ANother thing is that I have a bundle of wire from the case that are marked TPA(+),TPA (-), TBP (+), TPB (-), VP, VG,
Dont worry about those bundle of wires. That's for firewire or something along those lines that's probably in the front panel of your computer, so it's not necessary to have it hooked up.
Take EVERYTHING off the motherboard and just leave in the CPU for now. just have power going to the motherboard and of course the wires from the front panel to actually send the Power to turn on the motherboard and see if you get any kind of response. If you don't get any beeps (of course make sure you indeed did plug in your PC Speaker ) then you know it's gotta either be the CPU or the motherboard at that point. If you get beeps, then start plugging stuff in starting with the RAM....if you plug in the RAM and you get beeps, then the RAM is good and you need to put in the video card, once you've put in the video card if you still get a black screen then the Video Card is causing the problems in that scenario.
Did you make sure to Clear the CMOS first before installing all those parts so that the BIOS didn't try to apply settings from a previous setup which you indeed do not want to happen.
