I have been playing Grand Theft Auto IV for some months now. It was running smoothly but now its getting a bit irritating to play the game. The problem is whenever I try to enter my car and is inside the car I see smoke coming out of the car and then suddenly the car starts accelerating automatically on the streets. Even if I apply breaks it doesnít stop and crashes down. Also, another issue is many of the times Niko staggers like when he does when he staggers even if he did not drink anything. Itís really irritating, how do I solve this? It will make my gameplay less exhausting. Please help me.
