having trouble restoring phone

http://androidforums.com – So I finally got my replacement nexus, and I've been trying in vain to restore my old one so I can send it back but I just cant make it happen. My computer (and another that I've tried to rule out the possibility of a faulty machine) won't recognize the device at all in either ADB or fastboot. I can't get USB to mount to try to put a backup on there to restore, I tried factory reset in recovery and now I have no OS (probably not a good idea now that I look back)... I'm all out of ideas, what can I do if I can't even get the computer to recognize the device? Does anyone have any elite tri (General)
