Currently, I am trying to get my AMD Radeon R7 260X to work, but whenever I put it in the slot and then connect it to the PCIe power, it always gives me no signal. I know the graphics card works because the fan runs and nothing beeps. Currently, I have a crappy Nvidia GT 9800 running. Even when I have the Nvidia running and the AMD plugged in, I still get no signal, so I have to unplug the AMD from the PCIe plug. I've already installed the AMD graphics card drivers and it doesn't work. In the BIOS, I've already disabled the internal graphics card. I know I have enough power. Not sure if I should just give up or try again. I've tried with multiple monitors and nothing has worked. I've tried both my DVI and HDMI cords and neither of them will have the AMD work. Please help
