No video signal...

Put together my new Z79 board and i7 on my desk and powered it up and everything worked.

Put it in it's case, powered it up and I'm not getting video signal from either the board or the dedicated GPU.

I've stripped it back to just the board, cpu, stick of ram and cleared the BIOS and I'm still not getting a signal.

If I plug the monitor in, via HDMI, DVI or VGA, (or DP using the GPU) the monitor detects something has been plugged in. But when it comes to booting the machine up it's as if the board (and GPU) are incapable of sending the signal that there is video that needs to be displayed. I can't even access the bios as a result.

Tried everything and it's driving me nuts. Any ideas? I've ruled out it being the monitor since connecting a Brix to it via hdmi and DP works without issue.

Have you rebuilt it outside the case again ?

What cooler are you using as sometimes over tightening can course issues.

Yup.

Using the same one that I was on my 8320E. Phanteks PH-TC12DX. Surely it wouldn't have worked initially outside the case if I'd over tightened it though?

Any stray standoffs shorting out the board?

RJC, you're a god damn genius. How the hell you pinned it down to that I don't know. After I posted the above I thought "can't just be the cooler is too tight", so loosened it a bit and the damn thing is now giving a signal over all ports including GPU...

Too much pressure to CPU causes CPU pins in socket moving out of CPU pads probably
