Random shut downs, no bluescreen

[Simply Introverted]

UPDATE: so apparently there was an issue with my PSU after all, after swapping it out for the PSU from my old rig it booted up and worked properly.

 

 

 

 

 

Specs:
i7 6700K at 4Ghz (was i5 6600K at 3.5 Ghz)
Corsair H80I v2 
Crucial - Ballistix Sport LT 16GB (2 x 8GB) DDR4-2400 Memory
Gigabyte Z170 X gaming 3 motherboard (was Asus Z170-E)
MSI Armor OC GTX 1080 (swapped for R9 280 then swapped back after testing)
Samsung 850 evo 250 gig ssd
Seagate Barracuda 1TB and Western Digital Caviar blue 2TB HDD
EVGA 650 P2 psu
TP-Link Wireless Dual Band PCI Express Adapter (TL-WDN4800)
Windows 10 Pro 64-bit

 

so for the past couple of months my pc has been shutting down after a bit of use, straight to black screen, and then going into a seemingly infinite turn on/turn off pattern, I've tried replacing everything except for the ram (I did try only using only 1 stick at a time) and PSU (tested the psu using this: https://www.amazon.com/gp/product/B005UZHB6G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1   PSU is working properly according to my results ) I have tried re installing windows and de-fragmenting my drives, I have tried turning it off and on again, I even tried using my pc in a different room of my house. Using Speccy to monitor temps the cpu idles at 24C and the gpu hovers around 40C. I would appreciate any and all help thank you.

 

Sorry for iphone camera quality, and the mess.

I'm actually having an issue very similar on a socket 775 board and a q6600, but I think what happened is I burnt out my CPU with too much voltage. I've swapped cards, ram, and two new psus. I can run memtest indefinitely, but trying to boot any OS bootloops me, win7, win 10, Ubuntu live, clonezilla, anything. 

 

Although I would certainly like to see if you find a solution, it may teach me a thing or two. The system is decommissioned now, but its a sentimental build and I'd like to keep it alive.
