Have an emachine that I need to make sure it is the power switch going. It has black and white to pins on the motherboard. Out of the machine parts I have I cannot find a switch that only has two pins. Is there a way to mimic however the switch works to see if the machine will turn on? I know power is good to the board with new power supply the green lights up and sometimes when I engage power cord the cpu fan spins slightly like its got a charge.

Look at the diagram below

 Intel pins
You should find a similar set of pins on your motherboard.  Most boards follow the Intel spec which is the diagram above.

Find pins 6 and 8.  In the diagram they are the ones in red.  You should be able to remove the cables from the pins on your board and short the two pins with a screwdriver.  Just touch it briefly.  That will either turn the board on or off.  If that doesn't work then your board is faulty.

Assuming everything is disconnected (cables) and all cards removed from board and the problem still persists then the CPU would be the next item to look at.

Was the second motherboard known to be working?

And also try the test with the motherboard outside the case but resting on a piece of cardboard.  You should be able to run the cables from the PSU to the board OK.

already tried the new mb sittingo n antistatic bag on table and no dice. When I purchased the 2nd board I was told it was tested with a short 2 week warranty.

Then you are probably going to have to get another CPU then.

I'm presuming the second PSU is known to be good and the second MB is good also.
