Hmmm... That's the first time I hear of a problem like that...
How much MB RAM do you have ? If you got less than 256 MB RAM that may be the problem. However, the game is still slow with 256 MB RAM. If you want the game to work smoothly, you'll need at least 512 MB RAM.
I'm not very up to date with 3D video cards, but I must admit I never heard about the one you have. If that's an "inboard" graphic card (included IN the mother board), that could also be the problem. Some "inboard" devices are not really famous and some games may not recognize them (it happened a couple of times with my sound card).
When it happened with my sound card, I went to the configuration screen (in the game) and tested each choices in the list one after the other... I ended up finding the good one... Sometimes it was "Sound Blaster 16", sometimes it was "Sound Blaster Pro" and it even happened that I had to select a sound card name I never heard of before. May be you could try the same thing with your graphic card.
