Password for updating iMac 2005 cannot be found
I came home to visit my parents for a few days and both of my parents are having trouble remembering their password to update their iMac circa 2005. I have been trying all the passwords that my mom would use since they involve some aspect of my name. However, I have been fruitless in this effort.
What other suggestions are there to be able to update the apps on their iMac because it is slow as molasses?
What makes things worse, is that my mom no longer has access to the email address she had on file when she first set up this computer.
HELP!

iMac, Mac OS X (10.5.8), circa 2005
