For somekind of reason I get get blackscreen (backlight doesn‘t work) after installing latest Ati Crimson drivers for 7450m GPU when turning on Dell Inspiron n4050 laptop. Sometimes unplugging power cord or waiting would give randomly normal view. Only intalling older Ati drivers would resolve this problem but Microsoft basic driver is being utilised instead and GPU doesn‘t work properly. OS Windows 8.1 64
