Googled issue, found source of problem was drivers. Problem not resolved. 

So after downloading windows 8.1 (NOT recommended,) the system clashed with an Nvidia driver and caused my OS to completely crash, forcing me to re install windows 8 TWICE. Now after re installing all my drives WITHOUT windows 8.1, my second screen won't display, my function buttons won't work, and my sleep screen is just a black screen (still lit up) with the mouse curser still on it. How do I uninstall drivers and go back to earlier versions?
