Pentium 4 may require auxiliary power connector from PSU to motherboard.....power supply in the pentium 3 may not have the connector or it's not plugged in..

Just see if you can find some sort of 4 pin thing that needs plugged in on the mobo.  If you cant find the 4 pin on the psu, then try to take the psu from the newer optiplex
