Stop Code KERNEL SECURITY CHECK FAILURE (Windows 10) – Fixed

BSOD error messages are annoying and damaging for your computer, stopping you from conducting your typical PC activities. But you can still fix them without having to factory reset Windows.

Fix KERNEL SECURITY CHECK FAILURE Error

What is KERNEL SECURITY CHECK FAILURE?

KERNEL_SECURITY_CHECK_FAILURE is a Blue Screen of Death error message that halts all activities on your computer and prevents it from running properly.

It usually happens because a file compatibility verification failed, which means that the file should be repaired, updated, or replaced.

However, there could be various other causes why you receive the KERNEL SECURITY CHECK FAILURE stop code, such as outdated drivers, malware infection, memory issues, faulty security software, corrupt system files, or hard disk errors.

Stop Code Fix for KERNEL_SECURITY_CHECK_FAILURE

Since it’s a BSOD stop code, repairing KERNEL SECURITY CHECK FAILURE on Windows 10 and older Windows versions depends on whether it was triggered by software or hardware issues.

Software problems are easier to resolve. When it comes to troubleshooting hardware errors, though, you have to get your hands dirty.

Before attempting to make significant modifications to your computer and operating system, you should create a system restore point. It allows you to revert Windows to a stable state, if necessary.

Furthermore, if your system enters a reboot loop due to the KERNEL SECURITY CHECK FAILURE issue, you should boot Windows in safe mode.

1. Make sure your drivers are new and compatible

If your computer’s drivers aren’t working properly, it could be why your screen becomes blue and shows stop code KERNEL SECURITY CHECK FAILURE. Otherwise, you might have missing drivers, which you can easily fix.

Here’s how to reinstall drivers:

  1. Right-click the Start button on Windows 10 and select Device ManagerWindows 10 shows how to access Device Manager from the Start right-click menu
  2. Select and right-click a device, then click Uninstall deviceWindows shows how to uninstall a device from Device Manager
  3. Proceed with the device removal and restart your computer. The driver will be reinstalled automatically
  4. Do this for all your devices

Here’s how to update drivers:

  1. Go to Device Manager, right-click a device, and select Update driverWindows shows how to update display adapter drivers in Device Manager
  2. Click Search automatically for updated driver softwareWindows 10 shows how to search automatically for updated driver software
  3. If you get the The best drivers for your device are already installed message, click Search for updated drivers on Windows Update

Unfortunately, Windows often fails to find newer updates online, even when looking into Windows Update.

To solve this problem, you can manually identify your driver version and find a newer one on the manufacturer’s website, then download and install it. You can use a tool like DriverVerifier to detect your current drivers.

It’s a time-consuming process, however, especially if you need to update more than one driver. Instead, we suggest opting for driver updaters. These software applications are capable of updating multiple drivers at the same time.

2. Unplug all external hardware devices

If any of your peripheral devices are faulty or not compatible with your operating system and computer, it could cause various issues like the KERNEL SECURITY CHECK FAILURE error.

For instance, it’s a good idea to compare your hardware with the official Windows 10 specs to ensure that everything’s correct.

Or, there might be a problem with your USB ports, not the gear itself. To test this theory, simply connect your USB-enabled devices to different ports.

However, it that doesn’t solve the problem, then unplug everything. Confirm that you’re not receiving the BSOD message anymore and start replugging your gear one piece at a time to identify the guilty party.

3. Get the newest Windows updates

Make sure to download and install the latest Windows updates on your computer. This way, you can take advantage of the newest features, improvements, and security patches.

  1. Open the Start menu, type Check for updates, and press EnterWindows 10 shows how to check for system updates
  2. Wait until Windows looks for updates. If there’s anything pending, click DownloadWindows 10 shows how to download system updates

4. Disable your overclocking tools

Many gamers resort to overclocking utilities to get more power from their computer, in order to improve the system requirements for their favorite games.

Using an overclocking tool means modifying your RAM, CPU, and GPU settings. Regrettably, this could also lead to BSOD error messages like KERNEL SECURITY CHECK FAILURE.

To fix this, you have to deactivate your overclocking software and reset your clock settings to default.

5. Run a malware scan

If your computer was infected with dangerous malware agents, they could have hijacked your operating system and disabled your current processes.

As a result, you might experience system stability problems and BSOD errors like KERNEL SECURITY CHECK FAILURE.

Just fire up your antimalware application and run a scan to get rid of any infected files on your PC. If you don’t have a third-party tool installed, then you can use Windows Defender:

  1. Press the Win key, type Windows Security, and open this appWindows 10 shows how to access the Windows Security app

  4. Type y and press Enter when the tool asks to schedule the scan at the next Windows boot
  5. Restart your computer and wait until CHKDSK finishes its job

If your hard disk has errors, you can trust the Check Disk utility to solve them. However, if the KERNEL SECURITY CHECK FAILURE error persists, proceed to the next solution.

Continue with SFC (System File Checker):

  1. Run CMD with admin rights
  2. Type sfc /scannow and hit Enter. Once the scan is complete, SFC will try to fix any corrupt system files it findsWindows shows how to run the sfc scannow command in CMD
  3. Reboot your PC

System File Checker is great for fixing corrupt files that belong to Windows and which may trigger Blue Screen of Death errors. But, if it doesn’t work either, it’s time to bring out the big guns.

Finish with DISM (Deployment Image Servicing and Management):

  1. Open Command Prompt as admin
  2. Type DISM /online /cleanup-image /scanhealth and press EnterWindows 10 shows how to run DISM /online /cleanup-image /scanhealth in CMD
