That is really weird, you should try Right Clicking on Dota2 in your Game Library, and clicking properties, and then Local File Tab and click Verify Game Integrity, it'll basically look for any corrupted files and see if you have any that prevents you from running the game properly. At least your friend can find a match right?

have you tryed to run your game in full-screen mode? In the past I used to have a lot of troubles with windowed mode.
