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.
