Ok so, a few weeks ago we had some power outages, I flipped the switch on the power strip before it came back on the last time, powered flipped a couple times prior. A few days passed and I flipped the switch back on and realized I had forgot to the turn off the switch on the back of my PC.

Turn the PC on and all is fine, I have a keyboard 🎹 hooked up to it and I turned that on, immediate bsod. Realized that was the cause and unplugged the USB. No problems again until a couple days ago. Was playing Elden Ring the night before and turned it on again the next day and it won't get past an immediate bsod with the WHEA_uncorrectable_error. After 3 it does the usual preparing PC repair or whatever but it usually crashes during the memory dump and won't actually make it to anything meaningful.

I can go into bios fine and it runs but anything else and I get the same error. I'm aware this error indicates a hardware issue but having trouble figuring out what is actually the problem

Things I've tried that didn't work in no order:

Ram out and back in

Ram individually (It only actually started with the one, doesn't start with the other and hangs with the ram QLED lit, thought this might be the issue but...)

Ram different slots

Roommate's ram (also checked my ram in his, and it worked fine)

Roommates power supply

Cpu reseat

Video card reseat (couldn't get it fully out, **** clip is tough)

Removing added FireWire card

Removing nvme ssd

All other hdd/ssd are disconnected

Boot from USB (works on roommates PC, same error on mine)

Popped the cmos battery and reset bios

Fixed bios settings after that didn't work
 
No updates besides not noticing any scorch marks. I ordered a new (used) motherboard to see if that's the issue. It'll be here next week. Same mobo that I have
 
It came in, no change. Tried a different gpu as well, same thing. Leaning on it being the CPU at this point, only thing I haven't tried. Can't afford one rn tho unfortunately

I made a Linux USB to boot to as well to run prime95, it hangs part way on startup, and it worked on another pc
 
so you have tried another mobo now, and another PSU and memory, so yeah - could be the CPU.
but what about trying another drive?
USB drive? Or just general storage? The nvme ssd that I had in there is out currently and no other hdds or ssds are hooked up. Just was trying to boot with only the USB
