ASRock Z68 Professional Gen3 Fatal1ty dr debug gets stuck on code 53 (memory initialization error. No available memory) or code 56 (Invalid cpu type or speed) and won't post. Completely random on startup which one will show. Sometimes the board will make it all the way to code A3 (IDE enable) before stalling and failing to post.

Is this a memory, mobo, or cpu issue? I doubt it's the psu. I pulled the gpu, a 7970, and the memory, corsair vengeance DDR3 1600 8GB (2x4GB), to start without it but came back with same codes 53 or 56.

Maybe it's a Northbridge problem?

Any Idea what's going on?
