Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- Did you make any changes to the settings of your PC prior to the issue?
- When was the last time it worked fine?
- Have you tried any troubleshooting steps?
- What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824
Keep me posted for further assistance.
