Just saying as when you got a new mobo, it would have been a different MAC address, and to "refresh" it a power down is required.

This will be the issue.
Your router will have cloned the mac address from your old network card and so your router and pc would have had the same mac address, that'd allow you to switch the cable between the two of them freely without power cycling the modem.
Now you have a new network card you have a different mac on your pc so the modem doesn't recognise it and you wont get an ip address as your dhcp lease is for the old mac address. You'll have to power cycle the modem for it to pick up the new mac address and that'll get a new dhcp lease for it.
If you want to switch the modem between the pc and router again then you'll also have to go into the router settings and clone your pc's mac address again.
