Now it's 1 week of running with verifier and I encountered no bsods whatsoever. However, when I was playing DOOM the screen would turn black, music/sounds were still playing and I could still move/see the mouse cursor (after pressing CTRL+ALT+DEL or CTRL+SHIFT+ESC). ALT+F4, didn't work, too, so the only option was to reset the pc. This happened 3 times, I'm not sure if this is a DOOM-related problem, but I consider the system free of problems at this point.
I'm looking into replacing the razer synapse software, as the ability to change dpi or polling rate is quite helpful. I might send razer those minidumps, but I doubt they are able to fix their stuff.
You can mark this thread as solved, thanks for your help guys.
