KMODE Exception Unhandled when installing windows 11

FULL PC SPECS:
CPU: AMD Ryzen 5 5600X
Mobo: NZXT N7 B550 (new), Asrock B450M HDV r4.0 (old)
RAM: Corsair Vengeance LPX 32GB 3600MT/s
GPU: AMD Radeon RX 6600
PSU: MSI MAG A850GL


Hello all,

I built my own computer a few years back and it worked great until around a year ago when it started crashing completely randomly (no matter the load).

I tried several different solutions following advice online and managed to fix a few of the crashes that were happening by replacing psu and wifi card (wanted to upgrade anyway), however one persisted. Essentially four blue screens would show at the same time, making each unreadable. When checking the windows error logs, it would say “kernel power 41”.

This led me and my friend I am working on the computer with to consider the motherboard. After looking online, we found a few people with similar problems and the same motherboard (asrock b450m hdv r4.0). Luckily, I had a friend who had gotten an extra motherboard shipped a while back (NZXT N7 B550) and decided to pick that up and try it.

This leads us to the most recent events. I tried initially to swap all components to the new motherboard, however this immediately resulted in the same crash from before, then a boot loop with a BSOD “SYSTEM THREAD EXCEPTION NOT HANDLED”. I backed up all of my files to another drive (m.2) than my boot (SATA SSD), so decided to see if a fresh windows install would change anything. After the initial install was complete, and the computer restarted for the initial boot, it gave the BSOD error “KMODE EXCEPTION NOT HANDLED”. Even tried updating the bios to the newest version after this.

Seems somewhat likely it could be the new motherboard, however would still be left with the random crashes that led me to try swapping the mobo in the first place…

I have also tried:
Using only one stick of ram (both sticks)
Using an older ram kit
Disabling CSM
Turning off XMP
Windows startup repair
Windows reset
Starting in safe mode
Using old motherboard again (works ok, but won’t solve the issue with the random crashes)

Thanks for taking the time to read the post. Any help would be appreciated.
