Windows 10 Black Login Screen, Please Help

Hey I've literally looked for hours to find a solution for the black screen and still having no luck. I upgraded to Windows 10 yesterday and ever since my login screen goes black although i can hear the music and click the links. I've tried running it in windows 8 and 7 compatibility mode but it dosnt fix the problem. I've tried reinstalling, turning off firewall, moving my folders around but not having any luck. Anyone know any other solutions?
