After i reformatted my computer, i sucessfully reinstalled all of my drivers, except the video drive, each time i try to install it i get an error message saying, "The system cannot detect the device, please confirm that the device is configured properly and then restart the setup program."

Where is the driver coming from? Are you 100% sure this is the driver that was installed before?
