Around a week ago I started up New Vegas on my second screen, which is a TV hooked by HDMI. I would press play on the launcher and after a few seconds the game dropped to the desktop. I clicked back on the Icon on my task bar and once again it dropped back to desktop. This occurred every time I tried. The game would work just fine on my laptop screen, however. I uninstalled all my mods and attempted to startup again. This time I got an error message saying something was missing and I needed to reinstall. I deleted all content in the New Vegas folder and reinstalled. I turned my mods back on and started the game, not on my second screen but on my main screen. This time the game crashed as soon as it started. Didn't even make it to the disclaimer screen. I uninstalled the mods and tried again. The game continued this trend, crashing immediately on startup every time. I reinstalled again, turned no mods on and still this continues. I am not using Raptr or any other program that messes with displays (as far as I know) The game has been working up until this point.
I use Windows 8.1
Processor – AMD A8-5550M APU 2.10 GHz

Try the game, on new install, WITHOUT ANY MODS installed. Not just activated, but installed also
Steps:
If it does, then TADA. If not, just comment. Remember, don't install any mods until you can do the steps above.
