i recently bought the Civ IV game and installed it flawlessly but when i try to run it my computer crashes instantly and a blue STOP error screen shows up. The error message reads "A device driver attempting to corrupt the system has been caught. The faulty driver currently on the kernal stack must be replaced with a working version." The error code at the bottom is 0x000000c4. I tried uninstalling the game, updating my video drivers and havent had any luck. Some help would be greatly appreciated. P.S i have nvidia 64 mb geforce 4 mx 420, pentium 4,
