|"I restored my factory image that came with my computer (its a dell)"|
You bought a new motherboard, therefore the Dell image & restoration disks are no longer usable or legal.
Due to the difference in hardware you can no longer use the Dell instalation, even if you managed to get it working, activation would fail, as it's tied to the Dell hardware.
The Dell software is not transferable to another machine, the new board makes it a new machine as far as the licence is concerned. Reusing the case does not make it a Dell.
You will now have to purchase a licenced Windows disk.
