When you start a Windows Vista-based computer, the system may stop responding (hang) at a black screen.

Additionally, you may experience the following symptoms when you try to recover from this problem:

• If you restart the computer, press F8 before the Windows Vista progress indicator appears, and then click the Safe Mode option, the same problem occurs.
• If you start Windows Recovery Environment (WinRE) to restore the Windows Vista-based computer, WinRE stops responding.
• If you try to use Windows Vista installation media to repair the system, the system stops responding.
