Have you installed all available upgrades from Windows Update? This would include the relevant 'Optional' updates (netframeworks and C++ included). If this hasn't been done...forget trying to install AMD drivers. And we are assuming you already have SP1 installed.
These are the correct graphics drivers for your laptop > Mobile Download and save them to your desktop.
Download and save these Intel drivers to your desktop > Download Intel® Graphics Driver for Windows® 7*, 8.1*,10 [15.33]
Using your computer 'remove a program' (in control panel) "Express" uninstall 'all AMD software...including the installer. Then uninstall the Intel drivers.
Reboot and install 1st the Intel drivers. Reboot. Install the AMD drivers. Reboot. You should be good to go. Again..the first thing to do is install the updates for your computer from Windows Update.
