>when the machine is cold...causes Windows to lose vertical sync

 I recently bought a Gateway 2000 386/25MHz machine, and I have similar
problems with Windows as you have.  Rather, I have had the sync problem
(I'll check tonight for the diagonal line problem with vuimg).  I have found
with with 800x600x16, 800x600x256,1024x768x16,1024x768x256 modes.

I recently became suspicious of the monitor, when I noticed that pushing
lightly on the cable connector could cause:  (1) lose of all red colours;
(2) lose of sync.  First, I thougt it was the card, so I took the card out,
and put it back making sure everything was tight.  No change.  So, I opened
up the monitor connector.

On opening, one wire immediately poped out. It was a yellow wire, but
otherwise unmarked. I checked the pin assignments, and the pin missing a
wire was pin 14, (surprise, surprise) the vertical sync pin. The wire
connected to pin 13 (horizontal sync) also popped out while I was looking
at the connector (without much force, etc. being applied). I got out the
trusty soldering iron, and put things back together. This cured the sync
problem, but I still have the problem that pressure on the connector will
cause lose of red colours.

I'm tempted to send the monitor back, but don't want to be machineless for
any considerable length of time.
