i had read posts about people getting these random freezes.. never happened to me until last week. I had one account that would freeze, at random. I had not knowingly changed any settings, so I was clueless. I did everything recommended, but ignored DX11/9 stuff because i KNEW i had it set to DX11. Well i would have saved a lot of time.. that one account had been switched to DX9 somehow... put it back to DX11 and no more issues 8)
