Ok PC goblins you're allowed in

My PC randomly restarts with no error screen. There is no rhyme or reason to when this happens other than I must be actively using the PC. I can be using something low stress or high stress and the likelihood of this issue is the same.

GPU: Nvidia 3060
CPU: AMD Ryzen 7 3700x
I am not overclocking.
This problem persists on Windows 10, 11, and Linux Mint.
My PC is not overheating.
I've tested the RAM with Windows Memory Diagnostics and memtest and both said the RAM was fine.
I have updated the BIOS.
I have replaced the PSU, it is the correct type of PSU.
I have uninstalled all the nvidia drivers, I have reinstalled all the nvidia drivers.
I have uninstalled WSL.
Virus scan comes back clean.
I have replaced my surge protector.
I have cleaned the GPU and put it in a different slot.
I have ran DISM, sfc, etc.
I have reinstalled windows multiple times - for a bit this seemed to help but it would start doing it again.
SSD appears healthy with checks like crystal disk

Nothing shows in the reliability checker beyond "Windows did not shut down correctly"
Event viewer offers event 18

Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error

Processor APIC ID is variable between reports
