DIRectX error

JUst lost the last of my lp because of random "Unkown DirectX Error". I cant even play the game without some error that will gurantee I lose lp everytime it occurs, no matter how often I update my driver. I Updated it literally 2 days ago when I got the error the first time, I played last night fine. First game I try to play today gives me an error. Can Riot please find a way to detect if people have system issues like this so they don't get penalized. It seems extremely unfair to lose lp over something unforeseen and out of my control. This is one of those things that just really makes this game so unenjoyable sometimes.
