Dr W,
Problem is solved; fences is working 24 hours without issues.
Got lost in the noise, log files, and ran down the rabbit hole but had to climb out to solve the problem.
Series of Events
======================
- Since I was already experiencing random resets a couple of days, not consistent, then your report showed just how bad the
'OS->GPU->Monitors' communication was it made sense to pursue writing a utility, besides what you had offered, which I never used.
- After updating the system as I mentioned, I relied on the utility to check the system for events
- It showed all of those constant firing events etc...
- I assumed that the AOC monitor was still broken, since it was that one dropping in/out, but it was hard to catch it doing it, besides your report. I did see it happen a couple of times in the log file.
- Then swapped the cable & port to see if the problem followed it.
- Still had excessive events with missing data
- Found that "stack overflow" article mentioning
-- phantom events causing VMWare to crash forcing a restart, similar to 'Fences' hooked into 'Explorer', needing to be restarted
NEVER CHECKED - to see if the issue had been resolved! Assumed due to the log, as shown below, there was still an issue.
Nothing was broken
==============
- Just needed to update the GPU drivers
- AOC
-- Problem with the monitor went away
- Acer
-- no problems working with different cable and port, still using Intel onboard GPU
Red Hearing - Noise (made me run down the rabbit hole)
======================================
• Yes - the system is working at least for now, no issues running Fences, no resets
• Yes - the events are still firing behind the scenes
Check this out..
1/22/2025 13:17:22: Monitor (Change Event) Logger Started
DeviceName: #1: Fiodio AF11F , Width: 2560, Height: 1080, Primary: False
DeviceName: #2: Philips 242B9, Width: 1920, Height: 1080, Primary: True
DeviceName: #3: AOC 2752H , Width: 1920, Height: 1080, Primary: False
DeviceName: #4: Acer G276HL , Width: 1920, Height: 1080, Primary: False
Approximately 5 minutes after running the logger, events started to fire.
The monitor-sleep actually did not have a chance to happen, which is set to 5 minutes
The OS->GPU->Monitor sleep is causing the events.
- as I speculated, the OS has lost communication to the monitor or GPU port, can't tell as stated

♦ As stated the TargetInstance source is missing... strange
Hope this helps.
I'll let you know if the 'Fences - needing to be restarted' issues comes to back to life.
