- Click the OK button on the screen.
- Click the Restart button on the screen.
- Power-cycle the system.
- Press CTRL+ALT+DELETE to restart the system.
The correct answer is 3.
The only solution possible when a system halts on the blue screen is to power-cycle the machine. There is no active user interface for interacting with the system. The system can be configured to automatically restart on a system failure, in which case the reboot occurs without a power-cycle. However, in this case, the technician does not have much of an opportunity to observe the diagnostic information on the blue screen.
