PC won't turn on

[dunord]

There just seems to be 0 signs of power, fans won't run, LEDs won't turn on, PSU is switched on, no output from the monitor, nothing at all.

Before it won't turn on; I was using my PC like a normal human being but the power went out for the street and my PC just turned off. The power has come back and I tried pressing the power button. Nothing happened.

Motherboard: Asus Z87m-plus
PSU: My dad didn't show me what was my PSU so I don't really know what it is although I know it's from Corsair.

MERGED QUESTION
Question from dunord : "My Desktop won't boot up when the power went down"

My motherboard is a Asus Z87m-plus and when my power went off for the street usually windows computers go to sleep when things like that happened but mine won't boot up. My dad fixed this problem once and he discovered the desktop was on sleep although at the time he's abroad and I wanna try and fix it myself.

It looks like the PSU is gone.
I don't know how old you are, if you don't feel comfortable to handle that, may wait for your dad come back.
