I live for games. I have a copy of Doom 3, that was purchased about 5 months ago. I enjoyed it playing with it till my motherboard blew. I decided to switch from Accelerated Graphics Port(AGP) to Peripheral Component Interconnect Express(Pci-e). Now the problem is that it only works on ATI or NVIDIA graphics. I know very well that the onboard graphic can play it well, but when I install the game and try to play it gives me the error that display driver is not suitable. It is usually giving me problem with the Doom 3. Please help me with this. Thanks.
