I "clean sweep" upgraded from XP to 7 half a year ago. The dell website shows there are 24-ish drivers for my specific computer model that I lost in the upgrade. The thing is, I really havent had many problems running 7, and when I checked the drivers a lot of them apply to Window XP at the latest. so should I still download the drivers/some of the drivers (ex. since the upgrade I haven't been able to use my mousepad. would a driver on the Dell list make the mousepad usuable again)?
