How about a quick rundown (inventory) of the machine, the OS in use, how many years old are the drivers and more.
Be aware that some older cards never had the drivers updated to deal with Windows 98, IE 5.5 or such.
Try another PCI Video card that has drivers after 1999.

I have a 4 MB PCI cyrix logic video card which only functions at 16 colors--not even at 256 colors--and when I try to set it any higher, the PC causes a windows protection error or just shuts down on reboot. What could the problem be? I have the correct drivers.
