No, I *don't* jest.  I've been doing it for years.  A LOT of people use this
"quick fix" method to get the box to come back up.  It was standard
procedure in the old days.

I've tried it, *this* is also not a garanteed fixed.
The correct way is to open the thing up and thoroughly clean the motherboard
and all connectors.  I hear the board is extremely sensitive to static
buildup caused by the massive amount of dust the design inherently pulls
in.

One of these days, if I keep it, I'm going to get in there and solder all
the connections, including the devices on sockets (except memory, natch).
