After update, video won't wake up

[PineyCreek]

Basic troubleshooting issue: roughly since the time the fall creator's update (1709) was installed on my Win10 desktop, the display will not wake up sometimes.  However, here's the circumstances:

 

1) Asrock X370 Taichi BIOS was updated to 3.20 around the same time

2) Power plan is set to never put the desktop to sleep, but display is set to sleep after 30 minutes.  Hard disk also set to turn off after 30 minutes.  Note I am using the High Performance Plan, not the Ryzen-specific plan.  I've been using the HPP without issue until recently.

3) All USB input peripherals such as mouse and keyboard are set to wake up the computer

4) Display wakes up fine after the 30 minute timer.  The failure to wake up is not consistent...but if it does happen, it's always after the system's been sitting idle for hours.

5) Two displays connected, neither show image.

6) No issue with reset, screen comes back, nothing in windows events that appears to indicate an issue.  No issues ever during active use.

7) 'Fast Startup' has already been disabled

 

Specs:

Asrock X370 Taichi board, Ryzen 1700, EVGA 1080Ti FTW3.

 

I'm like 98% convinced it's software, but I'm not sure what else to try save completely disabling the display from turning off in the power plan and leaving the system alone for a couple of days.  Any other suggestions?

After troubleshooting further, I can see that the system will freeze even when the system is set to not turn off anything to save power.  Image is frozen on the screen.  Still not sure if BIOS or video driver issue with FCU though...likely not the driver though considering the lack of complaints, and I've already updated the nVidia drivers as well post-FCU.

 

Anyone know if there's a potential hazard rolling back BIOS on the Asrock X370 Taichi (using the USB method)?

Don't allow anything to wake up the PC except the mouse. Try that. If the problem persists, try with the keyboard and disable the mouse waking up the computer.

Tried, made no difference.

 

Either way, apparently some people have reported full system freezes with FCU other than me.  Maybe I'll run in safe mode for a couple days to see if I have the behavior.  It bothers me since I've updated the video driver since then though... :: shrug ::.  It's minor nuisance since it only happens when I'm away from the computer.

Seems like a large number of people have this problem.  There's a few threads on the MS Technet forums about it.
