It's not my mods, the game does it in vanilla as well. it's not got anything to do with graphics, i can run through everywhere in the game, even WIndhelm, without a crash, but suddenly i crash 5 times in an hour in, like, a dungeon after losing to a few bandits. whats going on?

Hi, follow the advice given in this guide, especially about memory patch and DLC/update ESMs cleaning : http://www.nexusmods.com/skyrim/mods/50244/ by FireFreak111
