You want to get rid of everything? Don't just delete it. Make sure you either use the uninstall for the programs you don't need anymore, or use the control panel to uninstall programs. If it is folders you have created yourself then they are alright to just delete. You have to be very careful of some of the programs you just delete, because they can take a lot dll. files with them that are used by other important programs.

If you want to start of new, then the thing you will have to do is a reformat and install your operating system, and that is no easy task. You will lose everything that way.

I am not really sure what you are wanting though. When I had a different computer, I used to do a whole new format, and install of my operating system and just start over from scratch. No easy task.

If you have pictures on your computer, then you would have to back them up to a cd, or store them on another server.
