Swapped Motherboard - NO power to PC at all

Hey guys hope ive posted in the right part of the forum (im thinking its motherboard related) im having a bit of trouble with my dads computer

Specs-
Gigabyte GA 965p ds3p swapped to 680i striker extreme
500watt generic PSU then swapped for Antec 650 watt PSU
CPU - Dual core E6320 1.8ghz
1x320 sata Western Digital HDD
1x500 sata seagate HDD
2xcorsair 800 ddr2 2gb
8800gts 320mb
2 dvd burners

Basically we were doing a swap of the gigabyte board to the striker extreme so we could run SLI with the 2 320mb 8800gts cards

So far everything went really well formatted with striker board in no worries, the ONLY problem was playing anything 3D - eg cod4, 3dmark 06, the computer would just restart itself so we though OK time for a new PSU it has to be the problem.

We went and bought a new 650 watt Antec PSU and came home hooked everything up and nothing... not a single signal that anything works at all.. except for little LED lights lighting up on the striker board...

We have a PSU tester and it was showing that no -5 volts were on the antec 650 PSU, so we swapped over PSU's and still NOTHING

We then swapped back to the old gigabyte motherboard trying both power supplies and still nothing at all

So basically we're stuck at the moment, could it possible be the RAM, or the CPU, or even the graphics card or somehow have both Motherboard just died? Or at least if one of those things were the problem should we at least be getting a signal or some power of some sort
 
Try hooking up everything including the board Outside of the case with the board on some non conductive material. This will rule out a short inside the case.

Taking off for the night, if it works outside the box, look for a standoff for the board where it shouldn't be, and mke sure the I/O shield is on right too. Good luck 🙂

I took the striker motherboard down to the computer shop just to see if they had a spare CPU to try but he didn't so im not sure what to do... Im hoping both motherboards arent dead. Will try taking it out of the case now 🙂

EDIT
Took it out of the case and both motherboards now work even after trying it at the computer shop and the striker didnt work... no idea why that was but at least the motherboard isnt dead! Will figure out why the case is shorting the motherboard thanks!
 
More than likely 1 of the standoffs,(thing ya screw the board into) is touching the actual board where it is not supposed to. Could also be some kind of grounding issue.
