A new computer would help, but...
Make sure there are no other processes/programs running when you play Halo. Ctrl-Alt-Del to bring up the Task Manager, and end all processes you don't need under "User Name - Owner". All my computer needs are "explorer" and "taskmgr". Shut off your screen saver (don't really know why this helps, but it does sometimes).
If Halo is not working at all, but did before, try uninstalling and then re-installing.
Hopefully this helps.
