System Requirements Minimum Recommended

Processor Intel Core i5-2300 2.8 GHz/AMD Phenom II X4 945 3.0 GHz or equivalent Intel Core i7 4790 3.6 GHz/AMD FX-9590 4.7 GHz or equivalent

Fix 2. Run Fallout 4 in Compatibility Mode

Since Fallout 4 was released in 2015, it may not be able to run successfully on some systems. Therefore, you can try to run Fallout 4 in compatibility mode.


Step 1. Go to the installation folder of Fallout 4 (You may find it in C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 (By default) or C:\Users\username\Documents\My Games\Fallout4.)

Step 2. Right-click the Fallout 4 executable and choose "Properties."

Step 3. In the Compatibility tab, tick "Run this program in compatibility mode" and select Windows 8 or other older version of Windows.

Step 4. Tick the box beside "Run this program as an administrator" and click "Apply" > "OK."

This usually resolves compatibility issues and crashes.

Fix 3. Disable All Mods

As a game with a lot of freedom and allows players to install all kinds of mods, these mods are highly likely to be the culprits of game crashes. You can disable mods in your mod manager and try launching Fallout 4 again.

If you can run Fallout 4 without crashing after doing so, reinstall your mods one by one to identify any incompatible or corrupted mods causing crashes.

Fix 4. Disable Weapon Debris and Godrays

As I mentioned above, the game was released in 2015, so one of the most common reasons for the Fallout 4 crashing is inappropriate game settings, which can be incompatible with newer systems or hardware. But, many players reported that they have successfully fixed the crashing issue, game not launching, or black screen while gaming by disabling Weapon Debris and Godrays. Here's how:

Step 1. Open Steam and start Fallout 4 to open its launcher.

Step 2. Go to "OPTIONS" > "Advanced." Then, set both "Godrays Quality" and "Weapon Debris" as Off (best performance).


Step 3. Click "OK" to confirm the changes, and then run Fallout 4.

Some users report the crash is related to fullscreen mode. If the problem remains, try changing the display mode to the borderless window and see if it works. Please share this article with other "survivors" to help them survive longer in the post-apocalyptic world.


Fix 5. Verify Game Files

Steam provides a built-in utility that allows gamers to verify the integrity of game files. If any files are found missing or corrupted, it will automatically restore or replace those files and eventually fix the game crash issue.

Step 1. Open Steam and locate Fallout 4 in your Library.

Step 2. Right-click on Fallout 4 and click on "Properties."

Step 3. In the "Installed Files" tab, select "Verify integrity of game files" to check and repair any corrupt or missing files needed to run the game.


Fix 6. Restore INI Files

Certain file corruption and conflicts with game settings can also lead to Fallout 4 crashing. You can try restoring the related .INI file to its default state to fix the problem.

Step 1. Go to the Fallout 4 directory location. (You may find it in C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 (By default) or C:\Users\username\Documents\My Games\Fallout4.)

Step 2. Locate and select "Fallout4.ini," "Fallout4Custom.ini" and "Fallout4Prefs.ini." Then, delete these files to reset the game settings.


Step 3. Launch Fallout 4, and Steam will replace these files automatically.

This will reset Fallout 4 settings to default and fix any issues with corrupted INI files.

Fix 7. Check If Your SSD Is Corrupted

So I recently got an SSD hard drive now after moving fallout 4 to my new SSD drive the game just crashes on start up..Loads up, 5 seconds into the intro scene and crash, The game was working before on my normal harddrive I do have mods installed but turning them all off didnt fix it so it can't be mods. from Steam Community
