Rig:

SLI 3GB 580's
2500K @ 4.5
8GB Vengeance Ram

I have the annoying crash to desktop / freeze up issue with my copy of skyrim, and it has been like this for over a month now, and I cannot for the life of me figure out a solution for the problem.

Possible causes as I can see, and I would greatly appreciate other suggestions Crashes never happen in caves or indoor cells, always, on fast travel or when outdoors.

Save file too big? 10.3MB

Load order wrong? Although I am using NMM which as I understand uses BOSS.

Those are under plugs, I have other mods not listed there in the mods tab.

Vram isn't an issue, so it surely, can only be load order (as it happens when I am fast travelling and the rig is loading a new scene?!?!)

Any ideas lads?
