Amdkmdap stopped responding and has successfully recovered


Apr 13, 2011
I need help! Since recently only, sometimes, when I play games, it freeze, causing a black screen for 5 seconds and finaly get back to normal with this message ``Display driver amdkmdap stopped responding and has successfully recovered``. It’s a homebuilt computer (assembled six month ago). I’ve monitored the temperatures, but everything seem normal... Also, it only happens when I connect to my monitor with via HDMI (it stop doing it with VGA). I’ve also tried to uninstall all the graphic drivers and to reinstall the new one (11.8), but the bug is still happening.
