Blackscreen bootloop 3900X

Hey guys,

So 5 months ago i got my new PC.
from the beginning it had a few issues with the GPU where the PC was shutting down unexpectedly (wasnt even able to install windows).
gave it to a tech store and they said the GPU was faulty and Newegg replaced it for me and everything was working fine(ish) where i only got a rare random shutdown every once in a while...

then out of nowhere the PC started shutting down repeatedly giving me black screens while being stuck in bootloop.
i did manage to boot into windows eventually, and found this in Event viewer - 

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

- booted into Safe mode and still crashing
- tried updating BIOS and clearing CMOS.
- reinstalled every driver available for both the CPU and the GPU.
- i did manage to run memtest with 0 errors
- and i was somehow able to run Heaven benchmark without crashing the entire time but it crashed shortly after (CPU got to 80 degrees max so not overheating).
- no OC was applied since i was saving to buy a better cooler (used the stock one)
- cannot format windows because its crashing in the installation


i tried submitting an RMA with AMD global support, but its been a week now and no response...

does anyone know if theres something i can do?
the CPU is only 5 months old which is brand new, please help :(
