Ok, so you have several mods, they are most likely loose files, and by this term I mean they are not in a BSA file. You should download "Optimizer Texture (or Texture Optimizer, I know they wrote it like Yoda)", which is available here on the Nexus, after you have downloaded it, set it to look for files in C:/ (or whatever drive letter you installed the game to) Program Files (if you have a 64-bit PC this will say x86) /steam/steamapps/common/skyrim/data/textures. Then click the button that says "Start", let it run, and this should help improve loading times because it makes the files you currently have smaller, which means that Skyrim should be able to process the files quicker after you run this. P.S. This may look like a lot of info, but it's actually quite simple, and no I'm not a computer genius, or an adult for that matter, I just learned stuff from trial and error.
