Here are the steps to identify the problem.

  1. Corrupted Windows Files
  2. Driver Issues
  3. Memory Checkup
  4. Scan Hard Disk for Errors
  5. Check for Malware

1. Corrupted Windows Files

As mentioned above, some programs can modify some windows essential files, thus making them corrupt. In this case, you have to restore the deleted or mishandled files, and then the error will go of it own. To do this, you have to run the Windows file checker tool.

You don’t have to download this tool, and this is already present in the WIndows. You can search this tool in the search box, or if you are a CMD fan then, run CMD as administrator and type

Select Standard Settings and click Next. You will see some options here. You can choose the option according to your requirements. Here are the details of each option; it will help you to choose the best option for you.

  • Automatically Select and Assign: This option makes sure that the selected driver is working fine, and if the driver is not working right, it should be removed.
  • Special Pool: On selecting this option, the verifier designates the driver’s memory from a private pool that is for overruns and underruns.
  • Low Resource Simulation: On choosing this option, the verifier denies the memory requests to a driver to test its ability to handle the low resources.
  • Pool Tracking: This, when chosen, take extraordinary measures to prevent memory leaks.
  • Deadlock Option: This option helps to identify the deadlocks of drivers because of the driver’s spin-locks.
  • DMA Verification: If you want to check the DMA buffers and map registers of the drivers, then you should select this option.
  • Security Checks: This option does a scan to check for viruses and errors that cause the vulnerabilities.

If your system has corrupted drivers or something, then you will get to know after this. Now when you know that what driver is causing the kernel security check failure, you can reinstall, update or delete that.

3. Memory Checkup

First of all, if you have changed the RAM recently then make sure that it is compatible with your system. If there are no issues here, then you have to run the windows memory diagnostic tool.

Windows 10, 7, and 8 have this tool. To run this tool type memory in the search bar, you will see the tool, run this.

4. Scan Hard Disk for Errors

As mentioned the possible cause of kernel security failure can be hard disk error. First of all, make sure the disk you use is perfectly fine in health and compatible with your machine. If your hard disk is fine, then you have to scan for the errors. You can do so by using the Windows chkdsk utility tool that has the power to study for every possible fault with the disk you are using.

From windows 8 to onward, there is no need for this scan, but as we are facing a blue screen issue, most probably the auto disk scan has been disabled by some software. You can do that manually, open CMD and type:

 chkdsk /f c: 

After the successful scan, if there are some errors in the disk, they will be fixed automatically on the next restart.

5. Check for Malware

Windows is an open-source system, and any kind of virus or malware can attack your files thus can make things messy. You can always rely on windows defender because it is not that powerful and it is a part of the windows, so its activity can be frozen.

You can purchase good software like Avast.

These were some of the Quick fixes that you can apply in the case if you don’t have Windows installation media.
