HI MiriamSPia:
Welcome to the forum!
Thank you for you inquiry. I will do my utmost to assist you!
I would run the HP PC Hardware Diagnostics UEFI to have it test the hardware. I would also suggest running the HP Support Assistant to aid in updating drivers and resolving issues. You can also go into Device Manager and uninstall the driver and then run Windows update to have it look for an updated driver. If you are still experiencing a difficulty , I would suggest posting it in the commercial forums, to get your issue more exposure, since this is a commercial product. You can do this at http://h30499.www3.hp.com/hpeb/ .
I hope this helps.
