I was on my computer this morning checking my email and such, I was on for about 10min and then turned off my computer. Came back a little later tried to turn on my computer it powered on and made the normal noise and such and the screen stayed blank with the yellow indicator light on. I unplugged the hdmi cord and cleaned it and plugged it back in nothing, removed my graphics card and cleaned it and nothing. Found a DVI cord and a DVI to VGA adapter plugged it in, works fine anyone know the reason why it might do this?

well, there should be a built in option with your gpu driver. User display detect feature on your ati catalyst. So when the pc is on, disconnect the vga and connect the hdmi and see if it powers up. Tho my best guess is, the hdmi port is faulty on that gpu. Happened to me numerous times.
