Upper Mongogarie, trying to fix these bloody computers again

It’s weekend and I shouldn’t work but I’m working on my blog and some process are quite long. So during that time I’m trying to find out what’s wrong with these computers because they even don’t start.

I opened this alimentation and dust is everywhere. Maybe it makes a wrong connection.
No, even after cleaning everything nothing is working. These two alimentations should be changed, sorry…
