Here’s one of these projects you have laying around for ages and keep thinking “I’ll get to it one day”. That day has come for this little unassuming beige tower. While it might look like a cheap boring PC tower from the mid 90s, this is actually a Macintosh clone from 1997 (as old as me, coincidentally).
This system is filthy and does not power on correctly, fans and hard drives spin up but no chime, no video, and no other signs of life. First thing I’m going to do is strip it down to individual bits and clean everything up nicely. The number of times just taking things apart, reseating them and putting them back together has fixed old PCs for me is pretty high, so that’s the first step. If we still have no joy, I will diagnose from there. I’ll also be checking out the PSU before reassembly.
