Gigabyte ex58-ud4p
Xeon 5670 (My i7 920 works flawlessly)
Bios 14p

I can boot into windows 10. I can overclock the xeon. I can game on it.

However everytime I restart Windows it hangs at a black screen and won't post

Powering on from cold is never an issue

Am I missing something in the bios pertaining to the SSD ?

Ive done the standard clear cmos etc.

I can take out xeon and put old trusty i7 920 and it works perfectly
 
Solution
At least according to the manufacturer's website that CPU isn't supported by that motherboard. Not surprising it doesn't work flawlessly...
The 14P BIOS is also labeled as BETA. Again, no guarantees ...
