There's probably something actually wrong with your computer or current operating environment.

I'm willing to bet that you have either outdated drivers for something or an app which is interfering with the memory of DirectX and Halo.


The only problem I experience with my computer is that sometimes Halo just doesn't exit (or always crashes on exit). But that's just Halo without any additions to it (other than maybe another d3d9 for Triplehead). I wonder if it has something to do with Windows Vista x64.
