so what we should do to fix this
I am sorry but you cannot fix this. The gpu just lacks the support for this game.
what i have to do to play this game
You will have to replace your graphics card for one that support DX 10.1 or higher and has enough
performance for the game.
The ATI 3100 is a broken tinker toy of an IGP with terrible performance (it's also fairly long in the tooth). Intel's current HD series video chips are 4 to 5 times better without being good enough. Whether it had a limited Dx 10 capability or not is of no consequence whatever.
