HI. I am trying to setup my daughter's computer and it has win 98. after booting up it would display "an illegal function has been performed on explorer, it will be shutdown" (something like that). after clicking 'OK' nothing happens and no icons shows up even the taskbar, hitting win logo does not do anything. i am trying to boot it up from safe mode by pressing "F5". is it "F5" or "F8"? how can i fix this. thanks.
