First turn off your iPod, and then turn it back on by holding down the power button and the home button together until the recovery screen is displayed (keep holding them down when the apple logo is displayed). Then plug the iPod into your computer, insure that you have iTunes open. A dialog box then should open giving you the options to either "Restore" or "Update", choose the "Restore" button. Please remember this WILL DELETE all data on the device.
