Unable to get OS to recognize passport

I have two Passports and I cannot get one PC to recognize it, my primary PC.  My vista based portable is not the problem.
Originally the primary PC recognized the Passport.  Later when I tried to hook it up, I got a screen that asked if I wanted to install software:  didn’t think I needed to so I said no and also checked the block that said do not show me this screen again(a mistake apparently).
Now when I try to hook it up, I just get clicking sounds from the drive(both do the same thing),
How can I get the OS to recognize the Passport?

If the drive is working on one computer and not on another, and you are NOT using a cable longer than 18", and you are not using a USB hub, then you are not getting enough power through the USB port on the one PC to spin the drive up.  You will need to purchase a power booster cable that plugs into two USB ports at the same time.   To get a power booster cable, you will need to contact tech support.
