I'm nowhereman from Belgium. Thanks for accepting me! Just started with electronics. Messing around a bit with motherboards. My 'new' secondhand motherboard got hit by the ground a think whilst in transport. And when I plugged it in some chips burned. The board didn't look like it would do that. Only the corner was hit so I thought it would be fine. I was wrong. But, because of that I wanted to learn about what went wrong.

Hi from your northern neighbor!

Looks like a lot worse than just a chip burning. Several layers of the PCB got melted. Perhaps a piece of metal got on a power rail and short circuited.

I would guess the power regulator failed spectacularly.
