Hi
Compiz is a set of programs used for managing the desktop and enabling the
special effects. You use the Synaptic package manager to uninstall and
install them(and all your other software). If you do not know where that is
you find it in desktop menu under System>Administration>Synaptic Packager
Manager. This has a search utility and you can search for compiz and it will
list all the compiz packages on  your system. You right click on the package
to get the list of available actions. All I did was choose the complete
uninstall option(removes all settings as well as the software) and then
reinstall. It seems that that did the trick. When doing this I was logged in
using the Gnome failsafe desktop which does not need compiz.

Hope this helps. By the way, once you get used to linux you'll love it. I
took windows off my system 2 years ago and don't miss it at all. Have fun.
