One of your mods is just messing with the textures of Skyrim just uninstall the mods you added and reinstall one by one until you find which one is messing with your game. Then you can either remove that mod or try and fix it yourself which would be very hard without knowing exactly what to do but could be done with forum help. Edit: Also be sure when installing mods to have all requirements installed as that could also lead to situations like this.
