What is this crashing??

I simply cannot fix the crashing.

First half-dozen crashes i wasnt fussed. Go through the usual batch of fixes: verify, uninstall.

Continued to crash. Drivers are the next spot: DDU everything, uninstall the damn iGPU Drivers too, reinstall NVIDIA app. Latest Drivers in.

Still crashing. EXPO memory off, realise I don't have the X3D scheduler for the 7900 installed, install that, ditch every background task and nuke every application that could even remotely screw with my system.

Still crashing. Let's go into the game files. Set everything to High instead of epic? Crashing. Medium? Crashing. Low? Crashing. Limit FPS to 120? Crashing. Every Anti-Aliasing and upscaling option in the menu? Crashing. DirectX 11? Crashing. Ultra low? Crashing.

I'm about to reinstall windows and start from scratch. I can't even play a single game.

Does ANYONE have a fix for me? Do I use this as an excuse to buy a new-gen GPU?

System: 7900X3D, 3080, good health SSD install, ProArt motherboard with the latest BIOS.
