Cool GTXRemove X1 reboot with 1080 .. then DDU drivers .. then test with 2080Ti Make sure if your monitor has a deep sleep mode .. turn it off See deeper dive in this thread Comprehensive Windows 10 Black Screen Trouble shooting Guide
davehudsonI have this same exact problem with my 2080 Super. I have DDU'd the drivers rolled them back to different versions but the random black outs (that crash any programs as well) occur. I can make the blackouts happen straight away when I run the X1 precision software and have also tried uninstalling this but problem persists. The only workaround is to go to device manager, right click on your GPU and select uninstall and tick the box to remove drivers. Reboot and the machine and wait until Windows automatically installs a driver. It is an old driver but it works for about 5 days to a week then you have to do the same thing again. I have an RMA but after reading your post don't think a replacement card will help so going to try uninstalling Armoury crate and disable RGP control to see if that helps. Will let you know how that works out.EDIT:- After removing Armoury Crate there have been no further blackouts. I went into bios first and disabled the automatic installation of Armoury Crate and then un-installed AC from the computer and everything is fine now. I think the problem lies with AC RGB control was doing the crashing..
