How to Fix Kernel Security Check Failure Errors?

Sometimes, uninstalling a driver or updating is all that’s needed. It may take a little more time to identify and fix this problem. You can locate the problem quickly by starting with simple fixes and then moving on to more complex ones.

Fix 1: Remove all removable peripheral devices

Remove any peripheral devices that may cause interference before you begin troubleshooting. Remove any removable items, such as flash drives or CDs. This could lead to a kernel check failure error if any of the items have loose or damaged connectors. Windows will connect first to these items at startup. If the error persists, restart the computer. If not, continue troubleshooting.

Fix 2: Scan malware

The error message could have been caused by a virus or malicious software. Search for and remove malware using Windows Defender or another antivirus software. After finishing, reboot your computer and try troubleshooting again if you still get the error.

Fix 3: Disable Windows auto-restart

Stop the computer from automatically restarting when the BSOD appears. This will give you the chance to start troubleshooting.

Fix 4: Start Windows in Safe Mode

You may find the problem by booting with only essential programs running. Use the button if necessary to perform a hard restart. Uninstall any programs that you added before the kernel failed the security check. Restart your computer, and then try again. Continue troubleshooting if the error persists.

Fix 5: Update drivers

One of the most common causes of this problem is a corrupt device driver. Install any driver updates that are available using Device Manager. Restart the computer once you’ve done this. If the error persists, continue troubleshooting.

Fix 6: Update Windows

Windows updates are usually installed automatically. However, you may not have downloaded an update that could fix the problem. Windows will need to restart after any updates. Check to see if you still have the same error.

Fix 7: Scan your RAM to identify possible problems

Windows Memory Diagnostic was formerly available through Microsoft but is now available to download for free from a trusted source. There are also many free memory tests that you can use. After using the tool, restart the computer. Continue troubleshooting if the error persists.

Fix 8: Check for corrupt files by scanning the system.

The System File Checker allows you to find problems in Windows files that are protected. The tool will replace any damaged files it finds. If the error persists, restart the computer. If not, continue troubleshooting.

Fix 9: Check for hard disc errors

The Error Checking Tool is another tool that comes with Windows. You can use it manually to find and fix errors on your hard drive. A reboot is necessary after using the error-checking tool. Continue troubleshooting if the error persists.

Fix 10: Restore the system to its previous working point

Windows System Restore can undo any changes that may have caused the problem, taking the computer to a time when it was working correctly.

Fix 11: Use the Startup Repair Tool

Run the Startup Repair Tool if you continue to see the BSOD on your computer when it boots up. This will automatically fix any issues. Startup repair, formerly known as automatic repair, is an efficient tool for fixing a computer that is not starting properly. Startup Repair can be found in the Advanced Startup Options.

Fix 12: Reset your computer

If all other troubleshooting methods have failed, you can use Reset This Computer in Windows 10 and Windows 8. You can choose to either keep all your files or delete them, or to restore the computer’s factory settings. This option is not recommended if you do not want to have to rebuild your computer from scratch.


It can be difficult to fix the Kernel Security Check failure error, but if you follow these steps, your system will return to normal. Updating drivers and scanning your system for malware can prevent future errors.
