So I bought new PC and it started to bluescreen once or twice, I asked in microsoft forums and someone told me to update my graphic drivers.
After I updated it yesterday, it started bluescreen more. I got three BSOD today. Now I'm almost sure that display driver is the main suspect.
I downloaded Radeon Crimson 16.7.3 by the way.
