A. Run the defragmentation program because it is the simplest fix to
try and often helps
B. Buy the new computer because every component will then be new
and improved, not only the hard drive.
C. Replace the hard drive with another one because that requires the
most technical expertise and therefore is the most likely ng to
help the problem
D. Buy the new computer because that is the most certain way to fix
the problem
