How to remove and replace COD?

[Ibis]

My installation is old And pretty messed up. I have gone through the "check integrity files" files and reinstalling the Mods
several times but problems remain.
So I want to completely remove it and reinstall from scratch.
Can someone advise me as to the correct procedure.

thanks in advance,
Ibis
