Avtoupravlenie in games

When he decided to play Grand Theft Auto 5,noticed a problem.When switching first person view and start to walk or run after letting the key walk(run),hero starts to run itself(automatically).Also this problem I noticed in other games.In Battlefield 3 the hero not only went but also mouse hovered in all directions.It's not quite nice and I don't know how to fix this problem,play on the laptop games.I think you help to solve this problem...
