If you have much cc, you could try the 50:50 method:
Take out half of your cc, start the game, game runs fine, put back in the half of the half (so... one quarter...^^) you have taken out previously, start the game, game runs fine, and so on, until your game wont start anymore. With this way you "only" have to figure out which mod of the last batch you just put back in your mods folder is the one causing you trouble...
