driver problems

hey all, i recently got the "everything big" problem after windows updated, meaning all my windows/screens and icons were massively enlarged, and my resolution seemed to have dropped greatly. in a ttempt to fix this, i went to the properties section for my adapter, and clicked on the "update driver" option.

instead of updating my drivers, this has somehow made windows ignore my graphics card, resulting in an issue worse than the original problem. windows now the thinks i am using a "standard VGA graphics adapter" instead of my usual nvidia 480 gt graphics card (i think thats my card, i'll check). anyway, all help would be appreciated.

cheers,hecham.

thanks for the help, everyone...
