Because I don't like him.
Someone said it was a correct sentence. But I disagree. It is a dependent clause which can't stand alone.
But she knows nothing about him.

Why is this sentence correct?
It is a fragment, but that's not necessarily a bad thing in conversational English. Fragments are common:
What's that?
A pencil.
The answer "A pencil" is clearly not a "sentence", but it is an acceptable response to the question. Similarly
Why didn't you talk to him?
Because I don't like him.
That is an acceptable response. It is a correct fragment of a sentence, that works as part of a conversation. However, if you are writing an essay, you should avoid such fragments. These examples work because they are part of a dialogue. An essay is a monologue.
