I captured the real image of the blue screen error.  The error shows this mensage: "stop code: kernel security check failure". Now I have to find the solution for this specific problem.

Thank you for replying with the detailed error message. 

I truly appreciate your patience and efforts.

As @Flower_Bud is out of the office today, I'm replying to you.

Did you try the steps suggested in the previous post by @@Flower_Bud. If yes and the issue still persists then let us continue to perform the following steps to isolate and fix the issue:

Corrupt Windows system files can slow down the computer and cause other problems. System File Checker (SFC) is a utility in Windows that scans for corrupted system files. If SFC finds a problem, it tries to replace the problem files from a cached version on your computer.

If System File Checker cannot replace the corrupt files, use the Deployment Image Service and Management Tool (DISM). DISM checks the corrupted files, then downloads and replaces the files through Windows Update.

Use the following instructions to run System File Checker.

1. In Windows, search for Command Prompt. In the search results, right-click Command Prompt, select Run as administrator, then click Yes.

2. In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the forward slash /.

3. Press Enter, then wait while System File Checker scans for corrupted files.

   When the scan completes, the results display on the screen.

   • If the file checker found and replaced any corrupted files, restart the computer, then check the performance.

   • If the file checker did not find any corrupted files or found corrupted files but could not replace them, then go to the next step.

4. If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files, then downloads and replaces the files using Windows Update.

5. In Windows, open a web browser.

6.    NOTE: You need to be connected to the Internet to use DISM.

7. In Windows, search for Command Prompt. In the search results, right-click Command Prompt, select Run as administrator, then click Yes.

8. In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each forward slash / in the command line.

   Press Enter, then wait while DISM works. This might take several minutes.

9. If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.

Incase the laptop continues to restart the you may perform a Windows Push Button Reset. This repairs your computer by reinstalling the operating system. This can be done either while preserving your personal data and customizations, or removing all your personal data: https://hp.care/2JA4ZCO

I sincerely hope this fixes the issue. Keep me posted for further assistance.

All the best! 🙂
