The monitor of my pc with AMD Radeon RX 560 begins to fall out (freezes), usually just a blink, after I have been using (photoshop, lightroom) the pc for some time. This happens also in other applications. It blinks shortly, but, when it fails somewhat longer, I see picture of a white and blue monitor on the (not blue or black, but definitely dos like) screen. I think that maybe the graphics card, when getting warmer, fails. Somebody here knows what is going on? Thanks, Hans
