Now, if your operating system starts and only gives you this Kernel Security Check Failure error occasionally, follow the steps below:

Solution 1 — Update your PC

Solution 2 — Scan your PC

Run a full system scan to detect and remove any virus or malware that potentially sneaked into your PC. Malware may cause various issues on your computer, including the Kernel Security Check Failure error.

Perform a full system scan in order to detect any malware running on your computer. You can use Windows’ built-in antivirus, Windows Defender, or third-party antivirus solutions. We recommend Bitdefender – rated as Nr. 1 world’s best Antivirus it will find all the malware on your PC and completely eliminate the threats.

Here’s how to run a full system scan on Windows 10 Creators Update:

  1. Go to Start > type ‘defender’ > double click Windows Defender to launch the tool
  2. In the left hand pane, select the shield iconKernel Security Check Failure fix
  3. In the new window, click the Advanced scan optionKernel Security Check Failure fix
  4. Check the full scan option to launch a full system malware scan.

Note: If the antivirus cannot remove the malware it detected, first you should try installing a different antivirus to see if it works. If it does not, then you will most likely have to restore your operating system to a point where you did not had this issue or completely reinstall the operating system.

Solution 3 — Check your disk for errors

On Windows 10, you can run a disk check using Command Prompt.

Start Command Prompt as administrator and type the chkdsk C: /f command followed by Enter. Replace C with the letter of your hard drive partition.

As a quick reminder, if you do not use the /f parameter, chkdsk displays a message that the file needs to be fixed, but it does not fix any errors. The chkdsk D: /f command detects and repairs logical issues affecting your drive. To repair physical issues, run the /r parameter as well.

Note: This process can be time consuming. Depending on the hard drive’s memory, it can go between half an hour and two hours before it is done.

Solution 4 — Kernel Security Check Failure after overclock

If you overclocked your PC, this may explain why you’re experiencing Kernel Security Check Failure errors. Revert your PC to its default configuration and uninstall any overclocking software running on it. Then restart your device to see if the error persists.

Solution 5 — Run System Restore

If the problem started recently, run System Restore. If this issue occurred after you installed new software on your computer, this tool helps you to remove recently added apps and programs.

The System Restore option allows you to restore the previous well-performing system configuration without losing any files, except for a few customizable features and settings.

Windows 10 offers a series of advanced recovery option that allows users to clean install the OS. You can also use ‘Reset this PC’ recovery option.

    1. Go to Settings > Update & Security > click on Recovery under the left pane.
    2. Click on Get Started under Reset this PC > choose to Keep your files.
    3. Follow the on-screen instructions to complete the reset.

The steps above showed you how to fix the “Kernel Security Check failure” error message on your Windows 8.1 or Windows 10 PC.
