Troubleshoot my dead PC *fixed*

[HumanSymphony]

So a couple days ago my PC just dies :cryyy: Then I could not turn it back on. I push the power button and I get no fans, just nothing. The power supply is fine, tried it in another PC. Would this be a dead motherboard then?

EDIT: LOL WUT. My friend said to me "try holding the power button down for 30 secs" and low and behold, my PC booted up! interesting.
