Re: ASRock Fatality - Bad Board?
Sorry to hear your problems with this board.
Grounding out? Carbon washers? Carbon, in most forms/states, is conductive. Carbon fiber is too. I trust you meant something other than carbon there.
The standoffs to mount the mb, they were placed correctly to employ all the mounting holes of the mb? No extra standoffs residing under the mb that may be causing a short?
Also, not knowing what the I/O Shield looks like for this mb, but is there the off chance that one of the tabs of the shield didn't somehow find its way into one of the mbs rear ports did it?
To me, it appears you have an unwelcome and deleterious power or ground issue going on here.
How did it test when you benched it outside the case with the minimum attached?
