How to Fix KERNEL_SECURITY_CHECK_FAILURE Error in Windows 10 & 11 (Step-by-Step Guide)

Encountering the KERNEL_SECURITY_CHECK_FAILURE Blue Screen of Death indicates that a wide variety of potential issues, such as incompatible drivers, corrupted system files, or faulty RAM, have compromised the operating system's core kernel integrity. Follow these troubleshooting steps to safely resolve the issue.

1. Run the Windows Memory Diagnostic Tool

Faulty RAM modules frequently corrupt kernel data structures and trigger this specific stop code.

• Press the Windows Key, type Windows Memory Diagnostic, and open the tool.
• Select Restart now and check for problems (recommended).
• Let your PC restart and complete the scan. Check the results in Event Viewer once back in Windows.

2. Check for Corrupted System Files

Damaged core system files can lead to critical security validation checks failing in the kernel.

• Right-click the Start menu and select Terminal (Admin) or Command Prompt (Admin).
• Type sfc /scannow and press Enter.
• After the scan completes, run DISM.exe /Online /Cleanup-image /Restorehealth.
• Reboot your PC when finished.

3. Update Your System Drivers

Outdated or legacy third-party drivers (especially antivirus, storage, or network software) are common culprits.

• Right-click the Start menu and open Device Manager.
• Look for any devices marked with a yellow warning triangle.
• Right-click them, select Update driver, and choose automatic search.
