When you upgrade your computer to Microsoft Windows XP, the Start menu and the Windows taskbar may be missing. Also, when you press CTRL+ESC, the Start menu does not appear. However, if you start Windows XP in Safe mode, the Start menu appears correctly.
This problem may occur if you have a built-in video adapter on your computer's motherboard, and then you install second video adapter on your computer.
To correct this problem, turn off the built-in video adapter.
For more information about how to turn off the built-in video adapter, see the documentation that came with your computer.
