A fatal hardware error has occurred.

Reported by component: Processor Core

Error Source: Machine Check Exception

Error Type: Cache Hierarchy Error

Processor APIC ID: 9

Specs:
CPU: Ryzen 5700x
GPU: AMD 5700xt

RAM: 4 x 8GB Corsair Vengeance 3200mhz

Motherboard: ASrock x570 Taichi

Hi, my pc has been restarting while playing games (the 2 main culprints being GTA 5 and Rainbow 6 Siege). Every restart has this error just a different APIC ID. I have tried running default bios settings, underclocking my cpu from 3400mhz to 3000mhz and increasing voltage to 1.25v, disabling Core Performance Boost and Precision Boost Overdrive, updating my windows, graphics drivers and my chipsets. I have even replaced my cpu (previous one was a 3700x). If anyone could help my specific case, it would be greatly appreciated.
