Has this been tried? Run it on cardboard to remove any possibility of the case shorting something.

Yes I did run it out of the case, and that was before the CPU swap, and it yielded the same code

No point in trying it in another case then. The board is a goner.

Let me be clearer here, it is impossible to run the motherboard on a box since my CPU is water cooled (not an AIO) so there is no practical method for 'building' the computer outside of the case, and since the CPU is underneath an EK water block, switching to air cooling just for testing purposes would be a huge undertaking. I and my roommate have gone over every inch of the board with a high powered flashlight and there is no evidence of burnt traces, blown caps, etc. The motherboard still gets power as is indicated by the fact that everything lights up.

You can test the board with the new cpu on cardboard without the water cooling at least long enough for it to POST. If it POSTS, shut it down and you know there was something shorting the board in the other case. Or just build it onto the other case I guess. I suspect you will see the same results regardless of what you try.

I'm facing the same problem, and I've noticed you've encountered similar issues. Were you able to overcome this problem?

Any update? 

I have the same problem, the board looks fine, the cables look good, I didn't make any changes to the computer for several years and suddenly one bright day it happened, I changed the CMOS battery, updated the bios, nothing works... I don't want to change the motherboard, processor and RAM now and find out which in the end is something that can be easily solved

I bought a new motherboard and then discovered that the issue was most likely the riser cable for the GPU, I have not tried the old motherboard again, but there does not appear to be any damage to it.
