After taking apart my old pc in cleaning it I put it back together but placed the power supply with a new one when I go to turn it on. And then everything starting the fan on the motherboard and the graphics card but nothing is on goes on to the monitor and I tested it before I took it apart and I believe all of the pieces are together.
 
Solution
There should be two plugs that plug into the motherboard from the power supply.

Also, check to make sure that you have the fan for the CPU plugged into CPUFan1 on the motherboard.
