How to copy songs from your iPod to your PC....not working this time

I have read and used your article, How to copy songs from your iPod to your PC, in the past and it has worked great for me. However, my computer recently crashed and now we own a used computer. I'm trying to use this same technique to transfer my iPod music to my 'new' computer, but I can't locate the Portable Media Device in the control panel. I've looked other places, but can't find it. Any ideas why I can't find it? Your help would be greatly appreciated!

Thanks,

Maddie
