3 questions50 points

1.What does firmware do before the operating system loads?

Loads user applications from storage after the desktop session starts.Chooses graphics settings inside each game or creator application.Initializes hardware, applies startup settings, and prepares the system to boot.Controls case airflow without using motherboard sensors or fan curves.

2.Why might a fitting CPU still not boot?

A physical socket match is enough evidence when the cooler mounting lines up.Display cable generation determines whether CPU microcode can load.The storage drive format controls whether firmware can initialize the processor.The board may need firmware support for that exact processor generation or model.

3.What can debug LEDs help with?

Confirming final operating-system driver stability after boot.Identifying which startup stage or part category is blocking POST.Measuring long-term storage capacity before the drive is formatted.Replacing lane-sharing notes in the motherboard manual.
