If it's an OEM machine, like a Dell, HP, etc.. then you can use the factory recovery disks, if you have them. Anything else, you'll have to find the correct key or purchase a new key (or disk). Microsoft won't give you a new one with that story, although I suppose you could try to call them. You said the key is on the PC, so that leads me to believe that you can obtain or create recovery disks for your machine.
If you still have the old hard drive and can boot into windows, you can use software to retrieve the key such as magic jelly bean keyfinder.
Darn, beat me to it.
