The RAM can be the source of the problem that causes your computer to restart and to display the Kernel security check failure error. If the problem began after you swapped the RAM with a newer one, try to put the old RAM back. If it works fine with the old RAM, then the problem might be with the new RAM. For almost every motherboard, the manufacturer normally displays a list of RAM that have been tested with that motherboard.

You might want to check whether your new RAM is on the list or use one that is listed. Also, ensure that the RAM is properly fitted in the right place. You can also use the Memory Diagnostic Tool in Windows 10 to check for memory problems, including testing of the RAM on your computer. Various sources also pointed out that the error is very likely to result from driver incompatibility problems.

Viruses are a common cause of various BSOD errors, and it might be the case here, as well. So, make sure to run your antivirus software or at least Windows Defender and check if your computer is virus-free.

Solution 7 – Make sure drivers are up to date

Another common cause of BSOD errors in Windows 10 are outdated or damaged drivers. So, make sure all your drivers are up to date. If you’re not sure how to update your drivers, check out this article.

    3. Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.Automatically Update complete
      Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

Also, take a moment to think if you have recently installed a new update or updated any of your drivers such as a graphic card driver. If the problem started after you updated a driver, then it would be a good move to roll back to the old version of the driver. Keep in mind that a virus can also cause your system to misbehave, so before you perform any of the above procedures, it is advisable to first run a full system scan with your antivirus software.
