The game risk

I have an older game, The game risk, on cd rom and it seems to load up just fine. However when I go to play the game it seems to have an issue with the color and graphics and color management. I have tried to uninstall and re-install and it contnues to do the same action. I really like playing this game and was wondering on what to do next? Btw I have windows vista 7 and my pc is only about 3 months old. It is an hp pavilion, that I had purchased from staples.

Thanks guys for your help
