Question PC Has been struggling as of late, freezing while playing games I've played fine in the past?

So recently, within the last week I would say my PC has been struggling with things I've done fine in the past. For example I play VRChat but randomly my PC "freezes" while I'm starting up. Freezing in this sense means, I can move my mouse around, or touch my keyboard and the caps lock button works. A hard reset fixes it.

This is the same with Path of Exile, another game I've played fine in the past, after 5~ minutes of playtime I "lock up". Background sound of the game plays, the game freezes. My mouse can move to both monitors and mouse over things, but I cannot interact at all.

Specs:
7800x3D AMD CPU
3080 EVGA GPU
Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply
32 GB GSKILL DDR5 6000 C32 FX

Steps I've taken to find a potential issue.
-Updated my GPU Drivers, didn't fix it.
- Running Memtest86 at the moment, no errors found on 2/4 tests, still on-going
-Ran Check Disk, no bad batches
-Ran System File Checker, it caught some corrupted files and repaired them.

After System File Checker fixed those corrupted files I went right into MemTest, so I'm unsure if SFC fixed it. If it still has issues I'm probably just going to reinstall my OS, but I'd love to hear if there are any other problems I'm missing?

You forgot to mention the make and model of your motherboard and it's current BIOS version. As for your platform's ram, got a link to the ram kit you're working with?

RAM kit is - https://www.amazon.com/G-Skill-288-...nel-F5-6000J3636F16GX2-FX5/dp/B0BFGB2D2Z?th=1

Motherboard is GIGABYTE B650 Gaming X AX V2 with BIOS version F30

Full RAMTEST86 passed. Also now it's looping to my BIOS showing "No Bootable Devices Found" even though my Boot Drive is showing up fine in my Drive list.

Ran Furmark, it lasted 10 minutes before it did its usual lock up thing. Points to either GPU or PSU. However another issue is, sometimes after I have to hard restart, my BIOS doesn't detect my windows on my C drive.

I'm really at a loss on what to replace here.

If it were the PSU you would not lock up, you would backscreen crash into a restart. So GPU/Storage device seems the most obvious at this point, but if taken in context with you having found corrupt windows files with either an SFC or DISM scan that can mean the storage is fine.

Windows may have been corrupted by the RAM or otherwise to the point that it causes instability and crashing. What's odd is that you say you did a memtest with no errors. My suggestion would be to use the CPU's integrated GPU to test if its the graphics card. If we rule out the graphics card we can more easily point to windows or a storage device issue.
