Help re-enabling graphic card

[tazaway]

So I disabled my onboard graphics card to put in my amd graphics card to hook up dual monitor. It worked, I then being an idiot disabled the amd graphics card. I have enabled and disabled my onboard intel graphics card and the monitor works fine. But when I try to use the amd graphics card nothing shows up on the monitor. What do I do? I took out cmos battery, doesnt seem to work, is there a way to reenable the amd gpu?

Take your GPU out of the Motherboard, boot up the pc, go in the BIOS and disable onboard graphics and enable the GPU, apply and shut down, put you GPU back in the motherboard. It then should be fine.
