If you have a relatively new computer, the chipset manufacturer (Intel) releases new chipset drivers to fix bugs and improve performance and compatibility. These are the individual drivers for the individual motherboard components you see in Windows Update. Usually it doesn't harm to update the chipset drivers, but there is no problem if you don't. If it works don't fix it, as they say. In fact in the old good days of Windows 95 & 98 updating the chipset drivers could lead to a BSOD because other drivers depended on these and malfunctioned with major changes.
