how to solve this problem
Old problem on HP
They do not have a standard BIOS and it is not friendly with the original AMD drivers, try to clean the system from normal drivers using the Display Driver Uninstaller, and if it does not help, then look for a more serious utility,
Do as it is written here

Not all laptops allow drivers to be updated...
Especially if it's an Intel processor, on an NVidia chipset and with an AMD + Intel graphics card.
AMD laptops usually do not have such a problem, only laptop drivers need to be installed on them
