I just installed a new motherboard and video card. I went from a P3-1.2GHZ, to a P4-1.7GHZ. Also installed a new video card...from a Geforce2 MX/MX 400 32MB, to an Apollo 3D Thrill 315 128MB. When I try to access a game there is a box that appears and states: "Cannot find 640x480 video mode". I really need this mode in case it stops another program. How can I fix this issue? Thank you!
