I want to return my laptop as I received.

I bought the Alienware 17 R4 on June 1st.
I've been using Macs for a few years now and I've been having a lot of problems because I'm using Windows.
Then I have a similar problem with Link as91.

My service tag for Alienware is .

I would like to return to status when I first got a pc like as91, can you help me?
