Hello @Debbie3212 
If the whirring noise is constant, it may be related to the fan. Refer to this article- https://www.hp.com/us-en/shop/tech-takes/how-to-clean-your-laptop

If your computer is beeping and not switching on, identify the beep code- https://support.hp.com/us-en/document/ish_1997719-1528356-16

If you need more help, I would need the details of the model and the exact symptoms.
