Zoom in the screen, set the resolution to the lowest, and adjust all other graphics settings to the minimum as well. When playing, it's best to close other software to reduce CPU usage so the game can run faster. If that still doesn't work, it means the graphics card is not good enough. You can switch to a 256MB graphics card for $300-500, which is affordable. Your configuration is better than mine, and I can play very smoothly without any issues...
