Your issue could be due to the software that controls your LED PC case lighting.
Check if temporarily disabling that has an effect, thanks.

Thanks for the hint, it will uninstall MYSTIC LIGHT 3 from MSI and see.
I have just noticed in the dxdiag file that the LEDKeeper2.exe process is causing a conflict.
