I have an HP Pavilion dv6-3123ez laptop and it has an HD 4250 and an HD 5470 in it. I had this exact problem a few months ago when I upgraded from Windows 7 to Windows 10. I also posted a thread here and it got resolved.
Around 8 months ago, I upgraded to Windows 10 and I noticed that the computer was kinda slow so I went to Device Manager and my 5470 wasn't working and was showing Code 43. I tried downloading and installing latest drivers from amd.com but the same thing happened. I tried a bunch of things like DDU and doing a clean install of the drivers and installing couple different driver versions through Device Manager but that gave me a different error that I couldn't fix. The thing that resolved it was installing the latest drivers, then uninstalling the display drivers through Device Manager and then downloading the drivers that HP provided on their website and installing the display drivers from that through Device Manager and that worked fine. Recently my HDD got corrupted and I needed to format it and install Windows 10 again and I got the same error 43 but when I went to HP's website to download HP's drivers, there were no driver downloads anymore, it just says that Windows should automatically download updates through Windows Update but since those drivers don't work, I don't know what to do, any ideas?
P.S. The 4250 isn't on the list of compatible GPUs for AMD's latest drivers but the 5470 is which is kinda weird since the 4250 works completely fine but the 5470 doesn't work at all...
