Symptoms:
- Display image freezes on last frame
- No m/k inputs work whatsoever
- Audio freezes to a square wave sound at whatever pitch was last coming out of the speakers
There is seemingly no correlation to activity level. The system can be idling on a desktop, or running a high load game.
System:
- Win 10
- All new hardware about 2-4 months old
- NVMe SSD, Coffee Lake proc, GTX 1080, Gsync Monitor, 750W PSU
All drivers are up to date.
Things I've tried:
- Mem diagnostic tool, no issues found
- Searching through event viewer: there are absolutely no events that match with the lock-up time. Events start showing up chronologically after a manual power cycle, starting with an Event 41 to indicate improper shutdown, with no further info.
- Crash dump is on, but there is no MEMORY.DMP file at all.
- sfc /scannow
- I monitor system temps, CPU and GPU are in the mid 40s during general use
I've read through Event ID 41 and this sounds like a hard hang. However, this is all new hardware and a beefy PSU with no overclocking. Cooling is fine and system doesn't even have to be under load.
I'm at a real loss for how to get any visibility in to the problem, much less what to fix.
