Bad Power Supply?
So I boldly cleaned my pc. It was so dusty I took it apart and cleaned each piece by itself. I put it back it and it didn't start. I borrowed a working one from a friend to check what was not working. I put his mobo and cpu into my box and it didn't work. I put it back into his box with my cards and drives and it worked. So now I think the power supply is bad. But it does power up all the lights, the mobo LED display, the drives are spinning, the fans are spinning. Is it possible just part of it doesn't work?
So I put it in a new box with a new power supply and it didn't work with the LAN card in there. I noticed a few pins are black. hmmmmm I'll probably try that old power supply later on again with my stuff. I didn't know a bad LAN card can make your pc not boot.

Camero, any of the boards can cause the machine not to boot.
I have seen bad Lan cards, bad sound cards, bad modems, etc. cause a machine not to boot. In searching out those things, I generally start with just motherboard, memory, and video card. If all works, then start adding cards one at a time and check boot. Usually you can narrow it down pretty quick.
As far as the power supply, a quick check with a multimeter will tell you the PS status quickly.
