Are you running FO4 via Steam? If so try this, right-click on the game, properties, verify integrity of game cache. This will verify you have the correct game files. Then launch the game and the FO4 launcher should pop up before you go into the game, from there change the resolution to your native res (if needed) and change the graphic settings (IE: If set to low change to med or high) and try playing the game.
