Sorry kid but you need a dedicated graphic card to run that game. GMA 3100 won't cut it. If you have a 9600GT atleast, it will run on low setting with a 2gb ram
YEES You can...First follow these steps:
1.Download/buy game
2.Download SwiftShader
3.See a tutorial
4.I think there is FPS Booster for GTA IV so you will get more FPS
GOOD BYE and have fun playing!!!
