You're absolutly right.  Any power supply connector that looks that
"fuzzy" is just bound to give problems! (If you haven't looked at the
.JPGs above, you won't get the joke...)

Ok, war-story time...

1: I was helping a friend upgrade his parents business computers (from old
286 to "new" 386-40's or 486-somethings).  Anyway, we took the cover off
one and the BIOS chip on the motherboard was completely black!  The area
directly over the silicon chip itself was melted and warped, and the
sticker on the chip was burned beyond recognition.  The system itself ran
fine, but if I hadn't seen it I would have thought the MB wouldn't even
POST...

2: A friends computer was acting funny after a lightning storm and the
CD-Rom had quit working.  We opened it up and saw that a *single* wire
down the middle of the ribbon cable going from the MB to the CD-Rom was
completely exposed.  Since the ribbon cable on either side was singed
severly, our only guess is that the path of least resistance to whatever
hi his machine went through the MB, the cable, and then out the CDRoms
grounding pin.  Very weird.
