So, I've replaced the motherboard, CPU, and RAM in my computer. I've kept everything else the same: hard drive, PSU, video card, disc drives, etc. When I turn on the computer with everything plugged in, it all powers up, however the screen stays blank and the two DVD drives I have begin to make clicking noises. The lights on these drives stay lit and after about 5 seconds the computer powers down completely. When I remove everything and only have plugged in the hard drive, video card, and mobo, the computer powers down at about 3 seconds after the button is pressed. Here are my specs:

520W PSU
AMD 6000+
7800GT video card

The hard drive is the same one from my old computer, I was planning to format it once I got the computer up and running. Now, since my old Windows install is on that drive, could that be the reason why this is not booting up? It doesn't seem likely, but I'm throwing that out there anyway.
