No display after reboot.

Two days ago my pc was working perfectly fine but suddenly it hanged and when I restarted it, there was no display on my samsung hd lcd tv. It shows a black screen and the tv says no signal. My gpu is sapphire amd radeon hd 6670 and I use an hdmi cable. I have cheked the cable, it is working perfectly fine, so please help me.

does your tv support VGA i would certainly try that first. and see whether your graphics card is actually still in working order, if you get no picture i would also try plugging it into the onboard graphics through VGA and attempting that.

I have tried evry port, there is no display, even the motherboard port is not sending any display.
