I have had the same issue on two different laptops. Are you running windows 7? If so it was a driver issue for me. Go to device manager locate your video card and uninstall, remove all drivers. I like to use drive sweeper. Make sure Windows 7 has all updates installed. Once drivers are erased restart PC and let windows 7 install basic drivers and then load your latest non beta driver. Hope this helps. Worked for me on two laptops.
