Fix: Windows 7 freezes at a black screen if screensaver is enabled

If your Windows 7 or Windows Server 2008 R2 computer stops responding at a black screen if a screen saver is enabled, applying this hotfix may resolve the issue.

Windows 7 freezes at a black screen

Lets say you have enabled the On resume, display logon screen option for the screen saver.

Now evenĀ  when you use the mouse or keyboard, you are unable to turn on the display – only a restart helps you.

This problem occurs because of a race condition between the CSRSS thread and the WinLogon thread.

In such case apply hotfix from KB976427 to resolve this issue.

Microsoft has released a hotfix to resolve an issue, where a computer that is running Windows Vista or Windows Server 2008 stops responding at a black screen early in the startup process.

See this post if you have Windows 10 Black Screen problems.
