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 are some options available for computer hardware recycling?
An option that you have for computer hardware recycling is to first purge your hardware of any personal information. You can then donate the hardware to a charity for those that are less fortunate.
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?
bios
What is the first thing that BIOS checks?
Startup BIOS first checks all the essential hardware components to make sure they're working and displays its progress on-screen.
Which came first the Operating system or the hardware?
This is basically the same question as which came first, the Chicken or the Egg. Its argumentative.
What computer hardware was first to be invented?
abacus
What is fault coordination?
Fault coordination is the process of ensuring that protective devices in an electrical system are coordinated such that the device nearest to the fault disconnects first, effectively isolating the faulted section and ensuring minimal disruption to the rest of the system. This process helps to improve the reliability and selectivity of the protection system.
What are the categories of operating system based on the hardware machine they run?
there are two types of os based on your hardware machine. first is nos and second is cos base.
When you're taking your first drivers test and you get into an accident and you kill someone is that your fault?
Well, I would assume so. You were driving the car, and you were in control. If I am right, you can't blame your driving school for the accident. So in my personal opinion, yes, it is your fault! :[
Suppose you have bought all hardware components required for assembling a Computer After assembling the Computer System which will be the very first software to be installed?
Operating system

How do you fix Nissan frontier alarm system?
You have to first diagnose the fault to figure out WHAT needs to be repaired before you can repair it.
What was first software or hardware?
Have to be hardware. How could you write software if there were no hardware to write it on?
When was operating system introduced?
I assume you mean "When was the first operating system introduced?" Seems to be in the 1950s. See the link below for a very detailed page.
How come when you plug in your walkman nothing appears?
If your plugins are not shown in your system means it is not supported by your system 1)first find if the plugin software is installed in your system 2) If installed means fault in your walkman only first check it out.
What part of the operating system loads first and remains in the main memory?
The bootloader is the part of the operating system that loads first during the system startup. It initializes the hardware and loads the kernel into the main memory, which remains there to manage system resources and execute processes. The kernel serves as the core component of the operating system, facilitating communication between hardware and software. Once loaded, the bootloader typically relinquishes control to the kernel, which takes over the system's operations.
