Consider the following scenario:

  • You have a computer that is running Windows Vista Service Pack 1 or Windows Server 2008.
  • The computer has an integrated graphics adapter and a discrete graphics adapter.
  • When you start the computer, you are using the discrete graphics adapter for the display output.
  • You switch the display output from the discrete graphics adapter to the integrated graphics adapter.
  • A power event occurs. For example, when your AC power cord is disconnected, the power supply system fails over to a DC power source.

In this scenario, you may receive the following Stop error:

Stop: 0x00000018 (parameter1, parameter2, parameter3, parameter4)
