The five hardware components that are typically checked during the Power-On Self-Test (POST) process are:
1. Central Processing Unit (CPU): The POST verifies the functionality of the CPU, including its speed, cache, and registers.
2. Random Access Memory (RAM): The POST checks the RAM modules to ensure they are properly installed and functioning correctly.
3. Basic Input/Output System (BIOS): The POST verifies the integrity of the BIOS firmware, including its settings and compatibility with the hardware.
4. Hard Disk Drive (HDD) and other storage devices: The POST checks the presence and functionality of the hard drive and other storage devices connected to the system.
5. Graphics Processing Unit (GPU): The POST tests the GPU to ensure it is properly connected and functioning, as it is responsible for rendering graphics on the display.
