My computer crashes every time I close down Fortnite.

Troubleshooting Persistent Computer Crashes When Closing Fortnite

Experiencing persistent crashes after closing a game can be frustrating, especially if you’re not well-versed in technical troubleshooting. Recently, a user reported that their computer crashes every time they exit Fortnite, displaying a black screen and a specific error message: Kernel Security Check Failure. Initially, the crash manifested as a blue screen, but after installing a Windows update, the error now results in a black screen.

In this article, we’ll explore possible causes for such crashes, outline basic troubleshooting steps, and provide guidance for resolving issues related to game crashes and system stability.

Understanding the Problem

The user observed the following symptoms:

Computer crashes upon closing Fortnite.
Error messages include Kernel Security Check Failure.
Transition from a blue screen to a black screen after a Windows update.
No recent hardware changes or software installations beyond Fortnite and Windows updates.
Limited technical knowledge but willingness to troubleshoot.

While these symptoms can be caused by various factors—such as driver issues, corrupted game files, or system corruption—it’s important to systematically identify potential causes and solutions.

Common Causes and Troubleshooting Steps

Update Graphics Card Drivers

Outdated or corrupted graphics drivers are common culprits for game-related crashes:

Visit the graphics card manufacturer’s website (NVIDIA, AMD, Intel).
Download and install the latest drivers compatible with your hardware.
Restart your computer and test the game.
Verify Game Files

Corrupted game files can cause abnormal behavior:

Use the game launcher or platform (e.g., Epic Games Launcher).
Locate Fortnite in your library.
Select the options to verify or repair game files.
Once the process completes, try closing Fortnite again.
Perform Windows Updates and System Fixes

Since a recent Windows update changed the crash behavior:

Ensure your Windows operating system is fully updated.
Check for pending updates and install them.
Run Windows Troubleshooter for system stability and hardware issues.
Check for Hardware Compatibility and Stability
Run hardware diagnostics to verify RAM, CPU, and storage health.
Use tools like Windows Memory Diagnostic or third-party utilities.
If hardware issues are detected, consider professional repair.
Review Event Viewer Logs
Open Event Viewer (Windows + R, then type eventvwr.msc).
Look under the “Windows Logs” -> “System” for error entries correlated with the crash times
