As someone said, PopCap games are a good choice, Peggle being the best one.
The Sims is a really love/really hate chance, I'd take Sims 2 to save money and if she gets addicted then Sims 3.
Portal is nice but I don't think is a for total beginners, but it sure is the best FPS for girls.
Music games are great, Guitar Hero is a good choice (but mind that the PC version sucks, at least GH3's). You can also get Ultrastar for free, is a PC version of Singstar that you can import Singstar's songs into.
Fable may be a good introduction to action RPGs too, you can get the first one really cheap.
