Hardware upgrade

I just 'upgraded' from amd integrated graphics in a laptop to another laptop (I just swapped the hard drive) with Intel integrated graphics core i7 2670qm. I use gnome 2 as my interface of choice and now i am not getting any of the cool effects and searching features. I see no drivers in the additional drivers just a blank screen. I don't know what to do. i've installed a bunch of stuff to get it working, nothing has worked.
one site i tried is: http://ubuntuforums.org/showthread.php?t=1943652

Is there a way to tell ubuntu to recheck all drivers like it does during installation?

we are also discussing the matter over here: http://ubuntuforums.org/showthread.php?t=2133095&p=12592273&posted=1#post12592273
