OK, I was able to solve the problem by booting the system in safe mode and doing all of the above and using the amd application to uninstall the graphics drivers "amdcleanutility.exe". It can be downloaded from the official amd website.
You just need touninstall all drivers and software with DDU tool. Then Download Drivers from amd site . Then click on drivers- it will unpacking all to с:/AMD/.... When unpaking finish. and start instaling catalyst or adrenaline, you have to cancel it.!!!!! And go to device manager, find ur "GPU-Standard device" > properties> drivers> update drivers> browse> and choose с:/AMD/folder. And press install. After installing reboot and enjoy.)
