Glad you got it working. If you do have any problems with the Microsoft downloaded drivers
, then grab the official latest from either of the sites that Fabe or I posted.
RE: DWM being disabled, this confuses me as you said that Aero is running. Let's hope that DWM wasn't disabled on purpose by your graphics card drivers.
Please check if the service is running. Type Services.msc into RUN or SEARCH and press ENTER. Scroll down the list and look for thw Desktop Window Manager. It should be set to startup Automatically and the status should be "Started". If not double click on it and make the correct changes.
