So I'm not sure if my graphics card died or not. It hasn't showed any signs of aging or slow downs. I took out the HDMI and it stopped working suddenly. There is an output in terms of power, because the monitor recognises that there is a video but the video it's self is just black. I'm assuming the HDMI port is broke, but before I waste money on a display port cable, can somebody tell me if it's dead or not? The fans are still spinning and the LEDs are on BTW
