If ur laptop is slow, use a pc that has internet connection n search 4 "acer aspire 3680 drivers" in google. iv also got the same laptop. i was able to download most of(if not all) the drivers from the acer website. u can also check other websites shown in google. choose the drivers you need according to your operating system. be attentively, because some drivers for Acer Aspire 3680 can be used only with one operating system! so since u hav vista loaded, ul hav to download drivers combatible with vista. u shud check the missing drivers by right-clicking on my computer, then click on hardware tab n then click device manager. devices with yellow question marks hav missn drivers. im not too sure how its dun in vista but i think it shud b simila 2 xp. also click this link or copy&paste in url space, n chek scroll-down menu. u shud find ur drivers thea. :)
