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:

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?

Our customer support will provide only case ID number not EXTENSION ID however let’s try these steps to resolve the problem:

• I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 
• If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.
