well, my crashes were getting more frequent and now they have gotten to the point where my current save is loaded and i get about 5 seconds into the save and then i get the message that "windows 7 can no longer run Fallout New Vegas" and is shutting down. i have uninstalled the game about 4 times and reinstalled, there are no mods, just the basic game, i have compatibility set windows xp sp3, applied the .dll file to the approiate place, made the edit changes within the "fllout.ini file", don't know why i'm having this problem. not sure what else to do, any suggestions?
