Fallout New Vegas Crashing When Entering Camp McCarren.

[LocoMonoco]

Well i'm trying to do all the quests for the factions that havent vilified me and i needed to do the ones for Camp McCarren and when i entered the main door i saved and tried to go into the airport part of the base and it froze for 2 seconds then crashed just before i got to the door. So i restarted the game and try the auto save it did. Crashed, then i tried my save that i did when i entered the main door. Guess what, it crashed. I need help on how to fix this. I don't know if you people need my PC specs this time so i'll put them anyways. I've been able to enter the base before though, just thought you needed to know that.

Game files might have got corrupted. You should try and re-install the game.

fallout freezes a lot for some reason that's why you shouldn't overwrite all your saves you should keep at least three . the best thing to do wold be to go to an older save or keep playing but go to a diffrent place and play for a while and then come back
