SECURITY SYSTEM (0X00000029) Blue Screen Fix Guide (Windows 10/11)

How to Fix SECURITY_SYSTEM (0x00000029) Blue Screen

###

Method 1: Run System File Checker (SFC) and DISM

The first step in troubleshooting is to repair corrupted system files using built-in Windows tools. These commands scan for and restore missing or damaged files.

• Open Command Prompt as Administrator:
  • Press Win + X and select “Terminal (Admin)” or “Command Prompt (Admin).”
  • If prompted by UAC, click “Yes” to grant permission.
• Run System File Checker (SFC):

  sfc /scannow

  Wait for the scan to complete. If no errors are found, proceed to DISM.

• Run Deployment Image Servicing and Management (DISM):

  DISM /Online /Cleanup-Image /RestoreHealth

  This may take several minutes. Restart your PC after completion.

Method 2: Run CHKDSK to Check for Disk Errors

If the error is related to disk corruption, running CHKDSK can help identify and fix issues on your storage drive.

• Open Command Prompt as Administrator (as above).
• Run CHKDSK:

  chkdsk C: /f /r

  Replace “C:” with your system drive letter if needed. If the disk is in use, youll be prompted to schedule the scan on the next restart.

• Restart your PC and let CHKDSK run automatically during boot.

Method 3: Update or Roll Back Drivers

Outdated or incompatible drivers are a common cause of this error. Follow these steps to update them:

• Open Device Manager:
  • Press Win + X and select “Device Manager.”
  • Expand categories like “Display adapters,” “Network adapters,” or “Storage controllers.”
• Update Drivers:
  • Right-click on a device, then select “Update driver.”
  • Choose “Search automatically for drivers” and follow the prompts.
• Roll Back Drivers (if available):
  • If updating doesnt work, right-click a device and select “Properties.”
  • Go to the “Driver” tab and click “Roll Back Driver.”

Method 4: Disable or Reinstall Security Software

Third-party security software, such as antivirus programs, can sometimes conflict with Windows’ built-in security features.

• Uninstall Antivirus Temporarily:
  • Go to “Settings” > “Apps” > “Apps & features.”
  • Find your antivirus program, click it, and select “Uninstall.”
• Restart Your PC: Reboot after uninstalling the software.
• Check for BSODs: If the error doesnt reappear, reinstall a trusted antivirus program.

Method 5: Perform a Clean Boot to Identify Conflicts

A clean boot starts Windows with only essential drivers and services, helping isolate software conflicts.

• Open Task Manager: Press Ctrl + Shift + Esc.
• Go to the “Startup” tab: Disable all startup items by right-clicking each and selecting “Disable.”
• Use msconfig:
  • Press Win + R, type msconfig, and press Enter.
  • Go to the “Services” tab, check “Hide all Microsoft services,” then click “Disable all.”
  • Go to the “Startup” tab and click “Open Task Manager” to disable remaining items.
• Restart Your PC: If no BSOD occurs, a third-party program may be causing the issue. Re-enable items one by one to identify the culprit.

Method 6: Check for Windows Updates

Microsoft frequently releases updates that fix security-related bugs. Ensure your system is up to date:

• Go to Settings: Click “Update & Security” > “Windows Update.”
• Click “Check for updates”: Install any pending updates and restart your PC.
• If no updates are available, manually check:
  • Go to “Advanced options” > “Optional updates.”
  • Install any driver or security-related updates.

Method 7: Reset Windows (Last Resort)

If the error persists, a clean installation of Windows may be necessary. Back up your data first:

• Back Up Important Files: Use an external drive or cloud storage.
• Create Installation Media:
  • Download the Windows 10/11 Media Creation Tool from Microsoft.
  • Follow the prompts to create a bootable USB drive.
• Reinstall Windows:
  • Boot from the USB, select “Install now,” and choose your language settings.
  • Select “Custom: Install Windows only (advanced)” to preserve personal files if needed.
