I double checked all my connections and power cables and it seemed to be tip top shape.  When I turn on the power supply the motherboard LED light comes on, so that is a plus.  However when I press the power button it does not turn the computer on, I.E. fans, CPU etc.

I even took out the video card and a stick of ram to see if that would show any different result and it did not.  Not sure where to go from here.

Any help would be great.

you sure you don't have any computer parts that may be DOA?

Some might be DOA but not sure which part it would be. 

EDIT: I know the power supply and the MB aren't because the LED light comes on.  Not sure about the processor, RAM or the MB.

wait, are you sure your MB is doing ok? You said you know the MB isn't problematic but you are not sure at the same time. Which is it?

Have you checked that all of the headers have been inserted into the mobo? Also the right way around? Sounds like that the Case Power Button and connection may have to looked at on the mobo? Do they correspond to the mobo booklet?

This is no indicator of whether or not the MBoard or the PSU is good or not...
It takes nothing literally to power an LED.

Remove the MBoard from the case...
Connect only the following:
PSU
CPU/Fan
Keyboard
Monitor
Vid card if needed
1 stick of RAM

The MBoard should be on a rubber mat or piece of cardboard.
