I have sony vaio with XP home preinstalled.

I'm having some problems with outlook 2000 and outlook express (both not responding when started up), so I'm thinking about a possible OS problem.

With the preinstalled XP home, I can only restore the the original factory setup and erase everything on my drive.

I want to know if I can get a new XP Home and run the repair function over the existing preinstalled version.
