Have you ever had New Vegas crash while trying to play? Of course you have. We all have.
We may have a solution for you: NVAC. NVAC (short for New Vegas Anti Crash) is an NVSE plugin that implements structured exception handling and sanity checking to reduce frequency of game crashes.
Use Nexus Mod Manager or FOMM.
Or do it manually, in which case since it's an NVSE plugin, nvac.dll goes in your Data\NVSE\Plugins folder.
