4. A girl called Felicity called you as a service referral. She has reported that (in her computer)
the date of the system goes back 5 years every time she turns on the computer. No matter
how many times she sets it back to the right date the issue remains. What is likely the cause
of her problem? What could you ask her to do to fix the problem? In case there is something
to be purchased, what would she ask for?
