How Do I Fix A BSOD Caused By Kernel Security Check Failure In Windows 10?

There are four effective techniques for resolving the kernel security check failure listed below. If one method does not work for you, try a different one. These techniques will undoubtedly solve your problem.

1. Change The Default Graphics Processor

When a computer has two graphics cards, the heavier programmes may run on the weaker of the two. Assume you’re running a resource-intensive programme that makes use of the integrated graphics hardware.

The computer terminates the software and displays this error because that graphics driver is less powerful than the Nvidia GPU. This condition necessitates a modification in such programmes’ default graphics processor.

You can avoid this mistake from annoying you by making a few changes. To learn how to change an application’s default graphics card, follow the steps below.

Step 1: Select Nvidia control panel from the context menu by right-clicking anywhere on the desktop.

Step 2: In the left pane of the window, look for the 3d settings option.

Step 3: Next, select Manage 3D Settings from the drop-down menu.

Step 4: Select the Program settings tab in the right pane.

Step 5: Select the programme that is causing the error from the first drop-down menu.

Step 6: Select High performance Nvidia processor from the next drop-down selection titled: select the preferred graphics processor.

Step 7: Finally, save your modifications.

Finally, reboot your computer.

Step 9: Launch the application/program, which should now run smoothly. Otherwise, proceed to the next step.

 2. Install the Latest Nvidia GPU Driver

It may be time to upgrade your Nvidia graphics driver if you haven’t done so in a while. A common problem that impacts the performance of your graphics card is an outdated version. It’s possible that the version of Nvidia card you’re using has a glitch.

As a result, your computer will display the error Kernel security check failed BSOD. It’s tough to say which Nvidia GPU versions have issues because there are so many. As a result, the most practical approach is to upgrade to the most recent version.

To update the driver, go through the procedures below:

Step 1: Open the official Nvidia Geforce page in your PC’s browser.

Step 2: Next, navigate to the area for drivers.

Step 3: Next, check for the option to search for drivers manually. Fill in the type and series of your Nvidia GPU, the model number of your Nvidia driver, your computer’s operating system, and the language you want to use, then hit search.

Step 4: Select the most recent driver from the list of suitable drivers.

Step 5: Download the driver as well as the installer.

Step 6: Now open the installer and follow the on-screen instructions.

Step 7: The process will erase the existing driver and install the new one on your computer.

Step 8: The application should now run without issues after the installation is complete.

To fix bugs, the company releases new versions on a regular basis. To avoid future problems, make sure you check for updates on a regular basis.

 3. Downgrade Your Nvidia GPU’s Driver Software To An Older Version

If updating the driver didn’t fix the problem, lowering the driver might. Rolling back to an older version (after trying out the newer) will help if the problem is with the version. Older versions have a higher level of stability and are less prone to failure.

Despite the fact that they would have less features, they would be able to correct this problem. So, if your GPU didn’t get any updates in step 2 or the latest version didn’t fix the problem, try these steps.

You won’t be able to use this procedure if the rollback driver option is greyed out. It means you won’t be able to downgrade your driver version. This is common with integrated graphics cards like the Intel HD. As a result, if you use Nvidia, you should be alright.

Step 1: Press the Windows key + R to bring up the run-dialog box.

Step 2: Now type devmgmt.msc into the search box and press Enter.

Step 3: To reveal the contents of Display adapters, click the arrow beside it.

Step 4: Right-click the Nvidia graphics card and select Properties.

Step 5: In the properties box, click the Drivers tab.

Step 6: Select Roll Back Driver from the drop-down menu.

Step 7: After that, click yes and follow the on-screen instructions.

Play the application after it has been downgraded to see if the error has been resolved.

 4. Remove The Sniffer.exe File 

This solution is very useful for those who are experiencing a Kernel security problem when launching Photoshop. These individuals were able to resolve the problem by deleting the sniffer.exe file (sniffer gpu.exe).

Remove this file from the directory; it will not corrupt Photoshop, but it will fix the problem. To put this method to the test, perform the following:

Step 1: Double-click the My computer icon to open the file explorer. Alternatively, hold down the Windows key and press E.
