when i try to open games such as call of duty or anything like that they automatically minimize after they are opened... when i try to click on the tab in the side bar to try to open it it opens and does the same thing again.... sometimes restarting windows works sometimes it doesnt fix it... all video drivers and games are up to date... ANY help appreciated,,,.. thanks all
