Deus Ex 2 Invisible War is quite strict abt System requirements.....
as u r using onboard graphics, i think it's either Intel Extreme Grpahics 1 or 2....
Deus Ex 2 requires some features like Pixel Shader 1.1 , which r not available in Onboard graphics.....

Also, try updating Graphics drivers, DirectX.....
