Explanation
The flashing LEDs on the keyboard (Num Lock, Scroll Lock, Caps Lock) are often an indicator of hardware issues, particularly power-related problems. Since the system shut down after an extended power outage and is failing to boot properly, this suggests that the power supply unit (PSU) might have been damaged or is malfunctioning. When the PSU cannot provide sufficient power, it can lead to incomplete startup and shutdown behavior like the one described.
