I have an HP 500-227 desktop running windows 10 Home ( build 10240) with an I7 CPU, 12 Gb mem, Intel HD graphics 4600 (on motherboard)
Installed AMD catalyst 2015.0821.2209.38003. Loaded the latest drivers.
When I install a Radeon HD 6450 card. the system boots up with nothing on the screen.
When I try to get Windows 10 to recognize the additional hardware it does not see it. If I remove the card, and reboot, the system come up on the display.
At a loss here.
