Start by checking your wall outlet, make sure power is there, Next are ou plugged into an outlet strip? make sure the outlet strip is still working. Then unplug/replug the power cable to the pc. If still no fan from power supply, yup replace powersupply.
You can look at the wattage once you remove it to get the same model number to power it back up again or now is the time to change cases if you don't like the setup of the one you have.
Good luck

To manually test a power supply, you need a voltmeter, and some electronics training.

It is just as easy to swap in a new power supply.

Voltage surges on the phone line can also cause the modem circuit to burn out, and prevent the motherboard from booting up.
