:-/ Thanks guys. both of these comps belong to a friend and I said I'd do a favour and get them running right. Installing winxp is the first step. But of course he doesn't have any of the original drivers - ie for the installed sound and graphics cards etc - not worried about printers and stuff because as you say xp has most of these. i'm just worroied that I'm going to get stuck never getting his graphics and sound working after cleansweep instal.
