Thank you for posting on HP Community,

For an accurate solution I'll need more details:

What is the product number of your device? Use this link to find it: click here

(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc.)

Have you attempted any steps on your own before posting on the HP Forums?

When was the last time it worked without these issues? 

Did you run a hardware test on the computer using the F2 key during a restart?

In the meantime, please try the steps mentioned on this link: Click here (related post)
