I had the same 00 on the bios on Sunday on a fresh build.
I removed the water block and reseated it bingo issue resolved.
This morning I couldn't get to bios again ........ didn't look at the codes though as it was working last night and all I did was move the box and swap monitors ..... I ain't gonna be worth a crap here at work today.
