Ok so I have had my PC for about 6 months now and the Hdmi has been working fine when I connect it to my graphics port on my PC to my Hdmi port on my Samsung Tv. So yesterday, I was using my PC fine, as always and I turned it off to go to sleep. When I turn it on a again the Tv doesn't recognize the Hdmi any more and it just says "No Signal". So I re-booted and still nothing. I tried taking the cable out and back in, etc but still nothing. So then I plugged the Hdmi into my motherboard port and that works fine. Can somebody help me fix this please?
