I have adesktop computer (selfbuilt). It's a great computer usally works perfectly.
But today I turned off my computer and it tool unusually long to shut down entierly but eventually it did.
After half an hour I wanted to play some games so I tried turning it on but nothing hapend. No fan, no lights, no nothing? What should I do?
I have tried Removing the power cable and wating for 15 min and then retrying. nothing.

Note: this has hapend before but it has fixed it self.

I'd flip the switch on the back of your power supply, or unplug the power cable and plug it back in, then try booting it back up first.
 
Do you have any LEDs visible on your motherboard? Most motherboard will have at least one indicating power is going to the motherboard. Did anything physical happen to the computer between when it shut off and got turned on? Maybe a heavy bump that could have knocked something loose? Power surge?

nothing At all.
 
Try disconnecting hdd data and power cable to see if system will turn on. Bad hardware will cause this. Also have you tried resetting cmos?
 
When you try to power up, does anything start to move? (ie. fans start spinning, led lights turn on or start flashing...etc.)
 
Hdd is the hard drive. Would have to remove both cables to test. Cmos is what the motherboard runs off of.

Try doing this. Unplug power from power supply, remove Cmos battery from motherboard, press and hold the power button on the case for 10 seconds then wait 10 minutes. Then reinsert battery and reconnect power and try booting up.

Did not work
 
Sounds like a bad motherboard. When you built it, did you use the standoffs between motherboard and case? You can try doing 1 more thing though.

Try building the pc outside of the case on a piece of cardboard to verify the motherboard isn't shorting out against the case.

When you removed power, you had to remove cmos battery that is on the motherboard before pressing power switch on case. Without doing diagnosing, we really can't help you.

1. Try a different power supply
2. Try removing ram modules and see if pc turns on.
3. Try building the pc outside of the case on a piece of cardboard to verify the motherboard isn't shorting out against the case.

What does the cmos look like
 
It's literally a battery on your motherboard.
