This article explains ways to fix the Fallout Crash on Startup. But first, let’s see why the Fallout is crashing on StartUp.

Why is Fallout 4 crashing on startup?

This problem is common, especially for people who are playing on PC. Fallout 4 has a lot of issues running on PCs with Windows 10 due to the fact it wasn’t truly optimized “to make use of all of your system’s hardware / software” when it was released.

For example, if you have an NVIDIA Geforce GPU, you are likely experiencing crashes more often than not. Fallout 4 was coded mainly with AMD in mind, and NVIDIA cards are known for their lackluster performance with Fallout 4 compared to their AMD counterparts.

Any game could crash randomly while being played, but most have some sort of solution. For example: If this issue happens suddenly during gameplay, change the resolution to 720p windowed, exit the game, and change the file Fallout4Prefs.ini located in C:\Users\USERNAME\Documents\my games\Fallout4 open the file with notepad or any text editor replace “bFull Screen=1” with “bFull Screen=0” save changes.

Method 2: Fallout 4 Crash Fix – Mod Conflict Detector

If your game is crashing after installing a mod, you should use a Mod Conflict Detector program to scan your computer for any conflicts between mods or save files that may be causing a crash in Fallout 4.

How else can you Fix Fallout 4 Crashing with the Mod conflict detector?

Follow the steps below to fix your Fallout 4 from crashing:

1) Run a system file check to repair corrupted system files, and then restart your computer to apply changes.

2) Update all of your device drivers manually by going to the manufacturer’s website for each one and downloading the latest correct driver for your operating system.

3) Uninstall all non-Microsoft programs except for antivirus, audio/video players, or other essentials before you run Fallout 4 so that there will be no conflicts with how those programs access you. If you have recently added new hardware to your computer, uninstall it and see if that solves the problem. If you have newly installed a pirated version of Fallout 4 without un-checking the ‘crack’ box, this is likely causing your problems. You can either install or re-download the game legally and ensure all components are checked.

4) . Bethesda has created an easy utility for finding and removing mods that may be causing issues in Fallout 4, called the Fallout 4 Creation Kit.

5) Check that your PC’s BIOS is up to date, and update if necessary; it will need to be compatible with the game. You can check the official Bethesda website for more information about your motherboard’s compatibility. 6) If you are still experiencing problems after following all of these steps, re-install Fallout 4.

Method 4: Disable Mods

– If your game is still crashing after completing the above steps, try disabling mods in Fallout 4 to see if it fixes the crashes. You can disable all mods in Fallout 4 by right-clicking on the game, selecting Properties, and clicking on the Beta tab. Select ‘None’ from the drop-down menu and click Close.

So, you’ve tried to install Fallout 4, and for some reason, it keeps crashing on startup. You might remember seeing a blue screen with an error code that looked something like this:

0x0000006b 0xc0000005 0xf78bb8e3 0xf78bb890

That’s an error code that threw up after trying to boot up Fallout 4. The first thing I would recommend checking is the system requirements for the game since its release. Bethesda has been known to be shoddy in testing games before they go live, so perhaps your machine doesn’t meet the minimum specs required. If your system does meet or surpass these settings, then we can proceed further:

Method 5: Run, Verify and Install any updates through Steam.

You should run Fallout 4 fine, but if it crashes frequently or has other issues, you might not resolve the problem yet.

Disable all third-party applications that can interfere with game performance. You should disable anything that isn’t required for your system to run smoothly while gaming. Anything from overclocking software to background programs like Dropbox, Avast AntiVirus, and Skype could be causing this issue.

Method 6: Uninstall / Reinstall Fallout 4 via Steam 

If updating doesn’t work, try reinstalling Fallout 4 on your computer by doing the following: Open up Steam Right-click on Fallout 4 in your Library Select “Delete Local Content” This will only delete the files for Fallout 4 in your Boot drive – do not delete any other Steam games you have installed as this will mess up your Steam Library. Once the files are deleted, open up your Steam software and re-install Fallout 4 (you should also redownload any DLC content if you own any).

If reinstalling didn’t work for you, then we need to proceed to the next step:

Method 7: Reinstall DirectX and VCRedist.

The last thing we can try before throwing in the towel is doing a clean installation of both Visual C++ 2013 Redistributable Packages for Visual Studio 2013 and DirectX. If you’re not sure how to do this, then check out our guide that teaches you just that right here. Note: You don’t have to install those programs – just reinstall them from the installer files.

Method 8: Clear Fallout4Prefs.ini and Fallout4.ini

The last thing I would try before reinstalling the game is to clear out your ini files by doing the following: Go to C:\Users\%USERNAME%\Documents\My Games\Fallout4 Delete Fallout4Prefs.ini (and all other ini files that are located in this folder).

Open up Steam Right-click on Fallout 4 in your Library Select “Properties” Click “Verify Integrity of Game Cache” Once it’s done, re-open Fallout 4 and see if it works fine now!

How to Troubleshoot Fallout 4 Crash on Startup

The following list consists of various possible solutions that may resolve your crashing issue when attempting to start the game:

1) Verify Integrity Of Game Cache

As mentioned in our article on how to fix Fallout 4 startup crash after update, verifying the integrity of the game cache will ensure all the files are present and up to date, allowing the game to make sure all files are there and none are corrupted. Navigate to Steam -> Library -> right-click on Fallout 4 -> click Properties -> Local Files tab -> click “Verify Integrity Of Game Cache”

2) Update Graphics Driver (Nvidia/AMD)

If you’re using an AMD graphics card, updating your drivers can be beneficial. For Nvidia cards, updating the driver is unnecessary as older drivers tend to work better with Bethesda titles anyway.

3) Disable SLI/Crossfire

To disable multi-GPU options in Fallout 4, navigate to your Fallout4Prefs.ini located in C:\Users\%USERNAME%\Documents\My Games\Fallout4. Open it up with notepad and change “bForceIgnoreSm3=0” to “bForceIgnoreSm3=1”. Save & exit.

4) Overclock GPU (if overclocking software available)

(shouldn’t be necessary if you followed the previous step) If your GPU supports this, this can resolve any crashing issues when trying to load textures on some cards. To do so: Open up MSI Afterburner Navigate to Settings -> General Uncheck all options besides monitoring for this option Set core clock offset -100 or just under that And then increase Power Limit by 10% or however much your card allows

5) Update drivers for motherboard/sound card / other add-on cards Your motherboard, sound card, and any other add-on cards might use their software or drivers, which you need to check for possible updates.

6) Disable game mods (Fallout4Prefs.ini location is as per step.

7) If you’re running any game modifications (from Nexus, Workshop, etc.), then try disabling them and see if that helps with the startup crash. You can always re-enable them later after you play the game successfully once without them!

8) Verify integrity of game filesSteam users: Go to Steam -> Library -> Right-click on Fallout 4 -> Properties -> Local Files tab -> “Verify Integrity Of Game Cache” option Non-Steam users: Make sure Fallout 4 has been completely closed down before proceeding. Go to C:\Program Files (x86)\Steam\steamapps\common Delete everything except the games folders Re-install Fallout 4 If the game still crashes; it means something is wrong with your installation, and you’ll need to re-install it completely.

9) Disable/Enable Custom ini tweaks This applies only if you have changed your .ini files. Navigate to C:\Users\%USERNAME%\Documents\My Games \Fallout4 (the path will vary if installed elsewhere or on another drive) Open Fallout4Prefs.ini file Change bUseTextureStreaming=1 to =0 Save & exit Try starting the game once again, see if it helps. If not, change this value back to 1.

10) Disable/Re-enable Fallout 4 Steam Cloud Save Sync (applies only if using the cloud to store save files)

11) Delete PCHealth folder and Re-install Windows 7 Services Pack 1 + Hotfixes (applies only if you’re running Windows 10 and experiencing this issue, other OS not tested.) Ensure you’ve closed down Fallout 4 before proceeding. Go to C:\Windows\System32\dllcache Delete PCHealth folder Navigate to C:\Windows\System32\dllcache again Rename Shim’s folder to Shims.old Download a fresh copy of the Shims from here: 

http://www.greyhoundgames.com/games/files/shiminstances/shatspace.7z Unzip & copy all files from the downloaded folder to C:\Windows\System32\dllcache Start Fallout 4 and see if it crashes.

 If not, you’re done! If it still crashes, rename the Shims folder back to Shim’s and try the next step. Re-install Service Pack 1 + Hotfixes for your OS either via DVD or online and get Windows Updates for offline install.

12) Update Display Driver (Nvidia/AMD)   If this was any other game, updating the graphics driver probably wouldn’t help. Still, according to reports on Reddit, users who updated their drivers were able to get rid of Fallout 4 startup crashes!

13) Fallout 4 Configuration Tool: Set everything as low as possible.

14) Verify game files: Go to Steam -> Library -> Right-click on Fallout 4 -> Properties -> Local Files Tab -> “Verify Integrity Of Game Cache” option

15) Low Ram Make sure you have enough RAM (memory) available when running the game. If the game uses too much memory on your computer, it can crash when trying to play it. Have at least 6 GB of free system memory available when playing the game or more if you’re planning to use mods or install HD texture packs!

16) Low VRAM Check details about your GPU and ensure you don’t have too little VRAM (video memory). The game might not be able to find enough video memory and crash. Ensure you have at least 1 GB of video memory available on your GPU!

17) Run the game in Windowed Mode – No Border

18) Run the game with graphics settings set to Low. Set everything to Low, not just some options. This is very important if you’re trying to run the game on a laptop or an older PC that can barely handle it without crashing.

You might also want to turn off FXAA since it’s heavy on performance. If you are using FRAPS for benchmarking/graphing performance, disable these features under Tracking before launching Fallout 4: Object Buffer Shadows, Dynamic Spot Shadows, Directional Occlusion.

Why Does Fallout 4 Keep Crashing?

Don’t worry if you ever find yourself playing Fallout 4 and suddenly feel like the game has stopped working. It’s not broken. Fallout 4 is crashing – it’s just doing so in a specific way that results in what looks like a crash but isn’t, for lack of better phrasing.

Here are the reasons why Fallout 4 crashes on startup:

*You’re using an outdated version of Windows 10 or haven’t updated your GPU/CPU drivers to their latest versions yet.*

*Fallout 4 needs DirectX 11 to run, which you might not have installed yet even though it comes with Windows 10 (which is usually the case).

*You have too many Fallout 4 .esm files installed. You can check by right-clicking the game in the Steam launcher, clicking “Properties,” and going to the “Local Files” tab.

*You’re using third-party mods that aren’t compatible with each other or haven’t been cleaned for Fallout 4 yet. If you’re sure none of your mods are causing this issue, try deleting them one by one until you find the conflicting mod(s).

*The mod manager you’re using might be causing a conflict with another mod tool. If possible, try switching to a different program or upgrading to the latest version of your current program if it’s not already on its latest version. [Note: In most cases, NMM is the best choice.]

*Your game directory might be corrupted. Try reinstalling Fallout 4 or switching to a different game directory.

*You have an antivirus program that’s blocking Fallout 4 from running, so you’ll need to turn it off at least temporarily while playing Fallout 4.
