Scan hard disk error

The recurring "KERNEL_SECURITY_CHECK_ERROR" message may be caused by a hard disk error. To scan and fix hard drive errors, first go to "Start -> File Explorer -> This Computer". Right-click on your hard drive and select Properties.

In the pop-up window, switch to the Tools tab and select Check. The Error Checking Tool will start checking for errors. It will automatically fix any errors found.

Try system restore

To try a system restore, go to the system's settings application and look for "Update and Security". Click "Recover" in the left sidebar.

Under Reset this PC, select Start. Select the "Keep My Files" option. This will remove the app and settings, but keep your personal files.

Uninstall the overclocking software

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

Physical check of hard disk and memory

This may not catch your attention at first, but you should make sure your hard drive and memory stick are completely plugged in and fixed. If they are loose, it may result in the BSOD you encounter. If you have spare parts, you can also try replacing your current hard drive and memory stick with spare parts to see if this helps. These hardware are likely to be bad.

Perform a virus scan

This is an easy solution to be overlooked. You may not think the problem you are having is caused by a virus, but it may be. Perform a full system scan to see if any malicious programs are lurking in the system.
