If you've swapped out everything except the motherboard, then it's the
motherboard. I can only think of two things would might want to try. The
first would be an upgrade to the BIOS on the motherboard - try putting
something more up to date on there. There other would be to have a look
at the BIOS options and see whether there's anything funny? Stuff like
clocking on rising / falling edges, crazy nonsense like that. Checking
DMA is enabled. Anything related to memory access and interrupt
handling. 

I think it would be worth trying the PCI card in there, though. 

Cheers,

Alex.
