This is progress though - at least I have power on the board which will allow me to use a post diag card to see how far along the mb is getting through startup before failure. Anyone have a pci post diag card they'd be interested in renting out for a night? Unfortunately this board is built with no startup beeps.

You will also get this kind of behavior if cabling or components are not connected correctly. I am assuming you are doing your initial testing without disks from your original descriptions, as a reversed floppy cable can cause that kind of behavior. The other thing to check is that you have the memories in the correct slots. The MB manual from Tyan said you needed to start with slot pair 4 which are the ones closest to the power connector. Is it possible that the heat sink installation is shorting out to something? >From the pictures it doesn't look likely, but you never know. Are you sure that the CPU fan is OK? Try powering up without the CPU fan connected to the MB. If everything starts to spin, then shut it down again or make sure you have another fan blowing across the heat sink until you can get it shutdown. And last since I've done this myself, so I always have to check, are you sure that the jumper on JP25 (Clear BIOS) are on pins 1-2 and not 2-3?markh

Motherboard isn't damaged - I sent it back to tyan and they say it works fine for them. The processors are the only thing that I've not ruled out. I can't image that I'd get 2 bad processors together though....I've tried them both seperately. It'd be nice to find someone with a board that takes these new nocona chips so I could test mine out.

By "spins once" you mean the fans make about one turn and then stop?
Sounds like a bad power supply to me. I hope it hasn't damaged your mobo.
FreeGeek sells power supplies cheap. If you're friendly, the folks in
the thrift store might let you bring in your machine, test your power
supply there and try one of theirs.
