Greetings!
A process essay will tell the reader how to do something, or explain how something is done. Therefore, pick a topic that describes a process with which you are familiar. You can't explain how to bake a loaf of bread if you've never done it! :-)
Think about your interests, hobbies, etc. Do you play the guitar? You could describe how to play chords; do you build model airplanes? know how to grill a great steak? download music online without acquiring too much spyware or breaking any laws? ;-))
I'd suggest making a list of things you know how to do reasonably well, then decide which one would be easiest to describe in a process essay. I'd be glad to help you with editing, once you get started.
Thanks,
