For computers using built-in graphics chipsets, the game requires at least:

Intel Integrated Chipset, GMA X3000 or above. 2.6 GHz Pentium D CPU, or 1.8 GHz Core 2 Duo, or equivalent 0.5 GB additional RAM

my advice is to update your onboard chipset and see it that allows you to play the game..

if that doesnt work them youll have to buy a graphics card :)

if you can tell me what motherboard you have I can tell you what cards will fit in them ;)
