I am having a problem with my new setup. Have been using Ryzen 7 3700x paired with GTX 1080 for over an year with no problems. Now I bought new R6800XT and here problems started. In general during heavy load (gaming) 3d Mark (espeially Time SPy CPU test) my computer crashes into black screen and there is no other way to restart than turning off a power supply. Temperatures look ok - no OC beside standard boost CPU profile and XMP set with two clicks in bios. Any Ideas?

all drivers up to date
Did you COMPLETELY cleaned your old Nvidia driver from Win10?
either do a fresh install of windows (i would highly recommend that) OR use "DDU" in "safe-mode" (requires reboot) and clean both drivers - than reboot again and install latest AMD driver
