Repeated crashes

Yesterday I had a crash at the start of a game but managed to relaunch from and got back in time to finish the game. Today I crashed 6 times just trying to start a game so got to play no games at all.

It gives me a Core out of memory message. I never had this problem before the last patch. Any solutions?

I played the game almost every game since launch except for a few times when my internet was down. That streak ended today.
