Fix Kernel Security Check Error in Windows 10

1. Look for memory-related errors on your PC (Windows Memory Diagnostic Tool).

RAM plays a very important role in the functioning of your computer. The system should boot. The higher the amount of CPU memory, the better the performance of your computer. If one of them fails, your system becomes slow. If the entire RAM fails, then the system does not work at all.

You must find and fix problems in your system by displaying corrupted or faulty RAM systems. This can be done using the Windows Memory Diagnostic Tool.

The Memory Diagnostic Tool is a utility that looks for problems in your system’s RAM and fixes them. Here are the steps to troubleshoot CPU memory related issues:

1. Open the Run tool on your computer by pressing the Windows and R keys at the same time.
2. In the open field, type mdsched.exe and press the Enter key.
3. Another way to open this tool is through the search box where you can find the memory diagnostic tool.

1. This will open the memory diagnostic tool in the form of a small dialog box with two options, namely:
   • Restart now and check for problems
   • Check for problems and the next time I turn on my computer
2. You can choose one of these options. Either way, the RAM will be checked for problems. Follow the instructions from the windows that appear on your screen.

If any problems are found, you may have to fix the problem by connecting new RAM to the motherboard. If you are unable to run the Memory Diagnostic Tool, try starting your computer in Safe Mode, and then open the tool.

2: Take a look at the memory slot and hard drive

This issue can be caused by a loose RAM (Random Access Memory) stick or a loose hard drive. You will have to open the processor case to look at them as they are connected to the motherboard.

The RAM may have popped out of the slot or the retaining tab may have broken, causing the connection between the RAM and the motherboard to be loose.

In this case, the RAM will not be detected. If you have more than one stick of RAM, the rest will be detected, except for the badly connected one. If only one RAM is present, your system will not boot until the issue is resolved.

Improper connection of the hard drive or damage to this hardware can also cause this problem. If you have an additional drive, you can check if the problem exists on another hard drive.

3: Scan for hard drive errors and fix them

Hard drive errors can cause kernel security checks to fail. You can see if you have errors and fix them so that this problem does not cause you to blue screen of death. Explorer has a scanning feature that can detect errors.

Here are the steps to check and find errors:

Note. This method must be performed by an administrator because some aspects of this procedure require access to the system through an administrator profile.

1. Press the Ctrl and E keys together to bring up File Explorer. The easiest way to open this is by clicking the folder icon on the taskbar.

1. If you have partitioned your hard drive, you must know which partition contains Windows system files and the operating system. This is usually the C:/ drive. This is known as the system drive.
2. Right-click the drive and select Properties from the pop-up menu.

1. The system disk properties windows will appear on the screen. Click the “Tools”tab in this dialog box.
2. In the Error Checking section, click the Check button. This must be done by the administrator.
3. Select the Scan Disk option to start checking for errors. The duration of this scan depends on the number of files on the system drive.

1. When the results appear and you notice problems on your drive, the tool offers instructions on how to fix the problem.
2. Do as instructed on the window to get rid of this problem.

4: Temporarily disable your antivirus

Antiviruses are useful software. But not all the time. They are overly protective and may prevent you from performing certain security functions.

They block certain processes and programs from running when they are active. These missing processes can cause the kernel security check to fail on your computer. You can disable your antivirus and see if the issue still exists.

Here are the steps to deactivate the antivirus:

1. Open the Task Manager with the keyboard shortcut (Ctrl + Shift + Esc) or by right-clicking on the taskbar and selecting Task Manager.
2. Click the “More Info”button to see a list of all processes running on the computer.
3. Click the Startup tab and find the antivirus program on your computer.
4. Select a process and the “Disable”button in the lower right corner of the window will be highlighted.

Click on it to stop the application from starting the next time you restart your computer.

1. Restart your computer. You wouldn’t see a kernel security check fail if an antivirus was the culprit.
2. If the antivirus is not the cause, you can follow the steps above and go to the Startup tab, where you must click the Enable button after selecting the antivirus program.

Before you decide to disable the antivirus on your system, you must remember that this software protects your computer from viruses and malware. Deactivating this may put your computer at risk. If you don’t want to endanger your system, skip this method.

5: Start Windows 10 in safe mode.

Safe Mode is a feature of Windows that allows you to start the OS with minimal and necessary features. If the Kernel Security Check Error disappears in Safe Mode, you can safely assume that one of the applications on your computer is causing this error. Removing this program will help.

The Legacy Advanced Boot Menu or F8 Safe Mode is one of the most important factors needed to access and boot your computer in Safe Mode.

Users cannot start Safe Mode on their crisis computers if this boot menu is disabled. Enabling this is also a solution to fix your system’s kernel security check error.

Here are the steps to enable the Legacy Advanced Boot menu on your system:

1. You will be asked if you want to schedule a disk check when the computer restarts again. Press the Y key and press Enter.
2. Restart your computer for the command to check the files.

11: Run a System File Checker

The System File Checker or SFC Scan is a Windows command that can help check device drivers for corrupted files and bring them back to working versions. You can use this to get a configuration where the kernel security check error does not exist.

Here are the steps to take:

1. Open a command prompt window with administrator rights. Type command prompt or cmd into the search bar and select “Run as administrator”from the results.
