I have a just installed Windows 3.0 on a Northgate 386. I am having a
problem that I am told is related to my video card, but before I replace
the card, I thought I would poll the net wisdom.
My video card is a Video 7 VGA-16 card running in 640 x 480 mode. When
I run windows applications in 386 enhanced mode, I get some "snow" in
the display. Everything seems to work fine
with DOS applications running in windows.
If I take my PC out of "turbo" mode and run it at 8 mHz, everything is
fine. If I rung windows in Real or Standard modes, everything is fine.
I have received the most recent version of the Video 7 drivers, and the
results are identical to what I experience with the standard VGA driver
supplied by Microsoft.
When I called Northgate Tech Support, we messed with all the dipswitches
on the video card, and removed all of the other hardware from the system
and their drivers from the Autoexec.bat and config.sys files to see if
there was some sort of contention. None was found.
So what do you think? Is there a problem with the video card, or can I
try something else to fix the problem?
Thanks in advance for your help.

I recently upgraded my video from EGA to VGA. The VGA board
is by Boca (called BasicVGA, 256K, with Chips F82C451C).
Also pertinent is the presence of a Western Digital
WD8013EBT ethernet card. My problem goes away if I take
this card out, but of course that's not useful in other
contexts. I'm not planning to use Windows 3 over this
network, so I installed Win3 with plain VGA video and no
network.
I suspect the video driver, since I don't have the problem
if I switch the video to monochrome VGA or Hercules (ugly!).
The problem looks like this. At arbitrary times, there's a
little pop and a flicker on the screen, the cursor is gone,
and the whole display goes to hell, either lots of vertical
bars or just out. With the bar mess, I can altF to get out;
with the blank screen, only a cold boot does it.
I poked around cica looking for something that might speak
to my problem, without success. I'm going to call Boca, but
if anyone has a suggestion, I'd be glad to hear it. After all,
how can I live without Solitaire? :-)
