It depends on your system. If the OS came preinstalled then check the
documentation or contact the computer's tech support. The manufacturer has
to provide you with some means to restore the system. They have three
options:
1. XP Installation CD with a drivers CD. Most large OEMs don't do this
these days.
2. Recovery CD
3. Hidden partition on the hard drive with an image of the drive as
received from the factory. Sometimes this is in conjunction with a recovery
CD.
It might be a bit premature to do a system recovery. Normally that will be
destructive, loosing data and programs, so you have to start over,
installing the OS, reinstalling apps, and restoring data from a backup. You
do always have a full and complete backup, right?
Have you uninstalled that adaptor and driver?
