I have a gateway e4100 desktop tower I need to restore it back to the firsttime I used it. I took made the three restore CDs and the one driver CD. How do I use them? Are there online directions how to use them? I was going back to a restore point on this computer running windows XP Pro when the power went out. Now it will not go to any restore points with out an error and the computer is not acting right. That is why I want to redo the system.
