Replace tnt2 m64 with geforce2 mx-400

[pops49_49]

can this be done? I now have the tnt2 with 16mb and have a gforce2 mx-400 64mb. When I plugged in new card it would cause continual reboots to system. what am I missing? Won't stay up long enough to install new driver

try uninstalling the old drivers?
