Trying to teach myself how to do things for myself. I have installed a new hard drive in my dell computer. I have the operating system cd as well as the driver and utilities cd which came with the computer. Here are my questions: 1. Do I have to format the drive before I install the OS or drivers? 2. Which do I install first - the OS or the drivers? I am fixing this computer for my mother and unfortunately she only as dial up. After I add the modem is there anything else I need to do to "activate" so that it works? Thank you in advance for your help.
