|Finding the drivers one by one isn't such a bad thing, what is it like 15 devices? A lot of the "driver scanners" are scams directed at people who know they need drivers but don't know how to make it happen, so they either fork out their hard earned, get infected with malware or both.|
You may want to find out who made you motherboard as you may find that they offer some sort of scanner for on board devices. If memory serves me correctly even nvidia have something along these lines these days. Most generic item don't get updates often, or ever depending on the manufacture.
If your really lazy and don't mind having drivers that aren't right on the edge then try microsoft/windows update in custom mode to see if their offering anything newer than you have. Most people might scoff at this but sometimes newer drivers for a generic item, like a conexant based modem for example, are hard to find elsewhere.
