Why is Call of Duty Warzone crashing on your Gaming Laptop?
There could be many reasons why your games are crashing on your computer. So today, we will go through several ways to help prevent this from happening. I know its not good when you have been smashing Call of Duty Warzone for the last few days, weeks, or even the last couple of years, and then, all of a sudden, the game stops working.
Although, you might be able to start up the Battle.net installer and even go as far as to click play to start running Warzone, and the game loads. But, Warzone won’t stay on screen long enough for your match to start and not even long enough to change your loadout.
Obviously, you have an issue with the programme, and there could be many reasons why this has happened and not just with Warzone.
But when any app or programme stops working, it is because of the changes you have made to your system. Such as updates to your operating system, hardware, or changes to your software.
Another cause could be downloading and installing new software, like new security software, and this can affect programmes and games already on your system.
But don’t worry, whatever the reason for your Call of Duty Warzone crashing, there will always be a way to rectify the problem.
Unless thou you have thrown your computer at the wall after you have been sniped by a Warzone camper. In that case, reading my post will not help you.
And for those who haven’t been throwing their laptops about, read on. I have listed eight ways for you to investigate how to stop Call of Duty Warzone crashing.
Meet the system requirements to stop Call of Duty Warzone crashing?
If you are having trouble running Call of Duty Warzone, the first point of call would be to check if your laptop computer meets the minimum system requirements to run a high fidelity game like COD Warzone.
To check your system spec,
- Press “Windows Key”
- Type “System”
- Press “Enter” on the system information
- Your system information sheet shows your spec
And as long as your laptop spec meets the minimum system requirements for Call of Duty Warzone (see below) then you should be good to go.
If it does, then your spec is not the problem.

How to keep your hardware and system up to date?
When you are experiencing issues with your laptop computer relating to hardware and software, it sometimes can be caused by outdated drivers, or you may have an incorrect driver installed.
Another reason you may be experiencing issues is that your operating system may need updating. It is vitally important to ensure your hardware drivers and your operating system is in tip-top condition.
In return, your laptop will run smoothly, and this will protect your computer from malware and malicious attacks from the millions of sneaky virus’s itching to infiltrate your system.
How to Update Windows 10
Millions of people daily use Windows by Microsoft, and Windows 10 is possibly the best computer OS available. At the same time, not looking after Windows will allow your laptop to become vulnerable.
Here I will go through a few basic tasks to ensure Windows is up to date and to help keep your system running smoothly.
Windows 10 has essential updates, and these should be set to on by default. Essential updates are posted monthly, and they are downloaded and installed automatically. Unless thou, there is an immediate threat to Windows. In that case, the update will be posted as and when.
Also, Windows has optional updates, but these are not automatic. Optional updates are unique to your laptop, or PC and you must check to see if they are required for your hardware.
These include driver updates for your HIDs (human interface devices, mouse, and external keyboards). They also include optional operating system updates and you can check if you need them before installing them.
Sometimes they include only minor, unimportant updates. Therefore, there is no major rush to install them.
How to check for Windows Updates
- Press “Windows Key”
- Start Typing “Updates”
- Select “Check for Updates”
- Click the “Check for Updates” button
Check Windows 10 for Optional Updates
Change Windows Update Timings
You should check your default Windows update settings and change the “Active Hours” to suit your lifestyle. This way, Windows will only update your system outside of the hours you choose.
Doing this will ensure the update process will not affect your work or your gaming. And your system will stay protected without getting in your way.
- Press “Windows Key”
- Start Typing “Updates”
- Select “Check for Updates”
- Click on “Change Active Hours”
Uninstall previous Windows Updates
Maybe, Call of Duty Warzone crashing was caused by updating your operating system with the latest Windows 10 patch. No problem, you can uninstall any previous updates from Microsoft using the uninstall update sheet located on the Windows update page.
- Press “Windows Key”
- Start Typing “Updates”
- Select “Check for Updates”
- Click “Advanced Options”
- Select “View Update History”
- Select “Uninstall Updates”
- Choose the update you want to uninstall
Are your, system drivers, up to date? This could be why Call of Duty Warzone crashes
Device drivers enable your hardware to work correctly with your operating system. You can update drivers manually, using Windows update, or downloading the drivers directly from the vendor’s website.
Microsoft Windows is great for updating drivers for various hardware components including, USB ports, network adaptors, displays, and storage devices.
But, even this can go wrong, meaning you could have an incorrect driver installed. And this can cause issues with your laptop computer.
And this is where the Windows device manager comes into play. Windows “Device Manager” allows you access to the list of hardware you have currently installed.
When using the device manager sheet, you can manually install drivers, update drivers, and uninstall drivers. Also, you can check if your devices are working correctly. And not only that, you can scan for any hardware changes.
Accessing Windows Device Manager
- Click “Windows Key + X”
- Select “Device Manager” from the panel on the left.
- Right Click the Hardware “Select Properties”
The device manager sheet will show you vital details about the driver installed, including the file version. And if the driver is not working correctly, or how it should.
Then you can use the reference numbers to search through support pages for help. Alternatively, you can contact the vendor and give them the exact file number as a reference.
Rolling Back Bad Drivers using Device Manager
The device manager sheet will allow you to roll back your hardware drivers to the previous driver.
- Click “Windows Key + X”
- Select “Device Manager“
- Click the small arrow next to the hardware
- Select “Properties”
- Click “Driver Tab”
- Select “Roll Back Driver”
Installing drivers for third-party hardware: Graphics Card and Processor
Microsoft Windows is great for updating drivers for your HIDs and other hardware listed above. But to update the drivers required for your graphics cards, and processors you would need to visit the vendor’s website.
Or, if you haven’t already done so, you must download and install the update-driver software supplied by the likes of NVIDIA, AMD or INTEL and doing this will make your life a whole lot easier.
As the latest processors and graphics cards on today’s laptops all require some kind of update process for the hardware to work correctly.
This is vitally important to help fix bugs and ensure you have the latest performance enhancements, and, on occasion, you will be treated to the latest features.
Are your NVIDIA Graphics Card Drivers Updated?
If you are one of the lucky ones and have an NVIDIA graphics card for gaming, then you should already have GeForce Experience downloaded and installed on your gaming laptop.
If not, this should be your priority. Click here: Download GeForce.
On the same page, as you download GeForce, you can search for the latest drivers, and you can double-check the drivers against what you already have.
Using the NVIDIA GeForce experience will allow you to re-install drivers and set your in-game overlay settings to meet your needs. Not only that, but you can also record live gameplay and share it with your friends, or even your enemies if you wish, across social media.
After downloading the software and setting up your profile, make sure you have “Automatically Download Driver Updates” ticked, and you will find this option at the bottom of the general page.
Doing this will ensure your graphics card drivers are kept up to date and without you having to worry as often. But there will be the odd time you need to manually check and make sure your drivers are the latest available.
Are your AMD Drivers Updated?
AMD, like NVIDIA, offers superb device driver and utility software to help support your GPU’s and CPU’s. And without these tools, your life would be much more difficult.
AMD’s Radeon software will help keep your graphics and processor units updated. If you haven’t already, you need to download the combined AMD chipset and Radeon Graphics driver installer.
The Radeon auto-detect tool will note which chipset, graphics card, and version of Windows you have installed and then provide you with the latest drivers compatible with your system.
Download Here: AMD Radeon Software
Best Radeon settings to enable
After you have downloaded the Radeon software, make sure the “check for updates” tab is set to automatic, and the “Download Drivers and Software” is enabled.
You will find these settings on the “System” tab.
And to ensure you have the latest drivers you can select “Check for Updates”.
Are your Intel drivers updated?
Intel offers the driver and assistant auto-detect tool. This tool will update most of Intel’s products, but it won’t work with all. Although if you have an Intel CPU, you must have this tool running on your laptop computer.
The Intel auto-detect tool will continuously scan your PC for driver and software updates and provide you with vitally important system and device information.

How to check if your game is up to date?
Call of Duty Warzone crashing could be happening because your current version of the Warzone is not up to date. Or there may be an error in one of the game files, and either of these reasons could cause Warzone to crash.
Although, like most decent game installers, Battle.net does comes with several handy features to help make your games run smoothly on your gaming laptop.
And for Call of Duty Warzone to work correctly or any other game you play linked to the battle.net platform, you must ensure your game files are up to date.
Battle.net makes it easy for you to check for updates manually. And you can scan and repair the game version you have installed to ensure you don’t have corrupt files lurking around.
Updating Games Using Battle.net
To update your game installed through Battle.net, select the wheel next to the “Play Button” on the Battle.net home screen. Then select “Check for Updates”, it will only take a second or two to check to see if you have the latest updates for your game.
Once the check is complete, restart the game. If it doesn’t work, then you are not having much luck. Next, try “Scan and Repair”.
There is also an option to uninstall the game or modify the install, but those options are the last resort. And especially knowing how long it takes to download and install Call of Duty Warzone.
Besides, if COD Warzone has previously worked on your machine, then there should be no reason why you cannot rectify the issues before jumping onto uninstalling the game.
I’m sure you don’t want to be wasting the best part of two days waiting for COD Warzone to install.
Therefore, if you haven’t managed to fix Call of Duty Warzone crashing, read on.
Does your system have enough RAM to stop Call of Duty Warzone from Crashing?
A common reason why a game fails to load is that your system does not have the required RAM to handle any more programmes, or you have too many applications running simultaneously.
Hey, if you are anything like me, I have my email client, browser with seven or eight pages open, and depending on the tasks I am doing on the day. I may have Adobe Photoshop running or Adobe Rush.
As you could imagine, my laptop’s CPU and RAM sometimes takes a beating.
That said, when I do decide to put my work away and turn into a passionate gamer, I ensure the apps and programmes I do not need are closed down.
Therefore, I would recommend that you close any app or programme you don’t need when you decide to jump into Warzone. And only have the Battle.net installer and your system vitals software running, if possible.
Did you know, when you close apps and programmes using the X-Button at the top of each sheet, Windows may not shut them completely? So they could still be running in the background, therefore, taking up precious RAM and processing power.
You can close programmes and apps completely using the Windows Task Manager sheet.
Free up memory using Task Manager
- Click the Windows Key + X
- Select task manager
- Right-Click a programme to end the task
Check how much RAM your system has available
Many different hardware components can affect the performance of your laptop. Like your graphics card and your hard drive, both can be the cause of poor performance.
However, two of the most important components that will affect your laptops performance are the processor and RAM (memory).
The great thing about RAM, especially for laptop computers, is you can upgrade the RAM to improve performance, and your gaming will benefit from additional memory. Adding more RAM is possibly one of the cheapest upgrades you can do with the most benefit.
Unfortunately, the same cannot be said for the processor, which is much more difficult to upgrade, if at all.
If you are unsure how much RAM you have available on your laptop computer, you can check the system info. To bring up the system info sheet, follow these steps.
- Click the “Windows Key”
- Type “System Information”
- Click “Enter”
Windows System Info Sheet
Having enough RAM to run your games, operating system, system vitals software, and in this case, the Battle.net installer is vitally-important to ensure your laptop runs smoothly.
Call of Duty Warzone crashing could be because you don’t have enough RAM to handle the game.
Warzone, in particular, requires you to have a minimum of 8 GB RAM to allow the game to run on your device. And 16 GB would be the sweet spot, my gaming laptop has 16 GB RAM, and Warzone runs like a dream, plus other apps and programmes.
So, after you have checked your RAM and you see you have less than 8 GB RAM. Then you will need to add more. Or if you only have 8 GB RAM, close all programmes and apps, apart from Warzone and Battle.net and try again.
If it still doesn’t work, then you may need to install additional RAM to stop Call of Duty Warzone crashing.
However, if you find you have more than enough RAM and Warzone will not run. Then, continue reading, hopefully, you will find a solution.
Does your system have enough storage space?
The latest gaming laptops now come with SSDs as the storage solution, and they are smaller and faster than ever before. My current gaming machine only has SSD storage, so no bulky hard drive slowing down my day or my laptop.
But still, I regularly clean up my footprint every other day and delete what I don’t need as and when I can. If I didn’t I know my laptops performance will suffer. And my programmes and apps may not work how they should.
So, it’s vitally important you keep on top of your storage and remove unnecessary information from your laptop, and when you only have an SSD, this is especially important.
Deleting your photos and folders from your laptop should be done daily. Although. you can manually delete these, but sometimes dregs are left behind, files you don’t see on your desktop, or when searching through your documents.
To locate them, you either need to search through your documents, many folders, and hidden corners or you can make your life easier and download a decent and possibly free system clean up programme.
And there are some fantastic free computer cleaner programmes you can use to help you remove unwanted files from your laptop computer.
I use Total AV antivirus software and they have a free version and a paid pro version. But the free version is adequate for what you will need.
Unless you want the full bells and whistles, then go for the pro version.
How to find Windows 10 Disk Clean-up sheet
Windows offers a decent tool to help remove files from your storage space. The disk clean up tool will go some way to help you remove the unnecessary file from your laptop.
Other ways to improve your storage space
There are other ways you can improve your storage. Windows OneDrive is great, and it only takes a second or two to set up and away you go.
OneDrive will help you free up more space on your gaming laptop by transferring files, photos, and folders you want to keep but don’t necessarily need every day over to the cloud storage.
There are others like Dropbox, Google Drive, or Apple iCloud, and they all offer various amounts of free storage, and after you have reached your limit, they have varying prices for additional storage.
For the record, I am not to keen on Dropbox, I have used it before, and I felt it took a long time and loads of effort to update files and folders from my device to the cloud storage. However, I have used OneDrive for many years, and I have yet to pay for additional storage, also, it is easy to use.
Alternatively, you can invest in additional storage and swap out your SSD for a bigger one, or you can purchase an external storage device that you can connect to your laptop via the USB port.
In an ideal world, you want to have two storage options. One storage option for storing and booting your operating system. And the 2nd drive to use for your games and large files.
Have you created multiple hard drives or partitions?
Installing and uninstalling software from your laptop computer can affect your system files. If not done correctly and especially security and monitoring software, this could have dire consequences for your laptops performance.
An example, when you try to run a game like Call of Duty Warzone using the Battle.net installer and you are getting the error message ‘could not write file hard drive full’.
Quite possibly, you may have accidentally created a partition within your hard drive. And this could have happened when you have uninstalled or installed new software.
And even if your laptop does not have a hard drive, you could still get this message. Annoying, I know.
If you are experiencing this error, what is happening is Warzone is trying to load onto a partition you have created. And the hard drive does not have the required space, or it may not have any space at all, or you could only have an SSD.
How do I know? Because this happened to me, and I was able to correct it?
So if this is happening to you, follow these steps below. Hopefully, doing this will rectify the problem and Call of Duty crashing won’t be an issue you need to deal with anymore.
Clear Battle.net Programme data folder
- Press the “Windows Key + R”
- In the run box type %ProgramData% then click “OK”
- Find and delete the Battle.net folder
Clear Battle.net App data
- Press the “Windows Key + R”
- In the run box type %AppData% then click “OK”
- Find the “Battle.net folder” inside the Roaming folder and delete
- Select “AppData” on the top bar.
- Select “Local Folder” then select “Battle.net” folder
- Clear the “Logs Folder” and “Cache Folder” inside the “Battle.net folder”
Run Battle.net application
- Locate the Battle.net folder inside your “C Drive”. (Not the shortcut)
- “Right Click” and select “Run as Administrator”
- Battle.net installer will load, then try loading Warzone
- You will have to re-enter your credentials
Hopefully, you have rectified any issues you are having with the Call of Duty Warzone crashing.
Although, if you are still experiencing issues with loading Warzone. You could either try the steps above again. But, before you run the Battle.net application, re-boot your laptop.
However, if you are now at a stage where you are pulling out your hair because you have tried the steps above, and they have failed to get your game running.
Unfortunately, the only alternative would be to uninstall/reinstall the game or application. But before you jump the gun and uninstall Warzone read on as you may still find a fix.
How to check if Malware is affecting your gaming?
Malware, short for malicious software, can be an absolute nightmare for your laptop computer and can slow down your PC. More importantly, malware can be the culprit who steals your secrets and access your information, and if you are not careful, you could lose everything.
The worst thing about malware is it can come in many forms, Virus’s, Trojan horses, Rootkit, Spyware, and Adware. These are just a few of many forms of malware that can infiltrate your operating system.
Most of the time, you have unknowingly accepted these tiny pests onto your system. And that could be in the form of a toolbar add-on or browser extension, or maybe you have opened an email.
You can also get malware from inserting a flash drive or USB into your laptop computer, so watch out for that as it does happen.
Yes, and I agree, this all sounds a little crazy, but malware can and will affect your programmes and could be the reason Call of Duty is crashing.
But there are many things you can do to prevent yourself from being a victim and help keep your system safe so you can enjoy your gaming stress-free.
Use Microsoft Safety Scanner to check for malware
One of the reason why your games are crashing or your laptop is not running how it should is because you have invited malware or a type of virus onto your system.
Yes, you could have prevented this, but sometimes you may not even realise how it happened until it is too late. However, you can check your operating system for malware by downloading and running the Microsoft Safety Scanner.
The Microsoft Safety Scanner is a free tool that will scan your Windows laptop computer looking for malware. You can download it for free from Microsoft’s website, and it only takes a couple of minutes to install and run and you will get your results in minutes, if not seconds.
Download and Run: Microsoft Safety Scanner

Use a third-party anti-malware program with Windows 10
Although Windows 10 will provide real-time protection and will periodically scan your drives for malware. It is also a good idea to install a third-party anti-malware scanner.
Installing an anti-malware scanner that will coexist with Windows Defender will give you extra protection against the many forms of malware and virus that lurk around.
My personal favourite and the one I use daily is Norton anti-virus software, and of course, there are many other alternatives that all promise to keep your system safe.
But I found Norton easy to install and use, and since downloading the programme several weeks ago, I have had zero issues with malware. Also, I can scan my laptop daily, remove tracking cookies, and delete unseen files taking up my storage with a click of a button.
Norton software is great, especially with the kind of work I do and the number of files, videos, and images I create daily. Ok, there are many other software providers you can use, but I will only recommend what I use.
The Norton anti-virus software is free to download, and once you are happy you can purchase a subscription for very little money. It comes complete with everything you need to help keep your laptop computer safe.
Including, Anti-Spyware, Anti-Malware, Anti-Ransomware, Anti-Adware, Real-time protection, Remote firewall and will be compatible across all your devices.
Norton Anti Malware Software
How to stop Windows Defender/Firewall from blocking your game
Another reason why your games or programmes are not working how they should, is that the Windows Firewall if blocking them from running.
Windows 10 has a superb built-in anti-malware software called Windows Defender and Windows firewall and offers real-time scan based anti-malware protection against anything your download and run on your laptop computer.
At the same time, Windows Defender can also prevent your games from loading if you have dodgy or corrupt files within the latest update.
But you can manually allow your applications or programmes through the firewall.
Follow the steps below to add Call of Duty Warzone or any programme or application through the Windows Firewall you may be having issues with.
- Press “Windows Key” start typing “Windows Defender Firewall”
- Press “Enter” when you see “Windows Defender Firewall”
- Select “Allow an App or Feature”
- Then click “Change Settings”
- Finally, click “Allow another App”
- Click “Browse” to search for your application
- Locate the Game Application folder, C: drive/Programme Files/Your Game
- Click Open to add, then click the “Add Button”
How to uninstall games and applications form your gaming laptop?
Ok, we have now come to the last stand, and, you have tried all the possibilities above and still, you have no joy.
Therefore, if Call of Duty Warzone crashing is getting too much, then the last resort would be to uninstall COD Warzone, including the Battle.net platform and go through the painstaking task to reinstall everything again.
By uninstalling COD Warzone and the Battle.net platform you are removing all the files associated with the game, and this includes all the references to any of the files in the Windows registry.
The registry is the master database of Microsoft software and hardware settings.
Furthermore, when you reinstall the game and the battle.net installer, all of the Call of Duty Warzone files and settings are restored in the correct locations.
Not only that, but also within the Windows registry. Simply put, you are starting with a clean slate.
There are several ways to uninstall your games and your programmes. But, not every way will remove all the necessary files and folders.
Therefore, follow the steps below to uninstall Call of Duty Warzone and the battle.net platform the right way and the best way.
After uninstalling your game, it is always a good idea to ensure there are no files left lurking behind and searching for and removing these will ensure you get a clean reinstall.
Check the following folders for any files relating to your game.
- Find: C:\Program Files\CallofDutyModernWarfare
- C:\Program Files (x86)\CallofDutyModernWarfare
- C:\Program Files\Common Files\Blizzard Entertainment
- C:\Users\Public\Public Documents\Blizzard Entertainment\CallofDutyModernWarfare\
- C:\Documents and Settings\Local Settings\Temp
How to uninstall the Blizzard Application
Now that you have uninstalled Call of Duty Warzone, it would be best to uninstall the Battle.net application. That way, when you install COD Warzone and the Battle.net application, you will have new files and folders located in the correct order. And in the right position.
Because if you were to only uninstall Warzone, and, then wait the eight hours for the game to re-install. Only to find that you still have issues with Call of Duty Warzone crashing.
Quite possibly you would have to uninstall the game all over again. So not good.
For your information, you won’t lose any of your settings, or profiles by uninstalling Battle.net.
Once you have downloaded and installed Battle.net you can log back in with your credentials, and you will be good to go.
- Open “Control panel”
