I think I know what the problem is. You probably need to install the Halo 1.07 patch, as there is an incompatibility error between 128 MB cards, Halo PC, and Windows XP Service Pack 2.
I have played the game on this pc before.
My brother has it installed on his pc (would there be a clash with the key code being on 2 pcs?)
Talk about ignorance. Yes. In fact, this goes with any PC game today. In the User's License Agreement, it clearly states that you are only allowed to install one legal copy on one PC. That means you aren't allowed to install the same copy of Doom 3 with the same CD-key on three different computers. You can still, let's say, play Halo campaign if you install the same CD with the same keycode on two computers, but you can't play multiplayer on a LAN or over the internet. (even though nowadays you can find a new copy of Halo for just $20, seriously, don't ask people why you can't play with others when you installed the same game on multiple computers with the same copy when you should just buy another copy if you wish to do so.)
The reason they do this is to prevent illegal copies from being created, and that's what CD keys are for. However, if all you wish to do is to simply play the Halo campaign, then just install the patch.
