I have a very similar motherboard - an A7n8x-x, a cheaper & less 
spec-ful version, and haven't come across behaviour like that. Apart 
from needing a bit of initial prodding to work with Debian it's been as 
stable as I'd want.

The bit about entering the bios and exiting it without changes makes me 
think perhaps the bios side of the motherboard itself may be falling 
over from time to time - and being such a core part of the machine just 
bringing down everything with it. PC Hardware isn't my forté though, so 
that's little more than a guess, and I wouldn't know how to test for 
those problems either.
