Video failure

Question

I believe my K7VM4 to be failing due to age.
After a while running the display will disappear, but I can tell that everything else inside the box is running. Have swapped display adapters (nVidia FX5200) but result is the same.
Do you have a recommended or suggested "drop-in" replacement? for this micro ATX board. I have read that the K7S41GX is good. I really don't want to have to change components and spend hours (days) configuring.
Thanks
