80% of the time i try join or make a game the game crashes to desktop

Howdy!

If the game works sometimes, this type of issue can often come down to a third-party software conflict. I recommend trying disabling your start-up programs to test running the game with no background software running at all following the steps Here, then restart the PC.

If the issue were to continue please post up a Dxdiag to Pastebin.com and post a link back here within code blocks.

Thank you!
