Drivers database?

Hi
Most of the time I do windows reinstallation of different brands’s computers, and I spend lot of time finding missing drivers speacily sound, VGS compatable, and network. even some time from the mafg does not work. It take me more time finding the driver then reinstalling windows. So if I go on-site for repair sometime there is no interent connection to download drivers. I was thinking to make a database from those divers which more used in system. I am looking for some tips, I don’t know how you guys deal with this kind of case?

Regards
