Without Intel HD graphics, my HDMI wasn't working and I couldn't reduce or increase my brightness.
Anyways after searching around and getting no help or solution from the internet, and trying to install countless drivers from Intel (I even tried the automatic driver updater) and getting many error messages. I finally fixed it.
I stumbled across another Intel HD graphics driver http://drivers.softpedia.com/get/GRAPHICS-BOARD/INTEL/Intel-HD-Graphics-Driver-15333643309-for-Windows-8-Windows-81-64-bit.shtml I decided to give it a try and it worked. I restarted my laptop and found that the Intel hd was there alright and my graphics memory had increased to 1gb. The pes 2016 was still slow though not as before. I then tried some of the latest drivers I had downloaded earlier from Intel that refused to install and one of them with the same number as the one from the link above worked this time, so it was basically an upgrade. I restarted my laptop again and found that my graphics memory had increased to 2gb and the games, HDMI and brightness worked fine. So relieved!
