    Hi, @Rodolfo Juarez Rivera

    If you haven't already, please check the exact warning shown when the PC starts. A fan/cooling warning on an HP All-in-One can indicate restricted airflow, dust buildup, or a cooling fan that is not working properly.

    To help narrow this down:

    1. What is the exact warning or error code shown, such as "System Fan (90B)"?
    2. What is the exact model of the HP All-in-One?
    3. Does the PC become unusually hot, shut down, or can you hear the fan running?

    For now, make sure the air vents are not blocked and avoid heavy use if the PC is overheating or the fan is not spinning, since this may require the fan to be cleaned or serviced.
