No BSOD, PC restarts randomly, details below, please help me figure this out.

PC:
7900XT
7800X3D
Asrock HDV m2 b650m
Corsair 2x16 7200 cl34
UD-GM 850W 80+ Gold gigabyte PSU
All about a year old
Issue:
PC randomly restarts. Just goes black screen and instantly reboots. Kernel 41 (63) in event viewer. It's been happening on and off for at least 10 months.
Sometimes i find a fix and it disappears for 3 months then comes back again. Last time a bios flash fixed it for some time for example, this time it didn't.
If i don't find a fix it gets worse and worse until my windows basically corrupts and i can't boot into it, maybe once every 10 tries and then it restarts again which then sends me into a troubleshooting rabbithole, i find a bunch of fixes, it gets better for a while, then it comes back.
What I've tried so far:
Fresh windows install
Testing Idle VS load (seems to only crash idling / light use but it could be a coincidence)
Bios instant flash (was already on the newest version)
DDU amd drivers and tried older ones that people say are stable, also tried newest one
Memtest86 (both my rams passed 3 times with 0 errors)
Changing the power socket my pc is plugged into (can't directly plug it into wall, cable is too short)
Testing each ram
Cleaning out ram slots
Reseating cables
Taking GPU out and using igpu
Installing chipset drivers manually
CPU PBO and Core boost off in bios. SOC fixed to 1.2V.
All bios settings are default otherwise, ram included, no expo.
What I've noticed:
Does not crash during any sort of BIOS state or before being fully booted. If im sitting in BIOS, nothing happens. If i'm running memtest for hours, nothing happens. Log into windows, a restart could appear within 2 minutes to 2 hours.
What I'm thinking it could be:
Bad wiring in my room. With my second monitor I had an issue where if someone turned a light on outside my room, it would go black for a second, as if it power was cut for 1 millisecond each time. Maybe connected?
Bad PSU (its 1 year old, b+ tier in PSU tier list and enough power for my system, so slightly doubting it)
Bad mobo (again, it's fairly new and the fact my PC can turn on and be used for hours at a time is making me doubt hardware in general)
Bad CPU (can't explain why it could be CPU, would be last guess)

Check Reliability History!

Is your ram running at 7200MT? Memtest86 is not the best, try running y-cruncher or testmem5 and see if the memory is stable then.

No, it's running at jedec defaults, 4800mts cl40. I flashed my bios and didn't tweak any of the ram settings.

What type of ssd are you using? Have you checked the drive health with something like CrystalDiskInfo, also run a CrystalDiskMark test to verify the drive speeds match the specs.
Also how many drives/disks are connected?
Adventurous_Being578@reddit (OP)
Crucial T500 2tb + a sata 240gb. T500 is at 97% with 0 critical errors and is marked as good, SATA is same thing but at 99%

Have you tried looking at the BSOD memory dumps to see if they pinpoint to a specific cause for the reboots?
BlueScreenView by Nirsoft is a free utility to let you open crash dump files.
Adventurous_Being578@reddit (OP)
Not yet, but that’s a good idea, i will do it tomorrow and let you know. Can the dumps point towards let’s say a direct psu problem or mobo problem, or are they usually generic errors?
neteng91@reddit
BSOD crash dumps won't directly show any issues with hardware but they can be helpful to see what process/driver caused the error, that can help with figuring out which hardware could be the issue.

Get a UPS if you suspect it's due to dirty power coming out of the wall. Aim for 1000 VA or above.
Adventurous_Being578@reddit (OP)
Will look into it, but I thought that's cope and everyone will just tell me its a hardware fault to be honest. I'm trying to absolutely eliminate any possibility that it isn't.

You've already ruled out most things on the computer AND you have known power issues with your monitor.
It's time to start considering things external to your computer.
If you want to isolate it, you can bring the setup to a friend's house and see if the restarts are still occuring.
