Update...
Completed 3 tests using memtest86 with XMP enabled... All 3 passed, however, the PC did reboot half way through the 2nd test and came up with the blue screen saying that automatic repair failed. But when I restarted and booted back to USB, the memory test continued where it left off and passed. It then passed 3rd time with no problem. Strange!
I've had the GPU removed all day now. Initially, I had no issues, no crashes, all fine. But as the day went on, it has crashed around 3 times now, usually when restarting the machine. I'm leaving the GPU out for now, but I do have a spare GPU available now to do some testing with.
I've also tried using the system with 1 of the 4 sticks of RAM at a time, swapping them in turn to test them all. No issues experienced with any one of them on their own.
Other than swapping the PSU... Any other thoughts for next step on testing? Presumably, all that will be left after that is the motherboard or NVMe drive.
These artifacts on boot with the blue screen that is some serious crap. My bet is PSU problem since I have had same thing happening. I tried everything and it turned out to be PSU. I also needed to reinstall everything.
The other thing would be the thermal pads since this seems strictly GPU problem but like i said, it might be PSU. It is hard for me to believe it is actually thermal pads due to the severity of the issue. Win boot problems? That is unlikely the pads but worth a shot.
I would check the CPU as well since, someone mentioned, iGPU has problems as well?
If you havent done it yet. Clean your entire PC. Put it apart, clean and reassemble. Clean win install and try. If your problems wont go away, try swapping PSU if you've got one spare or a friend that can lend you one.
You can also try your GPU with a friend's computer to see if it works ok if that is an option.
Just to confirm, the PC has been cleaned (was pretty clean anyway) and it has a fresh Win11 install. Although I'm considering refreshing the Win 11 again anyway, given the recent crashing and suspected corruption. I've got new thermal paste for the GPU, but as that's been out all day, I doubt that will do anything now.

Update 2:
Just as I posted the last messages, I got another BSOD.
Stop code 0xc000021a. A quick Google says this is yet another corruption!
