Cannot install XBOX Controller on Windows OS

I bought a brand new wired Xbox 360 wired controller to use on my computer. I am using Windows 7 Home Premium. After installing the drivers, the controller was not working. I tried plugging it into other USB ports on my computer, but no luck. Sometimes I get a green light flickering on the controller, but only for a few seconds. I tried the controller on my Xbox, and it works fine. What could be the problem then?
