If you got some problems running Fallout 4, then you are not alone and it was a really frustrating way where it can run smoothly with no major SPX drops and without crashing to the desktop every five minutes.


Method 1 to fix Fallout 4 crashing on start-up

Step 1 to fix Fallout 4 crashing on start-up

This works for the parted and steam version. The first step you want to do is right-click fallout and click on properties, go to local files if it is a fresh install do not worry about this, if it is not a fresh install go ahead and verify. This could take a little time and the next step after that is to browse local files, if you have the pirated version simply just find where you installed the game and open the folder, both for fallout 4 and fallout 4 launcher, you are going to want to right-click run this program in compatibility mode for Windows 7 as well as admin and do the same, all right once that is done you go ahead and exit this out because unlike other tutorials that tell you to edit some of these files and go through the settings does not really help.

The second step would be clicking play or fallout 4, now that you are in options you going to go ahead and do the next steps. Before you do this you need to update your CPU and GPU drivers.

Step 3 to fix Fallout 4 crashing on start-up

Here are a few steps you can follow to update CPU and GPU:

Go to Google, type whatever brand GPU or CPU you have and then type the word drivers download after that open their actual page not any third-party pages and there should be an automatic browser tool that will literally search your computer from the browser and find the most updated driver so once you have done that and restart your computer.

Go back to the launcher and hit options.

Step 4 to fix Fallout 4 crashing on start-up

The next best step is to just simply tone down the settings, you can check every single setting, and view distance does absolutely nothing for the crash, these settings here are absolutely perfect for crashes and that also includes unchecking motion blur. Now if you have lower-end products that are even lowered than the GTX 260 or lower than the i5 4690K, you can go ahead and just put low on all these and off for these as well.

You can also put your filtering to four samples the anti-aliasing to fxaa, putting it in Window mode or borderless mode like people say does not really do anything. There have not been any increases or decreases in crashes or anything like that.

Step 5 to fix Fallout 4 crashing on start-up

The final step is to download and install MSI afterburner, this tool is basically a GPU overclocking tool but that is not for what we are going to be using it for, we are actually going to be using it to set the fan speed.

Once this is open you are going to look at fan speed, make sure this is on auto, and hit the little settings next to it and the fan, make sure that this is checked and you will look at a graph, so the bottom is the temperature in Celsius and the fan speed from zero to hundred in the graph. Leave everything here alone and just worry about this so when this reaches exactly 80 degrees Celsius is when the game just randomly crashes, there is no crash log that comes up or nothing.

Step 6 to fix Fallout 4 crashing on start-up

It just goes straight to the desktop so to prevent your GPU from reaching that temperature, you are going to move the dot in the graph and look for the highlighted number below 475, make sure it matches up with 100, and now what this will do is when your GPU reaches this temperature, it changes the fan speed to hundred and you also have eighty Celsius there to a hundred as well but this really does not matter because when it reaches 80 is actually when it crashes so that is why seventy-five Celsius is set to hundred and also make sure not to open this tool randomly, just have it open only when you are playing this game or any other game that seems to crash like this.

Step 7 to fix Fallout 4 crashing on start-up

Once that is done you can hit apply, now go to monitoring, GPU temperature left click that and then click Show in the on-screen display, go to on-screen display and you set this to whatever hotkey you want, for example, num lock the actual button for the toggle. The show on is set to the slash on the num lock and the height is to hide the on-screen display set to the Astro key so once those are set, hit apply and ok.

Now when you open the game, simply press the num lock key and then press or actually whatever hotkey you have and then press the hotkey to actually toggle it, and now you can see your temperature at the top left, and then you will know if you are getting close to 80, so you can go ahead and save your game and it will prevent you some headache for whatever it crashes so hopefully it helped.


Method 2 to fix Fallout 4 crashing on start-up

If you have got a slightly dated PC or laptop but you are trying to hold it together for as long as you can so you play all these next-gen games and perhaps you do not have what is required, you might be experiencing this problem when you start fallout for the first time and you get it all – detected everything you can see that it sets it for low quality.

You try this again all, you are ready to get going, you press play and what happens is that it tries to load a bit of a problem so it tries to load again and then you get the black screen.

First of all, do not worry, it is totally fixable, if this is the first time you have ever actually downloaded a game from steam or you have enjoyed a PC game, this is all part and parcel of the fun, imagine this is just a little mini-game before you get to play the game and it is all about changing code which is like there are exciting things.

Some of you might be able to get away with this if you just select Windowed mode and borderless windows so it will be like this little pop-out here but without the blue section. You might be able to get the right resolution for the size of your screen and if that is the case then when you press play it will work which is good but the problem is as you can observe here, it is in a sort of awful tucked away in the top right-hand corner.

It’s not got the right resolution for you, you could probably get away with it but you know what it’s going to be as immersive going to work every morning and that is unenjoyable. Let’s do something different, first change some files here is the main file that you are going to need to change, it is any file, it is a preference file.

Do not worry we are not altering the game and not changing crazy lines of code, we are literally just telling the game hey this is how I like to play. So what you need to do first of all is go to documents, go to my games and fallout 4, now you should then be presented with these files, this is the one that you have to change and as you will see loads of stuff very confusing what does it all mean, well it is just very simple language computer that understands if you want to do a quick control F and find something that we are looking for is being maximized window, so you can find that nice and easy and these are the things that you are going to edit.

So what you need to do first of all is have the maximized window zero be borderless equals one be fullscreen equals zero and then you are going to go down here, just to make it nice and easy, we are going to make it fault-proof. We are going to say to the computer, do not worry about trying to make this full screen yourself, these are the dimensions that we have so, for example, the height is 10” 20’ and the width is 10” 80’ and the width is 9”22’, so change that to whatever sort of suits you guys as well you can find out your own resolutions and then all you need to do is save.

Before you make any changes to this, it is always wise to just cut or copy and paste this somewhere else is just like a default file. Now if you want to make this super tight and really do this properly, you do not really have to do this in truth but sometimes it is nice to just do it in all places if you navigate through to steam, steam apps common and then fallout 4, you will see that you can see some other files here as well, you have to double click into the fallout 4 again to find that prefs in it, so your link is going look something like this indeed if you have downloaded it from steam.

Again just open this up, navigate down to these sides and change these things to be maximized window 0, so on so forth down to the right sizes, save again.


Now when you play this, you will see that you have tricked fallout 4 into working on your computer. So do not worry about anything and you can enjoy playing Fallout 4.
