How do I make my Gateway computer safe to return to manufacturer

No CD with later models of computers. I always have to make my own or order one. I usually order one. I am taking this computer back to the store for a replacement. The reason is, I bought this computer new in June, 2013. From the very beginning the keyboard malfunctioned. I called the manufacturer. They claim that it is a software issue not covered by warranty. I purchased an extended warranty when I purchased the computer. I was working on a manuscript. When you begin to type, the letters were out of order. The faster you type, the more jumbled it becomes. Then the page will completely disappear from the page. This is a new computer doing this. I did not install the software. Everything is installed with Norton antivirus and other Norton products these days. I finally sent it back to the manufacturer, which cost me $50.00. When it came back, it was still not working right, but was better. They claim they installed a new keyboard. I called them back, so they sent me to InTechnology. Another large fee was charged....still no luck. They removed all Norton products and replaced it with McAfee. The computer finally went down about 6 months ago. I was so upset that I put it back in the box and put it in the closet with my warranty and receipts for the repairs. I got it out recently, and was able to get it on, but the keyboard is a big joke. I spoke to a person who works for the company I bought it from. They will take it back and return my money or give me a new computer. Therefore, I prefer to remove anything such as programs, passwords, e-mail, and anything saved to protect myself. Nothing is safe out there in the world of modern technology, so why take a chance!! I make a mistake when I purchased this computer, because this manufacturer is not trustworthy!!
