Built PC wont start up - have I damaged my motherboard?

Hi folks!

I've decided the final step in several years of upgrading my PC - replacing the motherboard. I've plugged everything in and the board remains dead - no lights even appear down at the power and reset buttons at the bottom.

The full story is that - in my ignorance and lack of prep - I first installed the mobo without any riser screws. The board would start up, run for a second, and then shut down after a short. This happened about 4 times until I looked up the error and realized I was being an idiot.

I inserted the riser screws and then reattached the motherboard. Plugged everything in - inert as inert can be. Then I checked the board. Again, foolishly, I had misplaced a riser screw in the case, and I assume that this too was causing a short. But upon fixing the error and double (triple, quadruple) checking, I attempted a power on and nothing happened. not a half start, not a 2 second attempt at life. I might as well have been prodding at a stone.

I'm well aware I could have screwed up the mobo with those four original shorts, but I saw no flash, smelt no burn, heard no spark - in short, I had no sign that I had been overwhelmingly a moron. But the darn thing wont start up, and I'm totally puzzled as to what the problem might be. Considering calling in a professional.

Any guidance for a poor #buildapc noob?

Thanks!

Derek

Try unplugging the power cable, even if your PSU has an on/off switch, and let it sit for a few seconds to fully discharge, then plug it back in and turn it on. Then press the power button on the case. If all is well, things should light up.

Also, check your CMOS battery. If it is not seated correctly, it can cause this to happen, as well.
