It is most likely that your graphic/video card is not of high-enough quality. However, this should not effect gameplay in any way other than seeing gray spartans. i just recently purchased a new HP pc that works great with Halo and other games; but, with my previous PC, which I purchased 2 or 3 years ago, had the same problem that your computer is having.
All I can suggest is that you buy a new quality video card if this bothers you severly; otherwise, just stick with what you've got.
