|"set up.....to log onto windows XP on the internet"|
Do you mean that when you started the computer it would go straight to the Internet rather than the desktop? If not let us know what it was doing.
"I tried to get back into the computer but now can't"
Please explain exactly what happens and how far you get.
The reason for the above questions is that starting a computer normally has nothing to do with the internet - it just goes to the desktop.
Always pop back and let us know the outcome - thanks
