They will cause you serious errors and could force a reformat.
We appreciate your input, and to an extent you are correct; some users have downloaded dozens of codecs to their computer thinking that the more the better in order to play EVERYthing. Unfortunately, more sooner than later, they begin conflicting with each other and cause problems. It is highly doubtful that they would corrupt the operating system enough to warrant a reformat but they could be a serious pain.

Download a standalone player that has all the codecs included into the player.
There is no such thing. Any player available today will not use
every codec available, that would be dozens. Or, if you mean a player that is as close to universal as possible and has the most commonly used codecs, then Zoom Player is the one you want (as I recommended) and Media Player Classic is also very respected as Surfer suggested. I have found little difference between the two, and in the years I have been using Zoom it has only once played a video that MP Classic would not play. I just like the slick interface of Zoom, and it will play full screen with black background. As a side thought, either of these are far superior to WMP in my opinion.

identify what codec you are missing: AVICodec
AVI Codec does not install codecs, it just identifies what codecs are needed for any given video you are trying to run. If the video needs a certain codec and you don't have it, it goes logically that there will be no conflicts with other codecs. AVICodec is not infallible and occasionally will not recognize the video, but many times it is a big help.
