WTF Skyrim!

Hey forum, I have been having a lot of problems with Skyrim on my pc lately which I was hoping some people could help me resolve. 

Everytime I fast travel or go into a major city through a gate it closes the game down instantly which obviously makes the game completely unplayable. I have numerous mods installed but my PC is still running it stably and I can't find a solution! This sucks as Skyrim was one of my favorite games when I was a console nub and I want to play the game on PC with better graphics and amazing mods! 

Any help would be appreciated guys! 

you probably have mods in conflict., remove every mods., do a clean install of da game., install mods one by one and test the game between each mod you've installed..

Here is a link to my mods if that helps:
