Depending on what you want to do, using a computer is relatively easy. First press the power button on the computer case and do the same for the monitor. Wait for the computer to load fully. This may take a few minutes depending on how slow or fast the computer you are using is. Once the desktop has loaded, you can click on the icon that fits what you want to do. If you want to write a letter and mail it to your dear Aunt Sally, double click on Microsoft Word or if you want to send her an email, click on the internet icon. If you are going to send an email you will want to make an email address for yourself which you can do at AOL, Yahoo, or MSN.
