I have an 8-bit 256K Paradise VGA card connected to a VGA monochrome
monitor.  It is used in an AT compatible.

One day while I was running explod, the fireworks screen blanker, the
screen started to waver and progressively got worse.  When I exited
to DOS, text was displayed fine.  Everytime I run a graphics program,
the screen would come up as if there is no sync signal.  If I turned off
both the computer and the monitor and turn it back on, the graphics would
improve (but still wavering) and progressively get much worse until
all I could see is a bunch of random moving dots.

Is the problem in the VGA card or monitor?  The puzzling thing is that
text displays fine, even in 50-line mode.  It's just the graphics that
does not work.  Another symptom is that when I run infoplus and checked
the monitor stats, the value I got for the amount of video RAM shows
192K, >800K, 0K, depending on how I got to the video page (i.e., PG-DN
from previous page, PG-UP from next page, or directly from the menu).

Any help and suggestions would be appreciated.

Thanks,
