I  have a dell 4600, I need to completely restore  it. and  I completely forgot how to do this.

My questions are:

1. Do i have to install windows XP or will it do it automatically

2. Could someone tell me the procedure and steps on doing this task, I dont want to pay Dell support to do this.

I have done this before, and i can understand the person that was helping me. So was a total lost of my money.

I can do it if someone would just tell me the steps.

    ie: what discs I need etc.
