Good luck... BTW those eggs look smaller than the ones in Jurassic Park smiley-wink
Before you rule out power issues completely, consider whether the mains power you're getting is ok. I recall another troubleshooting thread where the eventual problem turned out to be a very old fridge. When the compressor kicked in, it caused all sorts of issues for the electronics plugged in on the same circuit.
I placed a 2200 µF capacitor parallel to the output of my power supply and voila. No more reboots for the last 4 days.
Add it from the 5V pin to one of the ground pins. If its too big a capacitor its conceivable the USB supply could trip out (more likely for an actual computer/laptop than a wall-wart supply).[BTW there is already 47uF on 5V rail on the standard Arduino]
