Alright final update. I replaced the PSU the first time, issue came back. I then did the following and got it working again, unsure which could have been the resolution. Fixed IO Shield - some tabs were in some of the sockets firmly secured all power cables and MOBO battery (was slightly loose) Reseated CPU and applied new thermal paste to heat sink/CPU. (this is most likely) I'm pretty sure my CPU was overheating as I had reseated the CPU numerous times but never applie any new thermal paste.... I had to do this twice, as the first time I had put new thermal paste, I think I put too much and the computer would still shutdown.

Welp, not sure if unsolving and posting resurrects the thread but I have to do it. The new PSU worked all last night and I just got home, turned on the machine, used it for 5 or 10 minutes, and now its back to shutting down, rebooting, open to desktop, repeat till I go mad. https://streamable.com/0djc9

I bought a brand new Seasonic 80+ Gold 650W PSU and it WORKED. Made sure by powering everything with the PSU outside the case. I guess the EVGA was faulty overtime. Thanks for the advice!

Alright, I'll attempt to swap the PSU tonight and see if the issue persists, whether I borrow my buddies or get a better quality one. Hoping the MOBO isnt in bad shape as it seems the likely culprit if not the PSU.

I've been having trouble determining the cause of issue for my home build. I put together this build about 11 months ago and it ran perfect for 8 months. About 3 months ago the computer started freezing during use and the only solution was to power down. This went on daily/every other day for a while until I updated the BIOS. After updating the BIOS the computer no longer freezes, but instead will just go black and either boot back to the lock screen or not boot at all while the CPU & case fans continue to run. The motherboard also displays an EZ DEBUG LED where the CPU LED is solid white (not much info on this out there). This issue happens daily, during any use of the PC. I can always power on, get to the lock screen, login to the desktop and perform any functions. No specific functions cause the issue as it could be idle, browsing the internet, downloading, etc. and anywhere from 1-5 minutes it will Boot/shutdown. The weirdest thing is, if upon boot-up I opened Battle.net and launched Call of Duty right away, the computer does NOT have any issue and I can play for hours. Any other function and it will boot/shutdown. I have not tested other games.

As I said, this build was running perfectly then it wasn't. My next step would be to swap out the PSU or MOBO, but trying to avoid hardware swaps.
