If you guys can't help me, I give up and have no problem with letting it lay dead.

So I upgraded my old machine. I had an HP P7-1234.

I upgraded it entirely. Here are the parts.

So I put all of the parts together, and...no video at all. I set it up with only the new RAM. Nothing. Set it up with only the old RAM. Nothing. Removed all thermal paste and applied my own. Nothing. I got frustrated and even switched back to my old setup. I went back to the old case and everything. I had a Radeon HD 5570 installed in the old machine, so I tried both VGA and DVI on both the motherboard's onboard and on the card. Still nothing.

I'm seriously screwed here, so any advice would be great.
