Hi Gary,
I understand that you are unable to enable the display adapters and if you enable it, you end up with black screen.
This is caused due to compatibility of the drivers or hardware.
You can try to uninstall the drivers for Intel and AMD from the device manager.
Refer to the below article to uninstall devices using device manager:

When the devices are uninstalled, reboot the computer and check.
Alternatively visit the display manufacturer website for updated drivers and install it on the computer.
For Intel based chipset :

For AMD based chipset:

Hope this helps, for further assistance please reply.
Hi Gary,
There is a giant problem with the Intel + AMD graphics cards which are in the range of the 5xxx and 6550m series (which is a rebrand of the 5xxx series).
These devices are still "supported" by AMD but a bug on the newest AMD drivers leads to a bootloop on Windows 8.1 and Windows 10.
This is a very serious issue.
Whilst I understand that some people will try to use the original HP drivers (As they should)
It still doesn't change the fact that a bug prevents a lot of laptops with PXAI (switchable AMD Intel graphic) configs from operating.
AMD seems to be at fault here.
Please check these threads for more information on configurations that are affected:
This issue leads to Windows Update installing drivers that put Windows 10 into Bootloop.

these issue is very serious and we hope MS can sort this out with AMD.
