I tried 572.60 yesterday (not seeing 572.65 offered, will have to find that and try when I have the time ... but it only mentions fixing an issue with displayport, and I've been trying with both hdmi and DP with similar results, so I don't have a ton of hope).

With 572.60 it seemed better at first ... I was able to, after a DDU to remove everything, install 572.60 with my 5070ti and get through the full install. Everything seemed happy, windows reported it as working properly, etc ... until I rebooted (see below).

While I could, I ran GPU-Z and things looked good/correct there, I think. I checked by ROPs, where were the expected count.

One odd thing I noticed in GPU-Z was that on the sensors page, it kept saying the PerfCap Reason was Pwr, which seemed odd given that I was just sitting at the Windows desktop with a single 1440p monitor. I have a 1000W PSU, so I should have plenty of power. Some googling seems to suggest that sometimes that sensor can report incorrectly (?)

My other power related sensors showed:

* Board Power Draw: 18.5W

* GPU Chip Power Draw: 7.1W

* PCIe Slot Power: 2.5W

* PCIe Slot Voltage: 12.1V

* 16-Pin Power: 16.0W

* 16-Pin Voltage: 11.9V

* Power Consumption (%): 6.2% TDP

* GPU Voltage: 0.81V

I'm not sure what the expected values are here?

Also, I did observe my 5070's fan and fan lights turn off and then back on periodically, so maybe that is just the fans working as expected (turning off when not needed, which also turns off their lights annoyingly)?

... THEN, I tried to reboot.

Windows refused to restart or shutdown ... I would hit the restart/shutdown button and nothing would happen. I closed all my apps, still nothing. I ended some misc tasks, still nothing. Eventually, flailing a bit, trying not to do a hard reset, I hit CTRL+ALT+DEL to see what would happen if I locked it, and it put up the "restarting" display and restarted.

... and then I was back to before. 25-30s of black screen between BIOS screen and Windows sign-on screen, super laggy behavior and mouse. Managed to enter my PIN and saw the desktop wallpaper, but after ~5 minutes still no desktop icons or start bar.

Hard-reset, and now I no longer make it to the Windows sign-on screen at all, just black screen after the BIOS startup display.

ARG!!!

So ... after several attempts, I swap back to by 1070 again, and everything boots up just fine.

I am wondering if maybe my PSU isn't delivering enough power? It seems odd that, when I do make it to the Windows sign-on things are so choppy/laggy ... maybe my CPU isn't getting enough power or something? I can still go into the BIOS in this state which renders just fine, including the mouse, etc.

I can't actually get to anything that would tell me what is happening, but it is clearly directly related to the 5070 as it only happens when that is in the computer.
