making me wonder if the dell 3rd party crapware is countering the AMD drivers. how good is you power supply & what OS are you running. Sounds like a dricer conflict. Try load up drivers to your R5 first. Might be both drivers working against each other.
Unfortunately this didn't work.
Here's what I did:
Disabled auto driver updates
Uninstalled the RX560 and R5
Uninstalled the AMD settings in control panel
Deleted C:\AMD folder contents
Downloaded the exact APU driver for my system
Booted in safe mode and used DDU
Installed the APU drivers and rebooted
I still get error 43 in Device Manager and radeon settings won't open
Ok good news. I was able to successfully install the drivers by updating the BIOS with the Dell supplied update. The drivers I used were from the Dell website. Thanks for your help kingfish
