@Ebunapex, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

We see that you are facing System Fan (90B) error. 
To resolve the error, please try the following steps.

• Press enter to clear the message and allow the system to start to the Windows desktop.
• Turn off 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.
• After you remove the dust, turn on the computer. If the error message persists, continue with these steps.
• Perform a hard reset. Performing a hard reset can reset recorded thermal values in the memory and enable you to use the computer for a short time to access and save important files before service.
   

Please follow this document to perform the subsequent steps - HP PCs - 900, 901, 909, 90A, 90B, 90E, 90F, 911 error is displayed on a black screen | HP® Support
 

I hope this helps.
