Getting this old thing working again

[Optimuze]

Been bored lately and figured I could use some practice before I build a new computer. I had an old Gateway GT 5670 PC sitting around that wouldn't show anything when connected to a monitor. I tinkered around with it for a bit, then I put a HD4550 GPU in it, 3GB RAM, bigger fan in back, and a 200GB hdd that I know works from another old PC. I also have a CoolerMaster CPU Cooler I can install as well. Well, I still can't get anything to show up when I plug it in, either HDMI or DVI. I have tried using one hdd at a time or both, neither works. I can hear the thing powering on, fan is spinning, but no picture. Anyone have any ideas? Is my motherboard just dead? I am not really sure what motherboard actually came with this PC either. Like I said, it didn't work before I started tinkering, didn't ever work since I have had it, I got two old broken PCs from my dad a while back so I could play around with them. Got one to work, but its even older than this one so it is real slow, and I would like to get this one working too.

I know its ugly in there, just trying to get things working first. I can always take more/better pics if needed.Label 1 / Label 2 / Label 3 / Inside 1 / Inside 2 / Inside 3 / Inside 4 / Inside 5 / Inside 6 / Inside 7.

The processor isn't installed into the motherboard. You can clearly tell from the pictures. <.<

Wow, didn't even notice it stuck to the heatsink when I took that off to take pictures/clean, now, assuming it has the processor back on like it did before(when I was trying things out), any opinions?

So, no one here can actually help, just offer jackassery "Like a Boss"?

A Mod might as well delete this thread, I'll take my questions somewhere they can get answered.
