**Important**
The Intel Chipset Software Installation Utility provides _functionality_ for AGP and USB, _not_ AGP or USB drivers. DO NOT DOWNLOAD THIS UTILITY IF YOUR DEVICE MANUFACTURER IS RECOMMENDING IT TO CORRECT AN "AGP DRIVER," "AGP GART," OR "USB DRIVER" ISSUE; IT WILL NOT CORRECT YOUR ISSUE.
Hmm maybe you should take a look at the motherboard manufacturer homepage and serach for drivers there.
