Could this be the cause for not powering up at all?

Here are pictures of the possible problem

I bought the whole computer from an auction as broken or for parts. Everything else works fine, except this

As you can see, someone did a poor solder job on the EFI chip (or is it?) and I wonder if it could be the cause for the computer not to power up at all. Even the fan doesn't go on. Nothing. It's dead as a door nail

So how would I proceed? I guess analysing the board with a multimeter could show what's wrong with it, but I don't have a clue how would I do that + I don't have much skill doing repairs at a component level.

Thanks for any help!
