My crashing is back so have been doing more testing.
I used the Microsoft Process Monitor tool this morning to capture all the process, registry, network and file activity that are happening while a crash happens.
Monitor file system, Registry, process, thread and DLL activity in real-time.learn.microsoft.com
I can see Windows starting up the Window Error Reporting process: PID: 30708, Command line: C:\WINDOWS\System32\svchost.exe -k WerSvcGroup
I went looking for these error logs in C:\ProgramData\Microsoft\Windows\WER\ReportArchive
All the crashes are Kernel 141 errors which refers to a hardware failure. That lead me to this thread which is a lot of the stuff I've already tried to no avail. Tried the PCMark10 test and it came through at the 97 percentile rating with no errors.
Still thinking it's a video card issue or a Windows issue dealing with a game and other stuff running in the background, but don't have the luxury of having a second expensive card to swap out and try.
Able to get a dump file from your crashes ????Thanks for that link. I guess that proves for sure it's a TDR issue.
I had to upgrade my nVidia drivers from 496.13 to 516.59 because some of my software wouldn't run on the older driver. I played on that version without any crashes which is good. I know the TDR delay is taking effect when I use my VR headset because I can see the pauses on the screen.
I supposed I could start rolling ahead driver versions to see when it starts crashing again. That would pinpoint the version where the TDR setting stops taking effect. Anyone done this already?
I also ran a 3DMark benchmark test and the result is up to 3500 from 3000 with the old drivers (v496.13) which is only halfway to the 4000 mark I had with 528.02.
