So I recently upgraded my computer and bought the xfx Radeon r9 280x and when I put everything in my computer it uses Intel graphics... It came with an installation disk but when I try to install the files nothing happens. The fans on the 280x spin but it's not enabled or something. Have I missed a step? I have an i3-3220 and a 650 watt power supply. If you need any more information just ask.
