Is my motherboard dead? I turned on my computer this morning and I was getting no signal on my monitor. Holding down the power button wouldn't turn it off so I had to turn of the psu. Turned it back on and same issue, but I was able to use the power button to turn it off. Switched HDMI cables, same issue. Reseated the gpu (Sapphire 570), same issue. Reseated the ram, same issue. Put my old 2780 in, same issue. Plugged it into my tv, same issue. My motherboard (GA-970A-UD3P) doesn't have an onboard graphics card so I can't test that. I tried power cycling my monitor to no success either.
