I own a 3 year AMD computer, which comes with all the necessary stuff onboard (i.e. sound card, graphics card,etc).
Recently, I've been trying to use an AGP graphics card to replace the one onboard. I have no idea what the model of my motherboard is because I don't have any manual whatsoever of the desktop system. But on the motherboard, there's a sticker showing the graphics cards which are compatible with the motherboard. I've bought the graphics card recommended, Nvidia GeForce2 MX/MX 400 (I know, it's kinda old!). When I fitted it on the board, it is instantly recognized by the OS and after I have installed the necessary drivers, everything looks fine.
The problem starts when I tried to install games. One game I tried to install was NFS Underground and the other was FIFA 2002 (can't play the later editions also). For NFSU, after installing the game when I tried to run the game, it says that a graphics accelerator was not present and cannot proceed. As for FIFA 2002, there is a problem with a file named dx7, which I guess belongs to DirectX.
I'm not sure whether there is a problem with my motherboard or the graphics cards that I've been purchasing (I've got an FX5200 too). Please advice me on how to go about solving this problem as soon as possible........
