I'm almost certain that the problem is not an underspec on my PC. I've got a 2.4ghz quad core processor alongside 4GB RAM and a GTX280. I could see it possibly be lacking SLIGHTLY, but that would just cause the game to lag rather than crash altogether. The clean save problem seems a LOT more likely to me.
I took your advice and started a new game with the world texture pack on (alongside the hi-res weapons and armour you produced). Game closed while I was still in the opening scene, in the cart. I've tried it 3 times. All 3 times the game has closed at the exact same point. While the thief is saying "Damn you, stormcloaks. Skyrim was fine until you came along: empire was nice and lazy.", it closes when he is halfway through the word "and". The first 2 times I had the graphics settings on ultra, then I decided to just check to see if it was a problem with my PC not being good enough and put them down to medium.
@Hockeyt0wn13: how would I go about properly getting rid of these mods then? Presumably just by deleting all of the added files from my data folder, but I never looked at the folder before modding so I have no way of telling what files should be there for the vanilla.
Thank you all very much for your help so far, btw. I may seem pessimistic, but I am very grateful.
