Problems and bugs are almost always related to compatibility issues. Start
with the compatibility wizard and run it on your present setup. If you
already have the XP CD, just place it in the drive, when the setup screen
appears, select "Check System Compatibility." If you don't have the CD, go
to the following site and download the upgrade advisor:

Do not overlook anything or consider anything it suggests as trivial or
minor as any such things can either stop the installation or be an issue
when installed after XP setup. Any firewalls, CD burning software,
antivirus and disk tools will have to be updated to the latest versions. Be
sure there are XP drivers for all your hardware, do not assume Win2K drivers
will work and have all such drivers already downloaded and available to you
before moving to XP.
Note that you may find updated drivers for your scanner but understand, the
original software bundle for that scanner is likely not to work or won't
install on XP even if an XP upgrade installation picked up the software and
that software will likely cause problems and crashing so use the drivers
only and dispense with the software.
You can check compatibility of some items at the following site but
understand, each system is different and you may have other items on your
setup that can cause conflicts:

All that said, you will most likely take a performance hit. XP is extremely
graphics intensive and you may not be satisfied with your system performance
after the upgrade.
