Case won't turn on.

[mamba238]

I have a Rosewill Black Hawk mid tower case....I build a pc yesterday and everything was fine, but the next day the case wouldn't turn on by pressing the button of the case....I repeat pressing the power button, then the pc turned on. Any Ideas what is the situation?

You may have grounded it inadvertently.

When you pressed the power before it turned on, did anything happen (fans spin once, flicker of lights, anything)?

If the components power on when bread-boxed, then that's definitely what you did.
