Shuttle AV49VN apparently dead

[freebus52]

I had purchased a new AV49VN MB, with a P4 2.8G, 512MB ram, Chaintech FX5700 video card and Powmax LP6100D 400 w power supply. Only the fans work (CPU, videocard, PS). No beeping, no video, no drive access. Four second power down timer on power switch works. It seems like I have built a very expensive four second timer. MB and CPU have been replaced but exactly the same symptoms. I have even tried another used power supply. Next step is to try a NEW 450 watt supply. Yes, the P4 4 pin ATX connector was connected. I have built many systems without issue. Time to give up DIY?

Have you tried posting out of the case, with just the video card, one stick of memory, cpu/heatsink. I've never had a new board doa, but maybe I'm just lucky. Be sure your power switch is connected correctly. I would also try a different video card.

I will try this out of the case.
Thanks

It turns out this may be an issue of the motherboard not accepting "Prescott" CPU's, as opposed to Northwoods CPU's. I can not find this on their website, however their tech support contacted me with the info.
