My computer recently got updated and now that i got it back when i try to play certain games like Diner Dash, Cake Mania, etc i get this message saying Video Card does not support this game.. So i then go under device manager to look next to Video controller it has a yellow question mark and a yellow exclamation mark over it. What do i do? Someone please help. Is there a website where i can go and download a video driver for free?
