AMD Gigabyte Windforce R9 280X & Monitor Problems

[Bananacheeze]

Hey guys! New to this forum.

I've got 2 different problems I think.

I just bought a entirely new PC, every single component is 1 day old. I built the PC yesterday and downloaded the games overnight. I realized that I wasn't getting the anticipated performance and soon enough I saw that it was because (I think) my R9 280X isn't detected.

I'm running Windows 8.1 and under Control Panel - Devices & Printers - Display Adapters- the only thing that is shown is the integrated graphics - which is the Intel Graphics HD 4600. That is the only thing showing, the R9 280X does not show.

How do I solve this?

2. My monitor is currently using a VGA Cable connected to the Motherboard. I tried using a DVI-DVI Cable connecting the Monitor to the Graphics Card, but as soon as I turn on the monitor, it says Digital Input - Entering Power Saving Mode.

Any help will be greatly appreciated

Thanks in advance

go into the bios and change the video card to pci

Would the BIOS be the EUFI or something DualBios?

eufi is a type of bios and dual bios means two bios

Thanks. I checked. It's the Gigabyte UEFI DualBios.

When I boot up the computer, there's huge amount of fan noise, and after 3-5 seconds it goes to an extremely quiet hum. I'm using a 550Watt Power Supply. Would that be the problem? (That it isn't enough)
