Desktop computer boot steps

1. Turn on the power supply

• Find the power switch on the back of the computer case, usually a round or square button.
• Press the power switch and the computer will start powering.

2. Press the chassis power-on button

• On the front panel of the chassis, there is usually a button marked "Power" or "Start" button.
• Press this button to trigger the motherboard to start the computer.

3. The motherboard performs a self-test (POST)

• After turning on the computer, the motherboard will perform a self-test (POST) to check the key components of the computer (such as memory, storage devices, and graphics cards) are working properly.
• At this point, you may hear some beeps or see a POST message appear on the screen.

4. Load the operating system

• After POST is completed, the computer will start loading the operating system. The operating system you install (such as Windows, macOS, or Linux) loads from a storage device (such as a hard drive or solid-state drive).
• This process may take several minutes, depending on the size of the operating system and the speed of the storage device.

5. Login user

• After the operating system is loaded, you need to log in to your user account using your username and password.
• If you do not have a user account, you can contact your computer administrator to create one.

6. Desktop display

• After logging in, your computer desktop will be displayed. This is your center for storing files, running programs, and performing tasks.

Tips:

• Make sure your monitor is connected to the graphics card.
• If the computer cannot be turned on, please check whether the power cord is connected and the power switch is turned on.
• If it still cannot be turned on, it may be a hardware failure and you need to contact a professional for repair.
