PC not booting up
I just finished building my PC, but when I press the power button, absolutely nothing happens. I have made sure that the power supply is working (usually the main cause of the problem), but the computer still fails to boot up. What might be the other causes of the problem, and what are the solutions?
Thanks, Tom

Two other most common causes for this is:

1. You haven't plugged the case power button into the motherboard in the correct way -> consult motherboard manual
2. You haven't plugged all power connections from PSU into motherboard, or they aren't properly secured.

People have also freaked out over this, then it turned out they hadn't switched on the PSU power switch on the back.
