Major Logon Problems

Hello,
I am working on a gal's computer being as she can't get on the net and there
when you start the computer up was a message wanting her log on name and
password. When I put in her name it would take it but she said she didn't
have a password for it and that she would just click out of it and then the
windows would load but she was having all kinds of problems with it. Now
when I try and log on as her I click out of the log on area like her but
then the windows asks if I want to save the settings and I clicked no but
then windows will not load at all and when I click control/alt and delete a
task window comes up and there is nothing in there running at all as on the
desktop I can see. She is looking for her cd's or disks that she got with
it when she got it second hand but does anyone know whaat I should do after
she finds them? This is a 98 gateway computer if that helps ya out any.
Any help I would be grateful for.
Thanks,
Gidget
