My laptop dell insiron 15 3537 is showing black screen after installing intel 4400HD graphics driver & restarting i m trying to start windows 8.1 in safe mode by pressing F5 but it is also not working how i can resolve this problem..?
I have the same laptop and also had problems of this kind (black screen when turning it on, or, black screen when shuting down and it stayed that wait, black screen and all the lights were flashing) when installing drivers on Windows 8.1. What I did was reinstal it again and first install the Intel GPU drivers, reboot AND AFTERWARDS installing the AMD drivers.
NOTE: All drivers were installed from the Dell web site.
