I have a old Hp Pavilion with windows 98 and its pretty much infested with spyware. I have 3 other computers with random things wrong with it. One with Xp Pro needs a windows repair for the registry ,One Needs a new graphics card and I have no idea what the other one needs but it does have xp too. Im pretty sure the hard drives are good in it tho.

Is there any way I could take the one of the hard drives from one of the other two computers and put it in my pavilion as the master hard drive
