I'm with GTW on this one - re-installing really is a sledgehammer solution for a problem that may well reappear as soon as you re-install the software / driver that is causing the problem.
I have one laptop that has been running the same installation of XP for just on 4 years now, without re-installing! And I do some serious work with it too!
I've had to re-install XP once on my home machine in 3.5 years. That was when the installable / demountable file system (CD, USB) decided to go AWOL and I simply couldn't fix it.
Fortunately I had a networked PC to hand to backup to.

PS - I recently chucked out the 5 1/4" floppies that Windows 3.0 came on, along with the Windows 3.1 and 3.11 diskettes! I also remember the early versions of DOS, at least as far back as DOS 3.0 & 4.0 - I recall the joy of EDIT appearing in DOS 5 so that EDLIN could be consigned to the BIN! Pun intended
