I notice that your SysInfo shows two display adapters, and that one of them has MS Basic Driver which is never meant to be used for any more than a placeholder until a decent driver is found. Is this the AMD device shown on the HP Downloads page for your Serial here: https://support.hp.com/us-en/drivers/selfservic... ?
Doe the notebook actually have dual graphics?
If necessary you can trace the device make/model using it's Hardware ID as shown here: http://answers.microsoft.com/en-us/windows/wiki...
Did you also try the older drivers stored in the Device manager for Display device, which was one of the steps I gave above. The driver which actually worked should be stored there unless it was wiped out. Go there now to try all previous drivers.
It's important to try all steps I gave again to try to find a good driver. What does the AMD Autodetect find?
