Hi Tonynut,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion Notebook and a clicking sound from possibly the hard drive or fan. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to perform a hardware test.
Hope this helps you.
Thanks.
