black screen after switching between skyrim and other apps ex: spotify

[NTRTofu]

I started modding Skyrim again after they updated the .640, I don't know much about modding and problem solving, but, I had managed to get decent scenarios and nice customization.
Beyond the Gooners mods on my library, I don't understand why Skyrim ends up on a black screen when I change applications, i switch between ex: spotify and skyrim then, i end with that thing.

the black screen affects the whole pc, i can switch between desks but in the first one where i got the black screen it stays like that, so, in the second one i use task manager and shut down the game
