My bios, chipset, graphics card, and all my drivers are up-to-date. I have Uninstalled and reinstalled both hardware and drivers. It will work for awhile but then returns to the problem.

@bradensz,

We have done the basic troubleshooting as per the document and the notebook needs to checked taking remote access so that get to know it's a hardware or software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
