Question Random blue screens and restarts after upgrading amd cpu

[Darkfade]

Hello, Ive recently upgrading my 4 year old system and I have been facing a problem. The pc works fine in regular applications like chrome, etc. but in any game like rust, whenever I tab out to look or click at something on my second monitor, the pc either restarts or blue screens.

My old specs were:
Ryzen 7 3700x
16gb Geil 3200mhz
B450m Steel Legends
Gtx 1080 ti (bought used)
550W Tuf Gaming psu

New Specs:
Ryzen 7 5800x
16gb Geil 3200mhz
B450m Steel Legends (Updated bios(4.0) to support 5000 Ryzen)
Rx 6650 xt (tested with old cpu, no problems)
550W Tuf Gaming psu

I have a fresh installed windows 11 so it cant be the nvidia or previous drivers screwing with the pc stability.
already talked to amd and got no where with their support.

Ive looked at the errors in Event Viewer and Im getting errors like:
WHEA-Logger - A fatal hardware error has occurred.

Component: Memory
Error Source: Machine Check Exception
