How to enable a Display Adapter?

I recently had an ASUS r9 270x put into my system but it doesn't seem to be active. My system recognises the Driver but I don't see any slight difference in my machines performance.
Additionally, in applications that show my computers hardware show they Intel HD 4600 my system came with. The new adapter also came with GPU tweaker which shows the cards performance in real time, the GPU usage has never moved above 0.0% and the Memory moved once for a second to 8.3% and hasn't moved since.
The driver is enabled in device manager, and I tried disabling the Intel HD 4600 so the r9 270x would be the only active driver and my screen went black and lost signal. Like any computer would without any display adapter active, I used TeamViewer on my iPhone to connect to my computer and re-enable the driver.
Since I have had the driver installed I've also been getting an error when opening Photoshop that states "We have encountered an error with the graphic driver and have disabled driver enhancements".
I have photos of DxDiag and other things that could help.
As I can only upload 1 photo to the Question, here are some links to the other in an image hosting website (TinyPic.com) How to enable a Display Adapter - 1 (CC hardware detection) How to enable a Display Adapter - 1 - 1 (Device manager) How to enable a Display Adapter - 1 - 2 (Another DxDiag) How to enable a Display Adapter - 1 - 3 (GPU Twear usage moniter)How to enable a Display Adapter - 1 - 4

UPDATE - I changed the primary display adapter setting in the BIOS from IGPB to Auto

(Options were IGPB auto PCIE)

And now I have a constant black screen even after restarting my computer a few times. I can't do anything, nothing happens when turning my computer on.

Open the BIOS screen and make the PCIe slot, the graphics default.
