In the 10 years since I have had a computer, I have had slow dial-up. I don't even think MSN offers high speed internet without making one partner up with another company. Unfortunately, however, I am a tech dunce. This is partly due to my learning disabilty, and partly due to my fear of being in computer limbo should I do it wrong. I am afraid of losing all computer use during a failed transition. My question is simply this: What are the steps required to switch over to high speed? Do I need to open the back of my tower and remove or add anything? Do I need to uninstall and install someting new? Do I need to replace cables? What do I need to do? I appreciate any input.
