Question Bsod and power loss can't find a fix

[MaliciousKäse]

I've been working on my pc for a year or so now upgrading it from my prebuilt and after a year of upgrading just the core components I started getting stuttering and crashing. I tried updating all drivers and a system reset all data and nothing changed

I got 3 Bsods today after a power loss switch off.
- Page fault in non paged area
- IRQL not less or equal
- System thread exception not handled

I really need some help I've been trying to fix this for so long it's driving me mad lol

New parts
CPU- Ryzen 7 5800x
CPU cooler - Noctua redux nh-u12S
GPU - RTX 4060 2x fans
PSU - Corsair Rm1200x Shift (formerly: Msi MAG 600W bronze)
MoBo- MSI MPG B550 gaming plus

Replaced a 450w PSU, stock amd cooler, Asus prime A320mk mobo, Ryzen 5 4500, and Nvidia GTX 1050 from my original build I upgraded

A new Corsair vengeance pro 8gb stick paired with a pc specialist 16gb ram stick (this did not add any new issues along the way but I plan to get a new pair soon)

MoBo- MSI MPG B550 gaming plus = new motherboard
Asus prime A320mk = old motherboard
Did you reinstall your OS after the migration?

You're mixing sticks of ram? Might want to stick to a ram kit, instead of recycling the older stick of ram with the new kit. Might want to pass on links to the rams you're working with.

Not right after but I have as of now, and yes that is new and old.
However the issue presides from a year after upgrading only my GPU and CPU, I did not add any new components since then and the same issue has still occured

Just not too sure on the exact specs of the pc specialist one, I have already looked into the issue with the mixing ram I do plan to upgrade but it's mainly the fact that this didn't change anything before or after adding it.
