Hello All. I am experiencing a little problem with my New Vegas install (which I have gained through Steam).

The problem is that whenever I approach the Nellis Airforce Base gates, following the fence from what I would presume is the south. I know I have alot of mods but I have disabled said mods and attempted to enter the base, yet even wtih just the FalloutNV.esm activated the CTD still occurs. I even tried it from an earlier save, I cannot fathom what might be causing it. I even placed my settings down to low to see if it was a graphical issue which yielded no results. Here are the mod files I have, I would be appreciateive if anyone can offer a suggestion on what to do.

If you're still experiencing the issue even without the mods- that would suggest that something in nearby cells causes a crash when the game begins to preload adjacent cells OR some sound/visual effect near the gate area is crashing the game.

It could be something as simple as the location music for Nellis causing a crash due to an incompatable 3rd party audio codec or maybe a corrupt entry in one of the adjacent cells. It would be helpful if you posted your DXDIAG output- that would let us see driver information and installed codecs.

In the meantime you may wish to verify your game cache through steam (unless you have been trying to avoid the latest game update or something). If you do verify game cache and 1-2 files repeatedly fail validation that isn't something to worry about. If it redownloads some of the main game data files though then that might have been the cause. If that doesn't fix it go ahead and post that DXDIAG output.

I'm downloading the files now. Verification failed on two files, which total to 1 GB in size. So I'm hoping this will solve the issue. If not I will do as you say and post the DXDIAG output, thanks for your help.
