Steam fails to start

Steam fails to start and does not generate an error message - what is happening?

Steam may fail to start and silently terminate, or it may continue running in the background without loading the Login dialog.

To determine whether Steam has silently terminated or is still running, please check the Windows Task Manager:

  1. Press the CTRL, ALT, and DEL keys simultaneously
  2. Click the Task Manager button and select the Processes tab
  3. If you can locate Steam.exe under the Image Name column, Steam is running in the background
