Hi,
I hope you have tried this driver version from the HP driver page. However if not, please install this version once:

If you still face the same issue, I would suggest you to remove the additional video card from the unit and try only with integrated card.
You could try this AMD card in some other unit and check. If you find issue with the card, get it replaced.
Reply with update!!
