@Dmurray1966 Welcome to HP Community!

 

I understand that you are getting 90 errors while startup.

 

  • CPU Fan not Detected (900) CPU Fan is not detected or may have malfunctioned

  • CPU Fan Speed Failure (909) The system has detected that a cooling fan may not be working properly.

  • System Fan (90b) The system has detected that a cooling fan is not operating correctly.

  • System Fan Speed Failure (90f) This error indicates that a problem exists related to the heat removal system.

  1. Press Enter to clear the message and allow the system to boot to the Windows Desktop.

  2. Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.

    For more information on reducing heat inside your computer, see the following:
  3. After you remove the dust, turn on the computer. If the error message persists, continue with these steps.

  4. Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.

    For more information on performing a hard reset, see Use Hard Reset to Resolve Hardware and Software Issues.

  5. In some cases, updating the BIOS might help prevent this error from occurring.

    For more information on how to update the BIOS, see Updating the BIOS.
