SimCityâĸ 4 – SimCity.com. Finally got this to work on an ASUS A7N8X-X motherboard by vI had the same problem. It was the nVidia sound driver. Loading the latest driver (the 5.10 unified) helped but still crashed every hour or so vs. every five minutes.
Finally solved by going to the Realtek.com.tw site and downloading the sound driver for the 650ALC and removing the nVidia sound driver.
