Hm...sounds to me like you don't have enough RAM in your box. System specs? You'll need at least 512 to run Halo.
I would reinstall it, see if that helps, if not, then run the fix that Chewy provided up there in Simon's liink.
And...er...yes, you do need the CD Key if you intend on reinstalling...why? I mean, you don't have an illegit copy...right?
