There are several things that will cause this. If its the PSU its easy 
to check, remove the power connector from the mother_board. You will see 
that there is a green wire in that harness. This is the line that is 
brought to ground to start the PSU. short the green wire to any black 
wire and see if that turns on the psu(fan will turn on) If the psu turns 
on then the most likely candidate is you cmos battery. if the psu 
doesn't turn on then of course its your psu,
