Well, well. Anniversary update and a pop up from AMD Quick Stream saying that a license for the software cannot be found. A few days of that (and me ignoring it) and now constant BSOD. AMD drivers issue for sure according to the error msg. After several attempts of trying to fix, by either rolling back to previous build (didn't work), restore to when it was working (didn't work), and even resetting my PC (didn't work, probably because I erased all traces of 7 on there). I tried a few other things and the only way it'll work without BSODing is in safe mode. On the plus side, I now know how to boot Win 10 in safe mode.
I'm downloading Fedora.
I'm sad about this, because I do like Win 10. Oh well.
