@edpgamer,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

Don’t worry, I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details.

• When was the last time the computer was working fine?
• Have you made any software or hardware changes on the computer?
• Have you performed any troubleshooting steps before posting?

While you respond to that, I recommend you boot to BIOS by tapping the F10 key on startup and check whether the issue persists in BIOS.

Also, I recommend you update the BIOS and the graphics card from the below link and check whether the issue is resolved.
