Am new to this forums as well as for Windows 7. using this system from last 2 weeks. I like its all rich feature including the Aero theme. But from last few days, while working with of the files, system gives me an error message stating "The color scheme has been changed to Windows Basic" and Aero theme automatically changes to the basic. Sometimes it use to come frequently and there is also no check box to stop it. Why is it happening ?I need some help to get rid of this problem? Could you guys ? Help appreciated.
