Downloaded and used Skyrim Mod Combiner to download all (or pretty much all but 2 or 3*) of the graphical mods it suggested, seemed to package fine except for some errors. Downloaded other mods (see this link: http://www.mediafire.com/view/tl4lo24pdf3rd8k/Nexus-Mods-Skyrim.txt.

The problem: Works fine except I can not leave the end of the cave beneath Helgen, not by Console command or walking out into Skyrim, gets to a loading screen fine and stays there for a while and then crashes to the desktop.

* - The mods I didn't download were:
- Bumpy Inn and Shop Signs v3
- No Snow under the roof (seems less immersive, but that's for some other time)
- Spell Tome Books Rexture
