Nothing happens when I press the power button

[Lobotimizer]

Today I built my first computer i followed all of the instructions on a HAF 922 building demonstration. When I tested my motherboard and psu outside of my case everything worked fine. The fan on the PSU turned on and the motherboard LED did as well. Then i proceeded to put my motherboard in my case followed by CPU the ram then CPU heat-sink and finally the graphics card i plugged my CPU fan into the four pin connector. I then tested to see if everything wold turn on the CPU fan as well as everything else turned on. After the test i plugged in the rest of my components. When I did my final test the system was completely dead no fan or LEDs turn on.
Please help

A) you messed something up, backtrack and start over.

B) you messed something up and the motherboard got shocked/fried.

So either your mobo is dead (not likely) or you need to rebuild it and go through the tests again.

I have literally the exact same problem. My system booted the first time, I did cable management and close the case, then nothing turns on. No fans, no lights.

What was your solution? Was it the power supply?

start by paperclipping the psu. if it works then breadboard your system with just mobo, cpu and it's heatsink and pc speaker. If it still works start adding one by one the components until it doesn't work. If all works good on the breadboard, something is short-circuiting in your case.
MrPickle, follow suit.

Doesn't the paperclip method only show if the PSU works under nearly zero load? From what I've read it's probable that even with a successful paperclip test the mobo still won't power with a faulty PSU.

we will get there if the psu passes paperclip, because if it doesn't then your problem is right there.
