Muy Skyrim gets stuck on magic combats

[KingstonPrince7]

I don't know whats wrong in my Skyrim but when I'm having a magic based combat my game starts to get a little bit stucked and few moments after my game it's officially stucked, I still hearing the sounds and music of The game but nothing else hapens, I don't know what could be my problem or if I'm expressing my self very well, can some one help me?
