So tonight my system black screen while mining. I rebooted and everything worked fine when idle or doing web browsing. After a few minutes running a game or mining it would black screen. When I start up Tomb raided it works til gets to the option screen before black screening. When I start up older game like HL2 it runs without issues. I have not seen any artifacts. It started after a windows update but seems like it's a coincidence. I tried different driver and even a clean install of windows 10. I am going to say it is the gpu but I will dig out my spare PSU tomorrow to do more troubleshooting. It powered this system with no issues. CPU and GPU are under custom loop. Temps are fine.
