I have a RX560 and for the past 2 or 3 months my computer just repetitively crashes I would sometimes login my computer and my computer would just black screen the computer was still on my nothing was responding. I have tired uninstalling the drivers wi the ddu and the amd cleaning tool and both of them have not worked I tried installing and older driver and that also didnt work the only way my computer stays on is if it is in safe mode or if i dont have a driver installed at all.
Not much anyone can suggest without you supplying the 'Info........' Sticky (when you sign up/read).
Best thing i would suggest is taking it to an expert!
