Mario 64/Monitor prob?

[IceFlow2]

When I play Mario 64 the screen has like a ripple about half way and slowly goes up the screen sometimes. Other times there is like a break in the screen at half way, the top half is further to the right than the bottom sorta. Hope Ive explained my problem good enough.

All my other roms/games work fine.

mabie due to the refresh rate or a bad rom, also make sure your ATI drivers are up to date, i hear those can be a real pain in the ass
