My Notebook is HP ENVY 4 which has INTEL and AMD 7600M switchable graphics card.
After updating Win 10 1803, it can't login the windows and occur the black screen.
I need to remove all graphics card in safe mode, then i can login windows.
also, i try to install the latest graphics driver 18.5.1, it will auto download 15.7.1 to install.
Thus, it will happen the black screen again.
