Since last post, I've tried using two different Driver Locators, "Driver Agent" and "Driver Inspector." Both of them found several outdated drivers, but NEITHER one showed any indication of sound card drivers. Both showed results based on the Device Manager listings, but "Sound, Video and Game controllers" didn't even show up, whereas everything else in Device Manager showed up.
Can someone explain why this is? Shoot, I would have bought either of the Driver Locators, but why would if they can't even acknowledge the driver I need?
