Try the following, and let me know your results. I am assuming that you have the game installed in the default Steam area under \SteamApps\common.
1 ) ensure NVSE's files (.exe and four .dlls) are in the top-level game directory where FalloutNV.exe is located.
2 ) ensure FNV4GB.exe and fnv4gb_helper.dll are also in that same place; not in their own subdirectory.
3 ) move the "Nvidia fix" file called d3d9.dll to the top level of your C: drive, such that it becomes C:\d3d9.dll
4 ) right-click FNV4GB.exe and select "Send to Desktop" to create a shortcut.
5 ) right-click the shortcut and select Properties.
6 ) edit the Target field by adding a space, -extradll, another space, and then C:\d3d9.dll. For example:
"c:\program files (x86)\steam\steamapps\common\fallout new vegas\fnv4gb.exe"
becomes:
"c:\program files (x86)\steam\steamapps\common\fallout new vegas\fnv4gb.exe" -extradll c:\d3d9.dll
7 ) click the Apply and then OK buttons
8 ) right-click the shortcut and select "Run as Administrator"
9 ) cross your fingers ... and see what happens ...
