To add to CriticalPoints suggestion. Go to Start/Run and type devmgmt.msc and press enter. In the Device Manager any devices with yellow marks need drivers installed. If you have a name brand computer (HP, Dell etc) go to the manufacturers support/download drivers site and type in your service tag # or make and model # to download any drivers you need. As Crit said, install the Chipset driver first. If you need help finding the drivers, on your next post include the make and model# of your computer.
