i bought a computer that already had a os installed (win xp home)

1) and i wanna know how can i install win xp pro, cuz i tryed but a message saying the version of windows on the disc is older tht the version installed.

2) if i get a new video card put in, and for some reason i need to format my computer will it be reconized and automatically use the new card or will i have to  set it up?


thanks

p.s. and how can i find out if my current video card is a AGP GPU or PCI?
