Is this a motherboard issue?

So, I have been putting together a rig for a little bit now, and am nearing completion (only need cpu). However, I have found while testing my computer that when I press the power button, it doesn't come on, unless I press it a bunch. I have tested the power supply, via paperclip test, and it passed. So I know that's not the issue. Is there anyway to test the motherboard itself for failure?

Really? Are you sure, because I can get it to stay on after pressing the power key a bunch. I'm not trying to boot the pc, just see if everything works so far.
