For those of you lucky enough to own one of the newest nVidia based motherboards, be wary of
the latest WHQL driver set. The nForce 500 series chipsets seem to have many problems with the 91.31 video card drives and 9.16 chipset drivers, both of which are WHQL certified. The problems including crashing and data corruption, which is not only inconvenient but potentially harmful. While there may be other factors involved, the safe recommendation is to use the stable 84.21 driver set or the beta 91.33 drivers.
