It’s recommended that you check if your gaming rig satisfies the Warzone’s minimum system requirements before diving into the fixes below.

Fix 1 – Install the latest game patch

You may encounter a lot of unexpected bugs or issues when playing relatively new games, but thankfully developers will regularly release new patches to fix them. So if Warzone is constantly crashing your PC, go check for the available update, install it and see if that solves your issue.

If not, let’s dig deeper into other causes related to your graphics driver, running programs, game files or the virtual memory setting.

Fix 2 – Update the graphics driver

A range of gaming problems such as crashes or freezing can be caused by a wrong, faulty or outdated graphics driver. Call of Duty Warzone is no exception. To play it smoothly, you’ll need to keep your graphics driver up to date.

You can get the latest graphics driver from your graphics card’s manufacturer such as AMD or NVIDIA, and manually install it. If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the flagged graphics card driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)

You can do it for free if you like, but it’s partly manual.
The Pro version of Driver Easy comes with full technical

Now test if the new graphics driver renders Warzone in stable and enhanced performance. If the crashes still don’t stop, there’re more fixes to try.

Fix 3 – Verify the integrity of your game files

Missing or damaged game file is another known culprit of Warzone crashing on PC. But don’t worry, resolving this problem is as simple as making a few clicks.

1) Launch the client.

2) Click Call of Duty: MW in the left pane. Then, click Options and select Scan and Repair from the drop-down menu.

3) Click Begin Scan.

Relaunch Warzone after the process finishes, and see if everything goes back to normal. If it game continues to crash, head to the next fix below.

Fix 4 – Close unnecessary background applications

Background applications that conflict with CoD Warzone or drain much system resources can also trigger the crashing issue. So, to better enjoy the game, you’re suggested to shut down unnecessary applications. Here’s how:

1) Right-click on any empty place in the taskbar and click Task Manager.

2) Right click the application you want to close and click End task.

Don’t end any programs you’re unfamiliar with, as they may be critical for the functioning of your computer.

Closing everything else in the background is supposed to make CoD Warzone run normally. If the crash is still there, check out Fix 5 below.

Fix 5 – Increase virtual memory

When your computer gets low on memory, virtual memory serves as additional RAM. But if it’s not sufficient to handle some resource-demanding applications you’re running, such as CoD Warzone, the crashing issue will occur. To see if this is the case, you can extend the virtual memory via the following steps.

1) Click the Start button and type advanced system settings in the search bar. Then, click View advanced system settings.

2) Click Settings under the Performance section.

3) Select the Advanced tab. Then, click Change.

4) Uncheck Automatically manage paging file size for all drives.

5) Select the C drive. Then, click the box next to Custom size.

6) Enter the initial size and maximum size depending on the amount of RAM your PC has. Then, click OK.

Microsoft recommends you set virtual memory to be no less than 1.5 times and no more than 3 times the amount of RAM on your computer.

After you complete the steps above, test if Warzone works well. If, the same crashing issue comes back, proceed to next fix below.

Fix 6 – Temporarily disable Windows Defender

Windows Defender aims to protect your computer from threats or hazards, but it may block some of your applications by mistake and stop them from operating properly. You could temporarily disable Windows Defender and see if this allows you to play CoD Warzone as usual.

If you’re on Windows 10

If you’re on Windows 7

Windows 10

1) On your keyboard, press the Windows logo key and I at the same time to enter the Windows settings menu.

2) Click Update & Security.

3) Select Windows Security in the left pane, and click Virus & threat protection.

4) In the pop-up window, click Manage settings.

5) Toggle off Real-time protection.

Restart your computer and launch Warzone to test this method. If Windows Defender isn’t the reason to blame, move on to Fix 7 then.

Windows 7

1) On your keyboard, press the Windows logo key and R at the same time to invoke the Run box. Then, type control in the field and click OK.

2) Select Small icons under View by, and click Windows Defender.

3) Click Tools. Then, click Options.

4) Select Administrator in the left pane, and untick the box next to Use this program.

5) Click Save.

Restart your computer and launch Warzone to see if it works flawlessly. If you still run into crashing after applying this workaround, try the next fix below.

Fix 7 – Disable Overlay

The overlay feature is reported to be a potential cause of your CoD Warzone crashing problem, and it’s suggested you turn it off during the gameplay. Below we’ll specifically show you how to do this on Discord and GeForce Experience.

On Discord

1) Run Discord.

2) Click the cogwheel icon at the bottom of the left pane.

3) Select the Overlay tab in the left pane and toggle off Enable in-game overlay.

On GeForce Experience

1) Run GeForce Experience.

2) Click the cogwheel icon at the upper right corner.

3) Toggle off In-game overlay.

If disabling the overlay fails to fix the Warzone crashing neither, you can attempt the last fix.

Fix 8 – Rename the game file

If all else above don’t help, try renaming the game file. Although this method seems a bit odd, it works like a charm for many players stuck in the endless crashes.

1) Launch the client.

2) Click Call of Duty: MW in the left pane. Then, click Options and click Show In Explorer.

3) Open the Call of Duty Modern Warfare folder.

4) Double-click the ModernWarfare.exe file and rename it as ModernWarfare.exe1.

Open Warzone and see whether you can enjoy it without interruptions now.
