@coinits You should try to hook up a differnt psu. Simple thing to do and you don't need a big one, just enough to run 2 cards to verify if its the psu or not. 450-500w should do it.

What kind of risers are you using?

I'll try the PSU. I have a Corsair 750 that works fine. There are no risers. I have a GA-X79-UD3 from Gigabyte which has 4 slots.

Are your cards ones that are mb power only?
If so that might be the issue. Too much power on the mb

Nope they powered by the PSU. This rig was spec'd out on here and this worked perfect for over 1 month.

Have you tried pulling them all out except for leaving in two and trying just these two GPUs?

If this works add a 3rd, etc.

But would be curious to know what happens with only 2 cards physically present in the computer.

It crashes the computer after about 3 seconds of mining. I am going to rob the computer that I am typing on of its PSU and try that and see if it eliminates the problem. It is a 750. The Corsair 1000 in my rig was DOA when I got it so I had it replaced and it worked but now I am going to try and see if it went kaput. I am not a fan of this hybrid fab technology in these new Corsair PSUs. I regret ordering it.

So I tried this again and looked at the MSI Afterburner reading for GPU 2. It did not matter which two GPUs I had nor which slot I had them in. The 2nd GPU reported power of >63,000% (yep you read that correct) Looking at the back of the PSU there are two connector holes on the 24-pin connection where the black plastic surrounding the holes is slightly melted. I needed a light and magnifying glass to see it. Right now I do not know if it is a symptom or a cause and the only way is to take out the PSU from my other computer and test it. Problem with that is that it is not modular so will be a pain in the ass to disconnect. Also I am worried I may fry it if the PSU is not the problem.

I may just wait until next week and go buy a new PSU locally. That way if it fries I can exchange it/get refunded quickly.

This pisses me off. It could have caused a fire.

EDIT: The damn metal on the pins both male and female ends is obliterated FFS! Damn what happened?

EDIT 2: At least it did not fry on the motherboard end. I am thinking that the PSU failed me.
