini system of the one in my sig, specs are as follows:
Antec P180
a8n32sli
Seasonic S12 600w
evga 7900gt
corsair xms 3200-2048c2 (2x1gb sticks)
amd64 4000+ (single core)

Basically, I turn on the system, the fans start turning, but nothing comes up on the screen. I tried 2 different monitors and neither get output. The only way to turn off the machine is to plug the power or to hold the power button in for a few seconds. Any ideas?

Things I've tried:
Reseating/removing the RAM
Using the other video pci-e slot
Multiple monitors (vga only, not dvi)
If theres any vocal POST, it doesn't work
Theres no speaker hooked up to the +5/ground/ground/speaker line

Try clearing your CMOS and see what happens.

Thanks for the advice, the problem turned out to be a lack of the 4 pin connector. The EZPLUG didn't work for some reason. The systems running happily without having to reformat even
