Funny ironduke, yer getting soft I guess
Sorry about your prob bagwafu, sounds like a monster!
With a new mobo and new HDDs, I assume you used the SATA cables that came WITH the mobo?
If you are getting BSODs (apart from the BIOS not detecting things right), then I would venture to blame RAM or CPU before power supply. Generall a voltage problem wouldn't result in various BSODs, but I may be wrong there.
Download memtest86 and burn the ISO to CD, boot from that and let it run at least an hour. Or at least until it test ALL your RAM multiple times over.
Then, I'm drawing a blank on a good CPU tester, I use a Windows based one called CPU Stability Test. I think this is it:

The other CPU test I use it Micro2000, but that is not free.
Then, of course, you want to use Seatools from Seagate to check the drives out.
If all else fails, it may be time to take it to a shop, though more money it may be. But I must say I'm surprised you're still having trouble after a new mobo and HDDs, shocking.
good luck
