Keyboard Problems

[diskwizz]

Hi I am new here and have joined because of a specific problem.
I am fixing a laptop for a friend. It needed a complete format etc.
The laptop is a Targa Xp-210
Once i had reinstalled windows Xp I had the following problems
When I hit 0(zero) i got the * and when i hit i we got a 5. So basically it is looking like the Fn key has taken over the main role. DOes anybody know how I stop it from doing this?
Many Thanks in advance DW.

Have you loaded all its native drivers yet?

[diskwizz]

NO, this is how I discovered the problem. Was just about to jump online and the first driver I was going for was Audio.
Thanks
