HELP! PC Crashing infinite blue screens

OK so i built myself a computer almost 1 year ago. Everything was working fine until a few weeks ago. I was in the middle of playing a game and my PC randomly blue screened and would not boot back into windows. It kept booting and giving a blue screen with a different stopcode every boot.

A friend of mine has a very similar PC so we tested each component to narrow down the issue. Swapped every single component to test each and came to the assumption that it was the CPU. Once I put my CPU into his PC, with all his components - he was getting the blue screens. When we put his CPU into my PC with all my components - it worked fine.

Sent the CPU back to where i purchased it from (aria.co.uk) they got in touch and said there was no issue with the CPU. I told them what we had done and they even said themselves that it sounds like a CPU issue but they couldn't find a fault. They tested it rigorously for 3 weeks and still no issue found, so they had to send it back.

Once I got the CPU back, we tested it again and done the same thing with a friends PC. Tested a single stick of RAM from both computers, reformatted the ssd in case it was corrupt (also tested an ssd from a laptop which we know works), took out GPU to eliminate that, tested the PSU with a PSU tester, took both overclocks off each computer in case there was a conflict, temps all seem fine, visually checked the motherboard for any blown or swollen capacitors etc and it looked fine, all pints on both sockets and CPU look fine. Built both computers and only swapped the CPUs and once again and my CPU seemed to be the only one that didn't work on both computers.

My PC spec:
Mobo: Asus z-270 gaming
CPU: i7 6700k
RAM: 16GB corsair vengeance LPX
Cooler: Corsair 100i v2
GPU: GTX 1080ti founders edition
SSD: Samsung evo 960 m.2 500GB

Friends PC spec:
Mobo: ROG Maximus 8 formula
CPU: i7 6700k
RAM: 16GB avexir core
Cooler: Corsair 100i v2
GPU: Radeon Sapphire R9 390X Nitro 8GB
SSD: Samsung evo 950 m.2 500GB

I am completely lost on what else to do. Any help or advice would be appreciated.

Thanks in advance.
 
I'd recommend you refrain from discussing overclocking (with Intel) too much....; emphasize the blue screens follow the CPU from system to system consistently....(you were very lucky to have had 2 complete systems to narrow this down, as actual CPU failures are so very rare....)

Praying it was never delidded, of course, or, you would be without recourse....(creek and paddle analogy, etc...)
