920/REII is dead and was working just prior to switching mobo's.

Had a working 980x in the REII before I started swapping boards, cases, cpu's.

Took the 980x and put it in a REIII which went into an Obsidian WCed rig.

Went to fire up the 920/REII and nothing. No beeps, no video, just the fans fire up. ROG display shows Welcome, then goes to the timer, nothing in between?

- Reset BIOS several times, via ROG reset, also pulled CMOS battery for a while.
- Hooked up different PSU, same thing.
- Reset CPU twice, checked and cleaned contacts on pcu and board.
- Tried different memory
- Tried different video card
- Removed board from case and tried everything again (shorting?)

All with the same results? No beeps from the CMOS has baffled?

Anyone experience this before and found a solution?
Anyone have anything else I can try ? This board was functioning fine with the 980x and the 920 before I moved it to another case?
