The problem is terrifying unstable behaviour of my notebook that started several weeks before
Screen just freezing, so I'm not able to use my cursor only taps at built-in sensor display,
also my notebook wasn't able to switch between Radeon and Nvidia graphics correctly
AMD crash detecrtor periodically wrote my that "AMD software detected that a driver timeout has occured"
also tried to downgrade AMD Driver to 31.0.24033.1003 and even earlier - but nothing happened
Just after I disabled integrated graphics at Device Manager - notebook started work correct as I expected
but this drastically impacts battery life
