An unknown DirectX Error has occured [Crash]

Greetings. It would seem that I am being bamboozled. Whenever I try and connect to a game the following error message appears and the game subsequently crashes:

"An unknown DirectX error has occurred and League of Legends cannot start. Please make sure your video card is using the latest video drivers from the manufacturer."

Closing the error window in any way will simply prompt me to reconnect and experience this crash once more. I was able to locate a thread that had a similar issue however none of the fixes mentioned there have solved the problem. I have tripled checked that all of my Video Drivers are up to date. I have tried re installing the game after uninstalling, and the issue persists. Any assistance would be very appreciated.
