Uninstall Overclocking Software

If you recently overclocked your PC, you may have inadvertently corrupted some files and caused the Kernel Security Check Failure error. Try disabling/uninstalling your overclocking software and see if this solves your issues.

Check Hard Drive and Ram Physically

This may not have occurred to you at first, but you should ensure that both your hard disk and memory sticks are plugged in all the way and secured. If they’re loose, this can cause the BSOD you’re encountering. If you have spares, you can also try swapping out your current hard disk and memory sticks with the spares to see if this makes a difference. It is very possible that these hardware items could be defective.

Carry Out a Virus Scan

This is a solution that is surprisingly easy to overlook. You may not think that the problem you’re experiencing is due to a virus, but this could be the case. Carry out a full system scan to see if there are any nasty bugs lurking on your system.

Wrapping Up

The “Kernel Security Check Failure” error and the accompanying BSoD on Windows 10 is quite frankly one of the most annoying errors you could encounter. However, as you can see, there is plenty of hope for a solution. While it may take you some time to try out the various possibilities, it’s worth a shot, and you should eventually find your magic bullet.
