League Of Legends Client black screen on log in screen after pressing launch. (2015)

So i recently got Windows 10 and it was really bad and i think it messed up with some of my drivers but i managed to fix it . Anyhow when the updating and upgrading finished i decided to open League which after pressing "Launch" it straight away was supposed to go to the log in screen which didn't but only show me a black and empty league of legends client without anything on it not even a close button lel. So I've tried repairing it and it didn't work, anything thing but that i am now going to delete the lol_air_client and the lol_launcher and restarting my client again hopefully this works if not you will hear from me again :P
