do あなた use your pc alone?

I don't understand.
Do I only go on ファンポップ on my PC? If that's the question, than no. I also use my iPad and iPod Touch.

Like with no one else in my room? Uh... yes?

like am i the only user of my pc? if that is the 質問 - luckily, yes.

Yes, I own my laptop to myself :)

If あなた mean do I have a computer of my own yes I do.

Whatever of the above^ this 質問 means, the answer is yes!
