The obvious answer would be the Power Supply Unit (PSU). This starts the computer and without it nothing can work. On the other hand if you have a faulty mother board or RAM, the computer would switch on but nothing would be shown on the screen. The PSU is found on the highest part of the tower. Also check the the switch (if it has) is switched on, and that the power supply cable (the 3 pin one) works.

What is the difference between BIOS and device driver?
In IBM PC compatible computers, the basic input/output system (BIOS), also known as the System BIOS or ROM BIOS , is a de facto standard defining a firmware interface. When in computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.
What test does startup BIOS perform when you first turn on a computer to verify it can communicate with essential hardware devices?
The BIOS (Basic Input-Output System) loads a ROM (Read-Only Memory; a chip that stores permanent bootup instructions) that performs a POST (Power-On Self-Test) when the computer is first powered on, or when the CPU (Central Processing Unit) is soft reset via a triple fault or an untrapped reset command through the keyboard port (by sending the value 254 to the hardware port 100). The POST checks to make sure that there is system memory, and usually at least one drive device (disk or hard drive), and all the other various parts that make up the core functionality of the computer.
What is the term given to the hardware component of the motherboard that stores the first code that is run by the computer when it is turned on?

When determining the appropriate hardware components of a new information system what role must the user of the system play?
When determining the appropriate hardware components of a new information system, you must first, make a system that works effectively. The role of the user must understand what requirements they need to build a successful system.
Is bios or rom are same?
BIOS is software. It tells system software how to communicate with installed hardware. ROM is hardware. It stores a copy of the BIOS, and automatically loads its contents into RAM (the BIOS) when power is first applied to the system. Thus, while the two are related, they are not the same.
