Recently i got an XFX Double Dissipation Edition R9 280x(Used), before installing it i used Display Driver Uninstaller to remove all traces of my nVidia drivers for my GeForce GTX 660. After that i installed the R9, booted my PC and absolutely nothing was displayed, the card and everything else but my keyboard and mouse was powered on. The card was connected through HDMI, when HDMI didn't work i tried VGA and DVI and neither displayed anything still. I have installed the card on one other PC and the same thing happened, nothing would display. I didn't really know of anything else to try so I've come here for help, I've never installed any graphics card since i 1st installed my 660. Any suggestion, ideas, or possible fixes are greatly appreciated.
