When I start my computer, there's a error saying "the system has detected that a cooling fan is not operating...
Error System Fan 90B
I've followed up the Tuto on hp website (cleaning from the exterior possible dust) + tried a hard reset (which didn't work).
Any help please?
I can still work on my computer but I understand it's not recommended. Plus, it is much slower than usual...
Any help is really appreciated and welcome.

To fix this error, use the following steps:
Press Enter to clear the message and allow the system to boot to the Windows Desktop.
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 Reducing Heat Inside the PC.
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 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.
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.
Have the computer serviced to clean internal components and replace the system fan if necessary. Make sure to address the following items when servicing:
Thoroughly remove dust from all internal cooling components.
Make sure wires from the system and CPU fans are connected securely to the motherboard.
Confirm the system fan blades spin correctly, and the fan is not producing loud noises. If not working correctly, replace the system fan.
Remove old thermal compound from integrated circuits and heat sinks and replace with new thermal compound.
Let me know how that pans out,
