Untouched no power.

So I was putting together a mitx rig today to use as a nas. And at first I thought I may of bent a few pins on the mobo. But I decided to put everything together first and try it to see if I had a problem.

I put everything together and sure enough it POSTed fine.
I then took a break and had lunch.
When I came back The Computer wouldn't power up at all. Despite the fact I hadn't even touched it. I tried makeing sure everything was connected tight. I jumped the PSU, and it worked fine. Tried to short the power switch so its not my case button.
I'm worried my Motherboard pins might in fact be bent, but then wouldn't I still get power, and just have post issues/weird beaks from the speaker? and wouldn't that have prevented it from posting earlier?

Either way I am stuck. Would like some ideas before I attempt Motherboard surgery in case it is not the problem. Thanks. I will try to help other people in the mean time.

First reseat cables... you don't want to have surprises

Also SPECS help in some cases...

already tried multiple times...

Specs are

Biostar Hi-Fi B85N3D motherboard

Intel Pentium G3220 CPU

Corsair CX 430 PSU

Corsair XMS3 Ram or something like that 2x 4gb dims

Tried it with just one DIM of course

case is the Cooler master elite 120

No GPU.

UPDATE:
I have done pin surgery and the pins are now seemingly flush. However I still fail to boot.

so if you jump start the psu it works ?? if thats the cause i would think something on the MoBo is broken

Pins where bent? then just RMA...

Seems like this is what I am going to have to do. Thanks for the help
