You should get yourself an external hard drive and transfer the stored data to it and then delete the data on your computer to free up space on your computers hard drive . You only have a 80 GB hard drive and the OS needs space to operate .You could consider a larger hard drive for your computer
XP Pro and loads of programs .. and MS Office ... 11 Gigs ish.
Years of stored docs, ghost image, and software .. 30 gigs
My DVD storage drive with 42 DVD's on it ... 120 gigs.
All depends on what you need to keep!
80 Gb is plenty for many people. Keep 30% free if poss.
