Uninstall Office 2003

From a newbie: (If this has been addressed elsewhere, I apologize.)

I want to uninstall MS Office 2003 and remove all traces of it. Add/Remove
will not allow it. The program has been acting up and producing error
screens/cannot access/shortcut invalid/ and generally being a pain. I have
the CD but it won't even let me reinstall.
How do I remove this program from C drive so I can use the CD for a new
install?
The present install has been in for a year and has all the updates/security
patches/and whatever else MS considered necessary. I just went along with
them and installed. I installed security patches which have no 'uninstall',
and until I can get rid of the updates/patches, the program itself will not uninstall.
In add/remove, I tried to remove/change updates, but it won't budge.
For sure I need help. A reformat is not something I'm looking forward to.

Thank you,

Have a read through this

 

That helps. Now if I can get it down to a level which I can understand,I'll be in good shape. It seems to be straight forward though.

Thank you very much,
