Fix 2: Use System File Checker

If there are some corrupt files, especially in the C drive, then they are bound to be the cause of concern. Manually finding these files might be a tough job at hand. Fortunately, Windows comes with a built-in Command Line tool that scans for all the corrupt files and fixes them accordingly. Here is how to use this tool:

1. Head over to the Start menu and type in CMD.
2. Launch the Command prompt as an administrator.
   
3. Type in the below command and hit Enter:

   sfc /scannow

   

4. It will now begin with the scanning process which might take some time. Once done, it will accordingly fix the issue.

You should then restart your PC. See if it is able to fix the Kernel Security Check Failure issue in Windows 10.

Fix 3: Using Memory Diagnostic

Windows also comes with a Windows Memory Diagnostic tool that checks for and fixes memory problems on your PC. But before executing the below steps, make sure to save your work and close all the background running apps.

1. Now search for Windows Memory Diagnostic from the Start menu.
2. Launch it and select Restart now and check for problems.
   
3. Your PC will now restart and the tool will diagnose for all possible RAM related issues. It will then take the necessary course of action.
4. After this, you should restart your PC again. When it boots up, check whether the Kernel Security Check Failure issue in Windows 10 has been fixed or not.

Fix 4: Scan Disk for Errors

Similar to System File Checker, Windows has another Command Line Tool known as Check Disk. It checks for file system errors and hard drive bad sectors issues and fixes them accordingly. To make full use of this tool, follow the below steps:

1. Launch the Command prompt as an admin from the Start menu.
2. If you only wish to view the errors but prefers to manually fix them, then execute the following command:

   chkdsk C:

   

3. Or if you want the tool to do its job for you (recommended), then the below command will come in handy:

   chkdsk C: /f

4. As you might have realized, the /f code tells the system that it needs to fix this issue, after completing the scan.

Anyways, once the process is done, reboot your PC. See if the Kernel Security Check Failure issue has been rectified or not.

Fix 5: Uninstall overclocking Software

if you have installed any overclocking software, then it might conflict with the proper functioning of the CPU and other related components. Hence to fix this BSOD error, you could consider resetting your system to default settings by uninstalling overclocking software.

Different software has a diverse set of instructions to disable their functions. So follow the one as instructed by your software. Once you have disabled or uninstalled it, restart your PC. Check if it fixes the Kernel Security Check Failure issue.

In some instances, the issue might not be that much technical but the culprit could just be a third-party app. The best way to test is to boot your PC to Safe Mode. When you do so, all the third-party apps would be disabled. Then if in safe mode you don’t face any BSOD issue, the cause might then be attributed to a third-party app.

While in the general case, it is recommended to enable all the apps one at a time, to recreate the issue and identify the culprit. However, recreating a BSOD error is never the right thing to do. What you could do in this regard is to check all the apps that you have installed after facing this issue. Then uninstall them one by one until the error is fixed. On that note, here are the required steps:

1. So search for Settings from the Start menu.
2. Then go to Update and Security and select Recovery from the left menu.
   
3. Under the Advanced startup section, click on Restart Now.
4. You will now be taken to the “Choose an option” page. Select Troubleshoot and click on Advanced options.
5. Now head over to the Startup Settings and click on Restart.
   

Once your PC boots into Safe mode, see if it fixes the Kernel Security Check Failure error.

Fix 7: Perform Advanced Scan

Likewise, if any malicious program, virus, or malware has sneaked into your system, then also you might get this BSOD error. In this regard, it is recommended to perform a deep scan of your PC. While there are many third-party antivirus software, we would be making use of the Windows built-in Defender program. Here’s how:

1. Head over to the Start menu and search for Windows Security.
2. Then go to the Virus and Threat Protection section.
3. Within that, click on the Scan option and select Full Scan.
4. Finally, click the Scan Now button situated at the bottom of the page.

The entire process would take some time. When the scanning is complete, reboot your PC. Check if it Kernel Security Check Failure error on your Windows PC has been fixed or not.
