Fix: Fallout 4 Crash on Startup

Fallout 4 crashes immediately upon launch. This issue has persisted for a while now and there may be many different reasons behind this. Users report that after they deleted some specific files/folder, the problem went away only to return again after some time. Therefore it is recommended to troubleshoot the problem at its core and not resort to temporary methods.

Solution 1: Repair Corrupt System Files

Download and run Restoro to scan for corrupt files from here, if files are found to be corrupt and missing repair them and then see if it has stopped crashing, if not proceed to Solutions below.

Solution 2: Disabling the anti-virus

Anti-viruses are known to conflict with various Steam games. To make sure that your antivirus isn’t doing the same, either disable your antivirus or add Steam in the whitelist. After performing the required steps, right click on Steam and chose ‘Run as administrator’. For a detailed guide on how to whitelist Steam on your anti-virus, click here and see the first solution.

Solution 3: Updating your graphics drivers

Because Steam keeps rolling new updates every once in a while for its game, it is advised to keep your graphic card up-to date all the time. However, there is one instance where updating your Nvidia drivers will start causing problems for Fallout 4 and cause it to crash. The driver updates are labeled as 358.91, 358.87 and 358.50. If you have any of these versions, you should downgrade back to 355.98.

To check the version of your Nvidia, follow the following steps.

  1. Right click on your desktop and select Nvidia configuration panel.
  2. Browse over to ‘help’ and then ‘system information’. Here the version of Nvidia driver will be listed.

    Or if you are having difficulty in this method, try the one listed below.
  3. Press the ⊞ Win(windows) + R key to bring up the run window.
  4. In the dialogue bar, type ‘dxdiag’.
  5. Chose the display tab and you will be able to see the version.

If your version isn’t correct, you can head here and search for 355.98. Download the driver and install it.

Furthermore, if you have an AMD driver you can update it using this link.

Solution 4: Changing some options

In some cases, Fallout 4 might be crashing because of some settings. Here is a checklist for you to ensure that a problem like this isn’t interfering with your game.

  • Set the game resolution the same as your desktop resolution.
  • Run in windowed and borderless window
  • Run on high performance in your battery/power settings.
  • Uncheck Enable Intro Video.
  • Uncheck Enable God rays.
