I downloaded the uno software. plugged it in, the computer cannot find the drivers. The set up info is for upto xp so it is different to windows 7. The computer does see a device but gives no detail.
Help greatly appreciated.

See section 4 of this page http://arduino.cc/en/Guide/Windows , it covers step by step for "Installing drivers for the Arduino Uno with Windows7, Vista, or XP".
