I have a Windows 10 pc which is acting strange, I think it's AMD related. For some reason the cnext.exe application interfere the fast boot option which causes that I see mutiple error messages about the pc not properly booted, when I shutdown my system I hear a error message and for one time I'v seen a message popping up referring to cnext.exe.
So I decided to disable Fast Boot which resulted in a blue screen, so I enabled it again but the warnings were still there. Then I removed all AMD software from my computer and only installed the display driver, that seemed to work, now I don't getting these error messages again. One thing that really annoys me is that Fallout 4 crashes somethimes and I get a message about the display driver crashed and recoverd, I know there are more people with this problem so I think there is something not right with the latest AMD software.
I believe the cnext.exe error issue was resolved in Crimson Edition 15.12 driver. Have you updated to this driver?
