after pressing launch league opens up black (win10, and new nvidia beta drivers)

the launch page works just fine.. but after I launch the login screen is black but I can still hear music and I can find my way to put in password.. when I log in .. it is black also... the program seems functional.. I clicked the top button to start a game and it made the noise.... I'm sure it has to do with the fact I installed the new build of windows 10 and I installed the beta windows 10 driver for NVidia ... I have a gtx960 asus strix
