New build boot problems

[Synon29]

I can't get my new build to boot up. I started unhooking things when it wouldn't boot and i've found that if I have ANYTHING plugged into the connectors that are not hard wired into the power supply the computer won't boot up. As soon as I unplug the power on the hard drive, and graphics card the computer will boot up again. I've tried them both seperately with the same result. I've also tried them in my other computer and verified that they both work. My thoughts are that something must be wrong with the power supply itself. I'm using a 700w ocz power supply, asus p6t deluxe v2, core i7920, 6 gigs of ddr3 ram, western digital 1 tb caviar black, and a gtx 285 graphics card. Anyone have any ideas.

Start from the beginning. Do a minimal install outside of the box with one stick of ram and the GPU. Make sure the one stick of ram is in the right slot for that configuration. Check the case connectors, specifically the power connector, for the correct orientation to pin one. Do not rely on the cable label. If it boots, add the HDD. If no joy, try another stick of ram.
