I've been playing skyrim for a long time, and I've accumulated lots of mods, but due to nexus and the steam workshop, I never learned to manually install mods. In turn, I have no clue how to remove mods completely, using the data files or whatever it is you have to delete in order to remove mods. My game crashes after five/ten minutes of gameplay, and I just want to delete all my mods and start over. Help?
