AA problems

i have a problem.........
hey guys
umm... well...
i have a problem with the AA on my sim/video card.
I can have the in sim AA on but jaggies are still massive which ive never had before on my old machine. and then i triued turing my vid card AA up to 4x which is full and the screen when in the menu of the sim was completely haywire... so i turned it down to 2x +Q
and the jaggies reappeared. so i ttried a mixture of 2x+Q and in sim AA and no diferenc....
does anyone know what could be up?
cheers
