My pc keeps BSOD and i don't know why

[Reelonk]

Greetings, i decided to upgrade my pc from a complete build pc to a new one which i built myself. The prebuilt one i have used for many years without any problems, but when i upgraded my pc everything went downhill. I upgraded basically everything ( my cpu, motherboard, cooler, case and everything). What i kept from my old build is one of my old nvme ssd's and my graphics card. At first the pc booted up fine but after some time it just randomly bsod. After the bsod i was also taken to my bios. This has happened at random times for some days now and i can't seem to find the reason for this happening. I get different error messages for the bsod which does not make any sence in my head. it even bsod randomly while writing this post.

I check the event log and what i get the most is this:
The RstMwService service terminated with the following error:%%2684420176


What i have tried:

Booting;
i have tried booting my device from a different driver but when i tried that my pc could not find a network to connect to and i was hardstuck there.

SFC /Scannow:
i have tried scanning my hardware for issues multiple times finding nothing wrong and everything is good.

Recover PC:
i have tried restoring my pc which did nothing except wipe everything from my pc and i still get bsod.

i have no clue what is happening and i feel like i am helpless.

Any help is very much appreciated.
Thank you
Thomas

If the PC will boot, follow these instructions. Skip steps #4 and 5. Add the info to your next post.
