Well, I have windows 7 ultimate 64-bit and i want to play halo, i have 4 gb of ram and nvidia 9800gtx+ graphics card. I also have it hooked up to a 52 inch lcd screen, and want to see halo one in full-screen glory. But when i open the game up, it gives me this tiny 15 by 11 inch box with the game going and black all around it. I installed the drivers for my graphics card. What do i do?
