1) Check the plug in the wall
2) Check the plug going into the machine.
3) Having failed in the last two, open the case (with the power off) and see if the main power line from the power supply is securely plugged in. It has to SNAP in completely.
4) Check to see if a fuse is available on the power supply and check that.
5) See if there is a breaker switch on the power supply that could have gotten turned off.
6) Check to see if the power is set properly (220? 110? ) for your little corner of the world.
If all of the other things fail, throw the power supply in the sack and take it back to the place that sold it to you.

Did you replace the power supply with one that was not from the computer's manufacturer? Use a PSU for an H.P. in an H.P. or Compaq, Gateway PSU in a Gateway, etc. Use the same wattage, unless you've added hardware that requires more watts. Do the math. Figure out the watts that you require and get that size of PSU.

If the power supply you replaced malfunctioned on your active computer, it could have damaged other electronic parts. Keep away from cheap or generic power supplies.
