I have just opened a support ticket (04174081) for the following issue but three browsers on two systems won't let me upload any screenshots or the SUS report, so I'll try here:
Since updating the driver to the latest version (188.8.131.5209) four days ago, I have been getting around 5 of these hardware errors every day popping up in the reliability monitor:
Aufgrund eines Hardwareproblems ist Windows nicht mehr voll funktionsfähig.
Parameter 1: ffff820ccf5224a0
Parameter 2: fffff80e08189920
Parameter 3: 0
Parameter 4: 1a54
Service Pack: 0_0
Sorry for the German version, there seems to be no option to get an english report.
Usually I do not notice anything at all while using the system at the time of these error messages, so if they would not show, I would not even know about any issues.
It has happened twice though that a noticable event has taken place at the exact moment the error was logged:
1. I was watching a youtube video and the video got stuck for a few seconds while the sound continued playing
2. The desktop window manager crashed at the same time and the screen turned black for a second before every thing was restored by the system
Currently it does not seem to threaten the integrity of my system but it is a nuisance nonetheless.
Thanks in advance for your help
As Windows advised me about the 1809 upgrade being downloaded automatically pretty much after posting this thread, I decided to take a leap of faith and install the upgrade to see if it fixes the issue.
The upgrade has thankfully completed successfully and I will now wait and see if the problem is gone or if it persists.
