Hi! I've just bought a Ryzen 5 1400 to replace my A10 7860K, but randomly the system freeze then I have a black screen (1-2s) so system return to normality. That problem occurs usually when I'm playing or just surfing on internet. When I'm playing and it freezes+black screen, I can keep listen the game sound but I return to windows and game crashes. In windows log I have this message:

display driver amdkmdap stopped responding and has successfully recovered. After freeze+black screen, Radeon Settings crashes and I have to re-open it. I already tryed many things found in the internet to solve this problem but no lucky until now. I re-installed windows; re-installed video graphic driver, re-installed chipset driver, updated mobo bios, installed old video graphic driver and many other things. I really need help!
