When you try to upgrade the video driver on a Windows Vista-based computer, the screen may go blank. In this situation, nothing happens when you move the mouse or when you press CTRL+ALT+DELETE. If you turn off the power and then restart the computer, the desktop is displayed correctly. However, you receive an error message that states that the newly installed driver is incompatible with Windows Vista.


This problem occurs under the following circumstances:

  • The driver queries Windows Vista for the available system memory.
  • Windows Vista issues an incorrect value in response to this query.
