Video card driver doesn't support Aero effects

hi everyone, i got some problem with my windows 7 ultimate 7600 . .

when I choose themes aero, why it's just changing the wallpaper, toolbars and other effects do not change??

it say ; problem found "Video card driver doesn't support Aero effects"

The current video card driver isn't compatible with the Windows Display Driver Model (WDDM)??

when i used windows vista it works well but in 7600 version it doesnt work.

my graphic card is sis mirage3+ (sis m672)

how to solve this problem??

thx a lot. .

to enable aero to work properly ,the graphic card needs at least direct x 9 or higher, you're card unfotunately does not support that mode ,is the graphics onboard or in a slot? maybe advisable to invest in a newer card
