Blue Screen: How to fix kernel security check failure

How to fix kernel security check failure.

So u are seeing a Blue Screen of Death or BSoD? well don’t worry so is everybody else.

Unfortunately, the kernel security check failure is one that is so serious that the error results in a BSoD.


What causes kernel security check failure?

The kernel security check failure can happen due to:

  • Memory problems
  • Outdated drivers
  • Viruses
  • Corrupted Windows system files
  • Security programs
  • A damaged or corrupted hard disk

The most common is incompatible drivers. especially after updating to Windows 8, 8.1 or 10.

In this case, the system shows the following error.


How to fix kernel security check failure?

Well…. Windows is showing a general error. and not one u can pinpoint in seconds.

so let’s start identifying the cause.

1. Memory problems.

u can identify memory problems with the Windows memory diagnostics tool of download and run Memtest86+

to run the windows memory diagnostics tool go to the Control panel in the search box typ “memory”.

or press WindowsKey+R and typ “mdsched” and hit Enter.


as u can see there are 2 options.

1. Restart and check directly.

2. wait until the next start.

If you’re an advanced user and want to adjust this tool’s settings, press F1 when the tool starts. You can change the following parameters.

  • Test — There are three types of tests, namely, basic, standard, and extended. Each of these tests is described on the screen and you can choose whichever you want.
  • Cache — Choose the cache setting
  • Pass count — Decide how many times you want the system to repeat this test.

After making the changes, type F10 to start the test.

if the tool comes up with error, replace the Memory module ore let someone replace it for u.

Corrupted Windows file system

To check if the kernel security check failure is due to a corrupted or damaged file system, run the system file checker tool.

or press WindowsKey+x and click on. “Command Prompt (Admin)” Windows 7, 8, 8.1 or Windows PowerShell (Admin) in Windows 10

crtlx Powershel open

type stfc /scannow in to the prompt and hit enter


now Windows is Verifying the Windows installation.

when the sfc scan is completed open “Command prompt” or “powershell” again and enter chkdsk /f



Driver issues

Driver Verifier is a good tool to check for driver incompatibilities. To open this tool, type “verifier” in the start menu search box and hit enter. Alternately, type “verifier/?” in the command prompt. Both these options should open the Driver Verifier.

Note: You’ll have to run this tool as an administrator.

Select “create standard settings,” which is the default and click next. You can also choose “create custom settings” to select individual options or settings. Some of your options are:

  • Automatic check — This option always checks the performance of the selected driver(s). In case of faulty behavior, the manager will ensure that the driver releases all resources before it’s unloaded.
  • Special pool — When you choose this option, the manager allocates a driver’s memory request from a special pool that’s monitored for overruns and underruns.
  • Force IRQL checking — In this option, the manager invalidates pageable code to prevent a driver from accessing paged memory at the wrong IRQL.
  • Low resources simulation — When you select this option, the manager randomly denies memory requests to a driver to test the driver’s ability to handle low resources.
  • Pool tracking — This option tracks if a driver has released all memory resources when it’s unloaded. This prevents memory leaks.
  • I/O verification — This option monitors a driver’s I/O handling capability, and in the process detects inconsistent I/O routines.
  • Deadlock option — This option monitors a driver’s spin locks and mutexes to check the driver’s ability to cause deadlocks.
  • DMA verification — This option checks the driver’s use of DMA routines to check for improper use of DMA buffers and map registers.
  • Security checks — The manager looks for common errors that can cause security vulnerabilities.

Depending on what you need, you can choose specific options.

Once you’ve selected your options, it’s time to choose the driver(s) you want to monitor. You can either pick individual drivers or choose from the built-in choices of the verifier manager.

  • Automatically select unsigned drivers — Good choice for testing on Windows versions that don’t require signed drivers.
  • Automatically select drivers built for older versions of Windows — Helps to check driver compatibility for newer versions of Windows.
  • Automatically select all drivers installed on this computer — Tests all the drivers installed on your computer.
  • Select drivers from a list — In this option, you can choose all the drivers you want to test.

Once you make your choices, click on finish and reboot the computer. On startup, the driver verification manager will check for driver inconsistencies.

In case of corrupt drivers, uninstall, reinstall, or update them.

Scan hard disk

Download and install speccy to see the S.M.A.R.T. status of the disk


if the status says good than the disk is properly not the problem.



When you can’t identify the problem, try checking for viruses and ransomware. Install the latest Windows updates and run the antivirus software. In case of viruses, take the necessary action to remove them from your computer.

Yes, kernel security check failure displays a BSoD, but this error happens due to many reasons like memory issues, viruses, driver incompatibilities, and hard disk failures. Try the above solutions to understand the cause of the error and to fix the same.
