I have a motherboard with dual P3 833 Mhz processors, 1024 MB ECC RAM, and for some reason a Geforce 4 MX 440 doesn't work on it. Everytime I use it, my computer's monitor just freezes after booting up. I have tryed several different Geforce 4 MX440s and they all did the same thing. Does anyone know what the problem is or if there is a graphics accelerator that is compatible with this system?
