How to Set Fallout 4 to Full Screen
To set Fallout 4 to full screen, first launch the game and wait for the main menu to appear. Then, head over to ‘Options,’ select ‘Display Settings,’ and there you should see an option for 'Mode.' Click on it and select 'Full Screen.' Don’t forget to apply the changes before exiting. If for some reason this doesn’t work, you can try editing the Fallout4Prefs.ini file located in Documents/My Games/Fallout 4. Find the line that says bFull Screen=0 and change it to bFull Screen=1, then save the file.

Just alt+enter. Works like a charm to switch between windowed and full screen for most games, Fallout 4 included. Remember, the simplest solutions first.
Honestly, just play it in windowed mode. It crashes less, and you can easily alt-tab to check guides or whatever without the game having a meltdown.
