HI Anderson ,
Welcome to sevenforums
First of all you should have buyed XBOX 360 Windows controller for PC . This is the default controller which every PC game (which accept gamepad controller) accept it.
Controller's other then this are only detected by FIFA games , to my experience and they fail to detect in any other games.
What you can try is using Xpadder which simulates the keyboard and mouse using your gamepad.
Here's the link you can download that program - Xpadder.com
You need to download the game profile you want to use from there forum section and open it in Xpadder.
For more details on using it you can browse there forums.
Hope it helps.
