Everytime i start up fallout the intro scene will play and then it will go onto a loading screen and then close itself with no error code please help i really want to play

One thing I know which will make this sort of CTD, is if there is a mod in the load order which is missing a master file.

Are you using Asus gamer osd or SMart DOctor?

Temporarily disable Anti-Virus and try it.

Are you using mods?

disabled anti virus still crashed and i don't have any mods installed.

Fixed it installed d3d9.dll from nexus and it works
