I have the nvidia gf4 ti 46oo with an AMD 1.9 and running winXP. I have the 28.32 patch from nvidia and the civ III patch for xp. I got the game to play for about a week or so, now nothing. All it does is crash the system, and the computer tells me its the video card causing the problem, but I'm not sure if thats it or not. Has anyone else had this problem, and do you know of anything I could try to fix this? Geez, I thought I built a lean mean gaming machine, but so far I'm disappointed. Is it xp or the nvidia to blame? Any help would be greatly appreciated.
