[Windows10, AMD A8-6600K] Screen flickers


I have a problem with my Windows 10 system and probalby the AMD A8-6660K APU with Readon 8570D without any additional graphic card on a ASUS F2A85M-Pro motherboard. The screen flickers and makes working very exhausting. I've tried the recommended fixes from:

1. I do not have any third party anit-virus program running, nor any apps that cause the problem. Also the flickering is visible while booting.

2. I updated to the newest driver (​, 15.7.1 WHQL). Previously unistalled the old driver and restarted.

3. I've uninstalled Realteak drivers, as I read in some forum that this might help. Do not remember where.

Can anybody recommend me a fix?

Thanks in advance,
