I have a month old custom PC that has had no issues until today. This evening I started getting a render device lost error and then the game will also lock up and you are unable to kill it with task manager only hard reset fixes, even trying to shutdown/restart just hangs with a spinning cursor. End task is an option but it never actually closes. I can still move my mouse and open programs while its frozen but the pc is very slow.
The only thing I could find that has changed today is windows update installed kb4495667.
Things I have tried:
Confirmed all system temps are 45-65c at the time of crash by running hwmonitor.
Installed Nvidia latest driver v 430.39
Ran SFC scan to validate system files - no issues found
Disable all unnecessary startup background running programs.
Crash happens randomly maybe 30min - 2 hours apart. Crash happens on live playing arcade and quick play, and happens on PTR playing custom games. I have not tried comp since the issue started. Game is still running normally between crashes, fps is 144 and capped to my monitors spec.
