Is the new motherboard the exact same model? If it's a different model, even slightly, you might want to try a fresh Windows install.
It's exactly the same.

Agreed. A fresh Windows install can do wonders.
This is a really weird problem, I would try a different PSU at this point. If I read the thread correctly you haven't done that yet, right?
Right, but I just think that can't be it. The system would run for months no problem before and only hang on an OS update; now the graphics card is not recognized at all; that's not the PS.
I don't really know the full history of your build or the problems you've had with it, so you have to read my replies in that context.
However, I believe you said that the system still runs fine without the GC right? The symptons you describe seem unlikely to be cpu/ram related, and given all you've done to rule out software issues, the obvious hardware issues(mobo, gpu), what changes when you add the graphics card? What stands out to me is power consumption, and a possibly degrading/slow-failing power supply.
If you really don't want to get a new PSU yet, I can think of a couple other things you can try first.
Remove the graphics card and stress the cpu with prime to see if it's stable at max load.
Run memtest to rule out anything memory-related.
Good luck, I hope you figure it out.
What the hell. What is it going to take to get a stable system?
Craig, how long are you (and do we) have to put up with you using an obviously-flaky walking-wounded faulty-hardware PC? These issues that you're having, are not "just Windows".
At this point, I would replace the whole PC wholesale, and chalk it up to experience that your PC build didn't work, for whatever reasons, without assigning any blame.
I'm just saying, you've (seemingly obviously) got flaky hardware, even after replacing two main components (mobo and GPU - were they RMA'ed or re-purchased?). At this point, what's it down to? Either CPU, RAM, or your Windows install (or the storage drive).
I mean, if you moved the GPU to the other slot, then Windows should have detected that, and auto-magically re-installed drivers. At worst, if you manually re-install the (AMD) driver package, does it "take", and show something other than the MS Basic Display Adapter?
Why aren't you putting the video card back in the other pci-e slot that seems to work? If the card is identified correctly in that slot, who cares if "someone" told you not to. Some boards only run 8x in that slot, which honestly won't make a bit of difference in its actual performance.
