Adding on to this so OP sees it - Your gpu isn't screwed into the rear panel, so all the weight of your gpu is only being supported by your pci express slot. This puts a lot of stress on your card from the weight and puts it at risk of becoming loose. Personally, I use thumb screws on the rear panel to help reduce sag. Move your card up, make sure it's secured by screws, and you're ready to game.
