Please keep in mind that for legal purposes, this website cannot provide (or allow to be provided) links that provide unlicensed access to copyrighted material. The NBA is very aggressive in copyright protection and as a rule full games which have been uploaded to the web will be removed promptly for copyright violation. I have deleted a list posted above of YouTube URLs to avoid possible legal complications for KingsFans.com. (The few videos I checked had already been removed from YouTube anyway.)
I am not aware of any location where licensed access to old archived NBA games can be found, but if anybody knows, please pipe up!
