So, I have no clue what to do.

Back in 2024, I bought and set up several new parts, which while the drivers gave me issues, they haven't been this bad before.

I run an AMD 7900XT, AMD Ryzen 7800 X3D, AORUS Elite x670, 64 GB of DRR5 5600hz RAM, and have a Dark Rock Pro 4 and 4 different fans trying to cool the damn thing.

However, recently when attempting to play games I can usually play (High On Life, Fallout 76, Back 4 Blood), the system completely shuts down and I have to turn it back on.

It's almost random whether the system shuts down, three times in a row it did on High On Life, one of which was the menu, and now I'm sitting on the menu while typing this out without an issue.

Back 4 Blood shuts the system down on startup without fail and hasn't worked at all. I figured that was up to the AMD drivers themselves.

Then, Fallout 76 feels completely random as well. I'll be doing fine, then suddenly the system shuts down. Then it'll work again eventually for no ♥♥♥♥♥♥♥ reason other than it wants to.

I attempted going back to the drivers from June 2025, I attempted using the factory reset option on the 7900xt, I tried turning off fast boot for whatever reason, I tried updating to the newest drivers, I tried disabling my iGPU in case it was a heat issue and that worked for a little bit but it started happening again. I tried limiting my frames, and that worked until it didn't.

I'm at a complete loss here, I have no idea what could be happening, and just want to be able to play the games I own again.

At the times, I've often had a youtube video going, along with maybe a small discord call, and the games themselves. But this was fine after shutting off my iGPU, then suddenly it wasn't again.

My fans are ALWAYS 100%, and the reliability monitor/history only says 'Windows was not properly shut down'.

I took a CPU-Z validtion while I sit on the menu for High On Life, hopefully this helps someone, ANYONE figure out what the hell is going on.

I just want this fixed, it was hell saving up the money for all my parts, and I just want things to work again. Please help me.

Edit: Just wanted to clarify, I also installed that old 'Speccy' thing, and it only said one of my cores had temperatures, even though it said the others were working. Not sure if that helps at all either, I know the software's a little archaic.
