    Go to this guided instruction here for the “To fix the "Kernel Security Check Failure" error in Windows, you can try the following steps. As Acer does not have anything specifically for this error and its not a common error across the board, it must be with your Acer products. Good luck and hope this helps you out.

    Or do the following:

    1. Run System File Checker (SFC) to check and repair corrupt Windows files.
    2. Start your PC in Safe Mode.
    3. Run Windows Memory Diagnostic Tool.
    4. Use Windows System Restore.
    5. Update Windows 10.
    6. Run CHKDSK Utility.
    7. Scan your PC for malware.
    8. Perform a Factory Reset.

    A "Kernel Security Check Failure" blue screen error on an Acer laptop often indicates a problem with the operating system's core, typically caused by outdated or corrupted drivers, malware, or hardware issues. To resolve this, consider updating drivers, scanning for malware, running system file checker, and checking for hardware problems.

    Here's a more detailed breakdown of potential causes and troubleshooting steps:
    Possible Causes:
    Outdated or Corrupted Drivers:
    Drivers are essential for hardware components to communicate with the operating system. If they are outdated or corrupted, they can cause system instability and lead to the blue screen error.
    Malware:
    Viruses and other malicious software can interfere with system processes and cause the kernel to malfunction.
    Hardware Issues:
    Faulty RAM, hard drive problems, or overheating can also trigger this error.
    Corrupted System Files:
    System files are crucial for Windows to operate correctly. If they become corrupted, it can lead to various errors, including the "Kernel Security Check Failure".
    Conflicting Software:
    Sometimes, newly installed or problematic software can clash with the operating system, causing the blue screen.

    Troubleshooting Steps:
    1. Update Drivers:
    Open Device Manager (search for it in the Windows search bar).
    Expand the categories and right-click on devices to update their drivers automatically.
    Alternatively, visit the Acer support website for your specific laptop model to download the latest drivers.
    2. Scan for Malware:
    Run a full scan with your antivirus software.
    Consider using Windows Defender Offline if the standard scan doesn't detect anything.
    3. Run System File Checker (SFC):
    Open Command Prompt as an administrator.
    Type sfc /scannow and press Enter.
    This will scan and repair corrupted system files.

    4. Check for Hardware Issues:
    RAM: Run Windows Memory Diagnostic tool to check for RAM errors.
    Hard Drive: Check the hard drive for errors using the chkdsk command in Command Prompt (as administrator): chkdsk /f /r.
    Overheating: Ensure proper cooling and ventilation for your laptop.
    5. Boot into Safe Mode:
    Start your laptop and press the F8 key repeatedly during startup to access the Advanced Boot Options.
    Select "Safe Mode" or "Safe Mode with Networking".
    If the error doesn't occur in Safe Mode, it indicates a driver or software conflict.

    6. System Restore:
    If you have a restore point, use it to revert your system to a previous state.
    You can access System Restore through the Recovery options in Settings.
    7. Uninstall Problematic Software:
    If you recently installed any new software, try uninstalling it to see if it resolves the issue.
    8. Consider a Clean Boot:
    Perform a clean boot to start Windows with minimal drivers and startup programs. This can help isolate the problematic software or driver.
    9. Check for Windows Updates:
    Ensure your Windows is up to date by checking for updates in Settings.
    10. If all else fails, consider reinstalling Windows:
    This is a more drastic step, but it can resolve persistent issues if other troubleshooting steps don't work.
