Computer freezes when trying to start Radeon settings

Hi, I've installed an RX 470, disabled onboard graphics and installed 17.10.02. Installation went fine, no errors, restarted pc and tried to open radeon settings, got a black square appear, then pc froze

 

MB is msi FM2 A55M E33

cpu A8 5500

8Mb ram

fresh Win 7 sp1

 

I have also used DDU and retried, same result

 

Any thoughts ?
