Thanks, Bizman.
The main hindrance to resolution of this issue for me was that all the while I would see the intermittent screen freezes the OS would perform the graphics driver resets fast enough that the TDR timeout threshold wouldn't be exceeded thus I never would get the .dmp file generated in AHIII, thus there's nothing to use to go on to try to TS so I went the old trial route and shut down all programs 1 by 1, check to make sure all was actually shut down, reboot then run AHIII to see if the freezes would reoccur to try to isolate it. I had actually shut down the Logitech Setpoint software during that process thru Apps in Windows Settings but this in itself doesn't actually remove the actual Logitech mouse drivers that were installed unless you do this in Device Manager but as already mentioned wasn't any .dmp files generated to cue me in. The other random AHIII .dmp files that I did see generated prior were found due to my usage of the MSI AB\HWINFO32 combined overlay that I use to monitor my system operation while flying AHIII Dx9 version only, Dx11 version of AHIII had no issues w\ this (I use the Dx11 vers exclusively). A quick upgrade to the latest vers of HWINFO32\MSI AB software to cover the Rx Vega 64 vid card and the Win 10 ver 1709 OS fixed that so I was again left clueless until the last 2 .dmp files appeared.
If you would note that in the 2 .dmp files I posted the ID code in both files are identical which pointed to a singular, repeatable event. Since I've come to understand that most .dmp events are usually associated w\ software operation being affected by or in some conflict usually w\ a driver's operation, when I noticed the Logitech Setpoint icon in the notification display a double icon after each event occurance then reset back to a single icon after a few seconds I restarted AHIII and ran it for quite some time w\o issue. It was after noting this behavior is when I started to focus on the mouse driver as being suspect w\ AHIII
only while the game was actually running as I had no issues w\ my trackball's operation or w\ the Logitech Setpoint software otherwise......as you have alluded to in your post.
Since Hitech & Co use all default OS criteria when developing AHIII it's only academic that the default OS-supplied mouse drivers should be tested\verified to work smoothly w\ the game client so I made the switch......................
