I upgraded my PC to Windows 11 and am now getting this in the event log and the computer just crashes (no BSOD) - just does an immediate reboot.
Sometimes it would reboot within seconds of logging in. Most times every few hours. Sometimes it would reboot twice in a row. Same error in Event Log.
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 0
Computer Setup:
Processor AMD Ryzen 5 5600X 6-Core Processor
GPU AMD Radeon RX 6650 XT
MB ROG STRIX B550-F GAMING
BIOS defaults loaded - no overclocking.
I replaced MB, memory and even CPU - all the same results since Windows 11 upgrade. I have since narrowed it down to the AMD Graphics drivers. I installed AMD Radeon drivers 23.3.1 from March 7, 2023 and viola - the reboots and the hardware errors stops and have not occurred again for the past 3 days. Reinstall new drivers even from previous releases like August 2023 and again the crashes/reboots occur. Back to Version 23.3.1 and the crashes/reboots stop.
Can't go back to Windows 10 - so stuck with the old drivers for now - I will also probably create a ticket with AMD. Anyone have any other ideas?
