Kernel is the central component of the Windows Operating System that mediates access to its resources, controls functioning of the OS, and acts as an interface between a computer’s hardware devices and software applications.
If you ever come across a Blue Screen of Death (BSOD) with Kernel_Security_Check_Failure error, it indicates a critical problem with the functioning of your computer. You might want to consider various aspects that might have triggered this situation.
Block Offending Drivers
The only way to stop execution of the offending drivers – computing programs that control functioning of your peripheral devices, is by loading your OS into the Safe Mode. The easiest way to do so is given below:
1. Click the Start button.
2. Click on the Power icon.
3. Press and hold the Shift key and click on the Restart option.
4. Release the key now.
5. Your computer will automatically reboot into the Safe Mode.
Perform Windows Update
Most computers have Windows Update program set up to automatically download and install new updates as soon as they are released, which is the recommended way. However, if your computer is set to manually scan for updates, you may want to follow the steps given below:
1. Click on Start, select Settings.
2. Click the Updates and Security icon.
3. Click the Windows Update tab.
4. Click on Check for Updates to download and install new updates.
Perform Hard Disk Check-Up
Often a Hard Disk or an SSD (Solid-State Drive) will have a slow death, staying functional until a specific period of time. This error could have been caused by critical disk errors, bad sectors across the disk. It is highly recommended to perform HDD diagnostic if your computer repeatedly encounters Kernel Security Check Failure along with a strange sound emanating from the hard disk.
1. Double-click the This PC icon on your Desktop.
2. Right click your system drive (for example: C:\), select Properties.
3. Click on the Tools tab and then Check Now.
4. Click Scan Drive in the confirmation prompt.
Check for Operating System Corruption
STOP Error Kernel Security Check Failure may indicate corruption of the protected operating systems files and components. Using System File Checker – a pre-installed tool, overwrite corrupted file versions with a cached copy of original files located in the DLL Catches sub-folder of the System32 directory.
1. Press Windows Key + X, select Command Prompt (Admin).
2. Type the following command and hit Enter:
- SFC /ScanNow
3. After successful compilation, restart your computer.
Perform System Restore
System Restore is an integral part of your operating systems that back-up the System Registry before making critical changes to your computer. When your computer stops functioning at all or a STOP error occurs, as in your case, you can simply roll back your computer to a previous point in time.
1. Right-click This PC, select Properties.
2. Click Advance System Settings.
3. It opens up the System Properties dialogue box with various tabs.
4. Click the System Protection tab and then System Restore.
5. You will be prompted to either select a system generated recent restore point or a user created one.
6. Follow the on screen instructions.
Use Driver Roll Back Feature
Do you experience BSOD Kernel Security Check error after updating your drivers? It’s more likely a faulty driver update might have caused it. You need to roll it back to the previous version. You can accomplish this task using Device Manager, a tool that lists out and manages all devices.
1. Press Windows Key + X.
2. Select Device Manager.
3. In the new screen, expand the computer name and right-click a newly updated device.
4. Select the Properties option.
5. Click the Driver tab and then Roll Back button.
