The system has rebooted without cleanly shutting down first.

Hi all. So for the last few months, I've been bugged with 2 weird issues:
Video_TDR_Failuer (116) and Kernal 41 power issues. Both crashes do the same thing, restart my pc

It started here: VIDEO_TDR_FAILURE (116) - PC locks up or restarts

After the above post I did a few weeks ago, I decided to do a clean install of windows.
Before I did anything, I completely updated all my drivers to rule that out. I also decided to update my bios. I realised that my BIOS version was a beta, and was taken down, so fully updated my bios to the latest, stable version.

Everything has been great, up until today.
So as I usually do, sometimes I just leave my PC running, and when I come back to it, the screens are black, so I'll hit enter on my keyboard, and it usually wakes up, but today, it took a few seconds longer than normal, then I see that my whole PC restarts.Initial thoughts...great.

I load up event viewer to see that I have the Kernal issue again. As I start googling it, my computer restarts again. Same error. Once more, I open event viewer, same issue, head over to google and this time, my pc just locks up completely, stuck on desktop.
So I did a hard reset and walked away, but as it was playing on my mind, here I am.
Now, so far so good, it's been on, without a problem for 30minutes or so, so maybe it just needed a hard reset, but I'm here asking, anyway.

So what have I done.
Well, since a fresh install a few weeks ago, I've not overclocked the CPU or GPU. I have auto overclocked the memory.
So right away, after the install, once all drivers were up to date, I ran memtest, and it passed on all 4 tests, so I am happy it's not a memory issue.
I ran some strenuous tests on the PSU, CPU and GPU, and everything seemed fine.

The only thing that as of today I haven't done, is install the latest GPU drivers and one windows update, which is:
2021-11 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 10 Version 21H1 for x64 (KB5007289)

Both of which, I will update before turning my pc off.
I've done the V2 log, so hopefully that may show something up.

The only thing I did today, was install L-Connect. A Lian Li piece of software for their fans. It could be to do with that, I guess, but I did plenty of googling, which came up with nothing.

So, any help you can offer, or any suggestions, I will be thankful

Also, my current windows version is: 2181 build 19043.1348

Did you try to replace your graphics card with another one?

I've not done any hardware replacing as of yet no. To be honest, my computer is custom watercooled, so changing any parts is quite impractical unless last resort.

It is a new card though, only 8months old. I know things can fail, but I've lest strenuous tests on the machine and it's run smoothly, these 3 crashes last night where the first in about 3 weeks, and all 3 of them happened while using chrome, or in sleep status, so I am really hoping it isn't this
