Halo display problem.

[antarus_t]

When halo loads and its at the main screen, right away the screen
keeps on going back and forth from left to right and vice versa. It
wont stop and I cant play. So basically the screen keeps moving and I
cant play. Any help/suggestions? ty, much appreciated, by the way, I
already tried the resolution thingy.

did you make sure that you had the latest patches for halo and the latest
drivers for your video card?!

also make sure that your computer configuration meets req for the game...and
that the game is designed to work with your video card(unless patched games
arent forward compatible, and even then some games dont work with certain
hardware no matter what)

if that doesnt work try shutting down all non-essencial programs
