First, this does not sound like a motherboard issue.

Have you taken and attached the monitor to another computer to
verify if it is working properly?   Also, have you checked to verify
that all the pins in the monitor's connection cable are straight?  If
a pin was bent over while reattaching the cable it can cause some
issues like this.

You should be able to use any off-the-shelf video card in
a Gateway system, as long as it has the proper bus connection,
(you will need to verify if the card is ISA or PCI).   You can pickup
an inexpensive Trident or Cirrus Logic card for under $15 to test
the system...  a basic 1mg card.

I would also verify that the system has loaded the proper driver for
your video card in the Device manager, located in the Sytem Icon
in your Control Panel.  (Start / Settings / Control Panel / System)
Win95 does not do change the drivers in the system very often...
although Win98 is notorious for it.

Finally, and I always hate to make this recommendation as it almost
always is not a factor, but be sure to check the system for a Virus...
I know...  usually Tech Support at Computer companies use this
ruse when they have no other answer...  but, in very rare cases
it can be a virus...  *wink*

Typically, STB cards are real stable and I have seen very few problems
with them.
