I updated what I could through system and now Halo works
but when I play Halo the game sorta lags a bit but I think thats normal and thanks for all your help.
Halo while it does work will after a while freeze up and a blue screen will
appear then restart.
Also I'm not sure how to check my drivers and stuff are but I know that I have a laptop with Windows XP Professional Edition with an AMD Athlon XP 2400+.
