Machine at work crapped out again. Since my boss had OKed me to move home if it happens again I did just that and working from home now. While it's nice to work from home it's a pain having to keep starting over each time. Hopefully it stops doing it now... I was good for a whole week at home during my vacation as I left it on as a test, only started when I got to the office so I do suspect it's one of the cables there that's dodgy and don't really have time to start troubleshooting that when I know my setup at home works so don't want to start removing cables here. I find when it comes to multi monitor setups if something works, leave it alone.
If it does end up doing it here then I know the issue must be related to only when it's under load. When I had it on for a week I didn't have everything open and was not VPNed in. But I did work 3 shifts in a row and was fine...
It's weird though since when it happens I do get an event log about dwm.exe crashing and it does seem to be a common issue, seeing lot of people getting this issue too. Monitors just start flickering and going haywire and eventually blank out but the system is still running. End up having to do a force shut down.
