Sorry to respond so late but I was kind of out of town. If no light comes up your NIC is definitely kaputt (defective in english ;D).
In your case I would pull up the device manager and remove the network card (uninstall) and delete all the drivers for it. Then turn PC off and replace the NIC , reinstalling the new drivers...

Otherwise you will have orphaned drivers on your PC which can, if too many, slow down your PC
