Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Use HP PC Hardware Diagnostics even if the computer does not open to Windows. Start with the Quick Test (2 to 3 minutes). If the Quick Test does not find a problem, run the Extensive Test (2 hours or more). The Extensive Test includes a Loop Until Error option.

NOTE: If the test cannot run and the Hard Disk Does Not Exist message displays, contact HP Customer Support for assistance.
  1. Plug the AC adapter into the computer.

  2. Press the Power button for at least five seconds to turn off the computer.

  3. Turn on the computer and start pressing Esc repeatedly, about once every second. When the menu appears, press the F2 key.
  4. When the HP PC Hardware Diagnostics menu displays, click Component Tests.

  5. In the Component Tests menu, click Hard Drive, and then click Quick Test.

  6. Click Run once.

  7. The Hard Drive Quick Test begins. If the computer has more than one hard drive, select the drive you want to test. To test all the hard drives, select Test All Hard Drives.

    When the test is complete, the screen displays the results.

Hope this helps! Keep me posted for further assistance.
