[Crash] Cannot play game

When i load up the game, it opens and i get a black screen that is in the upper left corner of my monitor and i can still see my desktop background. When i try to tab into the game it acts like i can do things in the menu but i cannot see anything and the game plays in the black screen, also when i tab back into the game the resolution stretches to fit my screen but the goes back to the black screen in the corner.



I don't know what is going on and I would really appreciate some help!
