No POST after Vista install??

Hello,

I recently decided to install Vista 32 bit on a machine that had been successfully running XP Pro on it for months. This was not an upgrade, it was a clean install. After the Vista install completed and the machine restarted it was black screen from then on out. The machine no longer boots or completes the POST process - just a black screen. I am unable to access the BIOS either. Is it possible that my motherboard and/or processor is fried?

Machine specs:
Intel D875PBZ motherboard
P4 3.2GHz processor - socket 478
4GB memory - Buffalo PC3200DDR Dual Channel - 2 matched sets
Cooler master 500w PSU
NVIDIA 6800GT video card
Primary IDE C: drive standalone
Secondary IDE D: DVD drive standalone

What I've tried:
Remove power cable and CMOS battery over night
Reseat the processor
Reseat the memory - tried to boot with 1 stick, 2 sticks etc
Reseat video card
Reseat IDE cables
Remove and reinstall entire motherboard and all connections
Replace PSU with 750w Corsair
Tried all drives+cables, video card and PSU in other machines and they work fine
Tried working video card

All drives power up, all fans power up but no POST, just black screen. This machine worked PERFECTLY with XP on it, for months. Anything else I can try? The only thing I do not have access to is another P4-based motherboard to try the processor in. Please tell me I don't have to trash this board?!?!

Thanks in advance.
