Game Crash 2-3 min In

The game will play for 2-3 minutes then a window popup will occur and no popup will actually be there and the game freezes. It'll happen without the popup noise too. This has been happening for 3 patches for me, and others because I've been monitoring the boards. I cannot stand playing from behind and I love to play ranked but its impossible with this glitch. I'm going to drop the game soon at this rate.
