Can't get my new pc to post

[HaloReach 2]

A friend of mine convinced me to build a pc instead of buying one my only issue with building a pc was that I had never done it before. We put it all together but it wouldn't post we called Support and they told us to take out the ram the Graphics card, We did that and got nothing it still wouldn't post. That was last Tuesday I did some research online the next day a found a thread saying we missed a 12v plug on the Motherboard I put it together today and plugged everything still wouldn't post. Al the fans Work. my Graphics card wouldn't turn on as well. Because it won't I haven't been able to install the OS. Any help would be appreciated.
