Hi, My questions is, can i use an xp home disc (with sp2 on it) with a computer that i intend to build when i have already used it on my main computer. The new computer i intend to build would have all new parts in it so mobo, ram, hddr, gfx card etc... Could i use my disc that i have already used on my other computer to set up and install on my 'intended' new build. Thanks a lot any help would be greatly appreciated. Thanks, john
