POST 2 Short Beeps (Monitor NO SIGNAL) FIRST BUILD

Hello, when my computer turns on I get two short beeps from the POST, then the monitor says no signal and turns off. I also tried using my tv monitor and plugged the HDMI cable into the GPU. It still says no signal. I then did the thing where you just unplug the monitor and the power supply then hold the on button for a minute, then turn it on. Still no results. Lastly, I checked the RAM to see if that works using my other computer. It works. So the only problem I can see is the motherboard not working. All the fans, lights, hard drive and optical drive seem to be working.

PS I read the motherboard manual several times so I am assuming all of the plugs are in their place.
I also tried my other computer monitor.

    Why wouldn't I have a psu and ram?

    XFX Radeon HD 7850 1GB

    I'd say, at a real rough guess, that it's the video card. It may be fried for some reason. There may be not enough air flow space around it in the case and it has suffocated. Add a pic of your PC insides to validate. The video card uses nearly 300 watts of power at full load and averages about 265 watts, that is a lot of power and it would also give off a lot of heat.

    "Power Consumption Results: With the XFX Radeon HD 7850 1GB Core Edition video card install in the system our entire platform used 101 Watts at idle, which is on par with most cards today. At full load we hit 293 Watts in Furmark and in the games we averaged around 265 Watts. Not bad performance numbers from a mainstream gaming graphics card and it is right where we expected the power consumption to be!"

  4. According to the Specifications, there is supposed to be a 12v 8-pin connector but the site image does not actually have one on the motherboard, that I can see -

    Does your motherboard have the 12v 8-pin connector on the motherobard? Without it, you won't get use of the video out. It's usually located behind the VGA port on the motherboard but there is nothing but a wide open space...
