Built new computer, monitor won't turn on

I have just built my first computer with new graphic card, ram, cpu, psu and mobo
Gigabyte GeForce GTX 760 2GB
MB ASRock 990FX Extreme3 AM3+ ATX
XFX PSU 650W 80+
DDR3 8GB PC 1866 CL9 G.Skill KIT

I assembled the computer without too much trouble and i connected it to the monitor, turned it on and everything worked fine.
Then I turned it off completely and the next day I turned it on, and now the monitor says "no signal" and shows a orange light instead of the green. My computer is running and I can hear the fans working.
What could be the problem?

Thanks in advance.

  1. open the case and see if the graphics card fan is spinning if not it is not properly inserted into the motherboard....also check to see if something is wrong with either your dvi/hdmi/vga cable and if it is plugged in porperly
  2. I opened the case and everything is spinning including the graphics card. I even tried to remove and re insert the graphics card with no luck.
    I have a HDMI to DVI cable and it seems to be plugged correctly in.
    I also tried to hook it up to my tv but it didn't work either.
  3. the graphics card output port which you are using is proberly bad.....is your tv hdmi? because from what i understand your monitor is dvi.....and i wld suppose your tv is hdmi...
