Q: Login screen won't show up after "Starting Mac OS X..."

Hi all,

I have a little bit of a problem with an iBook that I was using a couple of months ago. (I haven't had time to use it since then...)

What happens is that I'll turn it on, and it'll start and everything, but a few seconds after "Starting Mac OS X..." disappears, the screen turns black and turns into a command prompt and asks me to log in through the prompt. After I log in, the screen just turns blue, basically like the "Starting Mac OS X..." screen, but without the window. Nothing happens after that.

Can anyone please tell me what's wrong? Can someone help me solve it?

Thanks in advance for any answers.
