Hiya, first off, sorry if this is long and fluffy. I'm not good at being concise.
I've recently (Jan 2021) updated my platform from an lga1155 to a AM4 system, and I'm running into display driver/dwm crashes which freeze what's on the screen but keep the PC running.
I can hear videos/games/chat continue, and I can manipulate them. I just can't see anything.
To gain full control back I have to turn it off with the PSU switch as just smothering the power button causes it to crash at the windows loading icon, the little pale blue one, but the system continues to boot to desktop behind a frozen screen.
This is what event viewer looks like during or around the time of a crash:

I cannot figure this out. I've rolled back drivers, uninstalled all I can and reinstalled them. Tried 3 different (current, last and a few versions back) Nvidia drivers using DDU each time.
I've run sfc/scannow and a few other commands to wipe and repair Windows update and check that all the Windows files are fine, they all report that everything is fine, or that they corrected something and when run a second or third time come up clean.
I've booted to safe mode a few times, not spent much longer than a few minutes there so I can't really tell if it happens in that environment.
I've rebuilt my W10 install USB stick with an updated version from the Windows support page and run Windows start up repair.
I've tested the RAM, using windows memory tester and also using 1 stick, 2 sticks in each socket
I've reseated the CPU, and also replaced the CPU with a new one
I've reseated the GPU a few times as it's a recently new build and I had to go back to my old one for a few days during a return window(old pc runs fine, no issues)
I've reseated all cables at both ends
I've remounted the motherboard to make sure nothing was touching underneath
Basically I've taken it all apart twice and put it back together.
I've use the DP to HDMI cables between 2 machines no issues
All hard drives have been used across both machines, no issues
I've faffed about uninstalling a much fluff drivers/software as I can. So many RGB things these days
I check temperatures and make sure they don't get too high. A bit much actually, I hate how spiky the ryzen chips are.
I've checked power draw for cpu and gpu, they seem alright.
I've mined some crypto fine, bit warm but fine.
I can play games, watch videos, browse the web no issues
*after a random(?) time it'll crash no matter what I'm doing.
I want to point a finger at the 20H2 update but I've no grounds to base that on.
I found a folder, C:\ProgramData\Microsoft\Windows\WER\ReportArchive, that has loads of AppCrash_dwm.exe folders, I assume logs? I can't view them as I don't have nor can I gain permission. Odd that.
I reinstalled windows the day after I finished putting this machine together, I think to fix this same issue, but obviously it didn't work and like I said, I put together a newer W10 install usb stick. It's the last thing I want to do but I'm willing to reinstall again. It's just a bit of a let down doing all that for the same issue to raise it's head again.
More than happy to supply driver numbers or any info needed. Thank you for taking your time to read... this mess :)
