Hey when i try to open Halo and play it it says "We are sorry, but your computers video hardware is below the recommended minumum spec for this game. If you wish to upgrade your computer, please contact your computer manufacturer for any necessary assistance". I press continue anyway from that then the game gets to a certaint point of loading and then says "Your computers video driver is known to have serious issues with the game. A newer version that is compatible may be available. If you wish to update your drivers, Please contact your computer manufacturer for any necessary assistance". I'm desperate for help plz.
