OK...first of all, I'm an idiot.
  In an effort to speed things up with my system, I found a website that scanned my system.  It told me I should download a certain driver that would speed me up.  Guess it must have been a video driver, because now, everything is really small.  Fonts, icons, etc.
  I have messed around in the "display" area of control panel, but nothing will bring me back to where I was before this download.  Have also tried "system restore", but that comes back as INCOMPLETE, after trying several different dates.
  My next option would be to re-install Windows XP, but the disc that came with my computer says that I am running a newer version.  Not sure if I want to re-load that anyway, because I don't know what I would lose in the process.
  Again, I am running XP, SERVICE PACK 2.    Am I fighting a lost cause, and forever living in a world of tiny fonts and icons?   Thanks!Can you post, what WEB site it was?  Wish I could remember...sorry.In Device MANAGER what is listed as your Display Adapter?
