Whenever i plug in my Xbox 360 controller for Windows, the controller shows the 4 green lights and Windows gives an error sound, but when i plug in my PS3 controller that controller works fine. and yes, i have the drivers installed, it just doesn`t work, most of my games won`t work with PS3 controllers, only with Xbox Controllers and the mouse and keyboard, but some don`t have the button layout on the keyboard all that well(example: Sonic Adventure DX which has a setup screen that doesn`t work).
