For the past week I haven't been able to load fallout 4 at all. The start splash screen comes up, I press play, loading splash screen comes up, then its back at the starting splash screen. I run no mods, I have added nothing to the computer, I have updated everything, uninstalled re-installed the game, same with steam it's self. I sent the dxdiag to bethesda and they sent me here with no help. I as well sent the same thing to steam and no help. Does anyone have any ideas at all?

Thanks

Would you please please post the dxdiag here.
