I know the CIC isn't the first place on the list for asking about tech problems; but I've reached my wit's end. I've made threads on overclock.net and on Tom's Hardware and nobody seems to be able to offer up any advice.
Since I've had good PC advice from you guys before, I thought I'd give it a shot and see what you tech types think.

Tried building a new rig yesterday and failed.
Asus P9X79 Pro
Core i7-3930k
8gb DDR3
GTX 750Ti (temporary, waiting for Pascal!)
Seasonic Platinum 1050w PSU
When I power up, the fans spin for about half a second, then the board powers off completely. No VGA, no POST, no warning beeps, just on, fan spins, then off.
Then about 3 seconds later it comes back on again, same thing, turns back off again.
This loop is endless.
Here's what I've tried
- Reseated CPU
- Reseated all power cables including CPU 12 pin: Firmly, over and over.
- No case, cardboard 'test bench'
- New lithium battery
- Different PSU
- 1 stick of RAM
- No GPU, No RAM, just the CPU and board.
- Flash to new BIOS using USB (incredible you can do this without powering on!) Shame it didn't help.
^ All of these things give the same result; comes on, goes off, comes on goes off, no post, no hint, no hope.
Has anybody got any ideas?
I tried entirely different RAM (known good) and a very basic GPU, one the doesn't require extra power. Then I made this video to demonstrate:
