Fallout: New Vegas

"FalloutNV.exe has stopped working" Common Fixes

• Modifications made to the windows registry by certain programs, to terminate applications faster. This works to reduce the time taken between a program stopping responding and it being able to be "killed". However, this can often cause an issue in Fallout 3, Fallout: New Vegas and other Bethesda Titles where they are terminated by Windows before it can respond. Programs such as Game Booster 2 (and later versions) may make these modifications to improve performance, these modifications can be reverted in Game Booster by going to "Tools > Tweaks" then checking both "End hung applications faster" options, finally clicking "Restore > Restore to Windows default" at the bottom of the page.

• The VOIP program Mumble also has known compatibility issues with Fallout Games, simply closing Mumble before launch and then open it again once the game has loaded should suffice.
