Crash at least once per game

I don't know what is causing it, but I crash at least once per game. It's so consistent that when I see any sort of lag or there's a sound that doesn't coincide with what should be happening I know it's about to splat. I've tried to not have anything running in the background like chrome or playing it with only one screen active (dual monitor), but nothing seems to stop it from splatting on me. I've lost multiple matches (cause I'm bad) and I'll have an item that I need to put on someone or rearrange the board, and have to wait the couple minutes to reconnect only to find my screen grayed out.
