Radeon RX 570 ERROR 43

Hi all,

I bought myself a AMD Radeon MSI RX 570 4gb graphics card and hooked it up to my dell 755 using an external PSU and PCI-E Powered Riser card.

Once I install the drivers, and I have tried a few variations of the drivers I get:

Windows has stopped this device because it has reported problems. (Code 43)

I have tried uninstalling them using DDU and reinstalling, but same issue!

Please help!

Thank you
