The Power Conversion: AC to DC (Role of the SMPS) As soon as you turn on the switch, the electricity first enters the SMPS (Switched-Mode Power Supply). The Converter: Rectifiers and transformers inside the SMPS draw the 220V AC supply from your home and convert it into +3.3V, +5V, and +12V DC (Direct Current). Power Good Signal: Once the SMPS determines that the voltage is perfectly correct and stable, it sends a "Power Good" signal to the Motherboard. The computer will not start until this signal is received. 2. The Brain Wakes Up: CPU & BIOS As soon as it receives power, the Motherboard’s first task is to wake up the CPU. Instruction Pointer: Upon waking, the CPU immediately looks towards the ROM (Read Only Memory) where the BIOS (Basic Input/Output System) or UEFI is stored. The Map: BIOS is the very first "executable" code that instructs the CPU on what to do next. 3. The Health Check: POST (Power-On Self-Test) The BIOS first conducts a "Physical Exam" known as POST. The Checklist: BIOS checks if the RAM is properly seated, if the Keyboard/Mouse are connected, and if the Graphics Card is functional. The Beep: If everything is fine, the small speaker on the Motherboard emits a Single Short Beep (signifying "All Systems Go"). If any hardware is faulty, the BIOS emits beeps in different patterns (Beep Codes). 4. Setting the Stage: RAM & CMOS Immediately after passing the POST: CMOS: BIOS retrieves "System Settings" (Date, Time, Boot Order) from here. RAM Initialization: The CPU now activates the RAM so that future data can be stored there. 5. Searching for the Soul: Boot Loader Now that the BIOS knows the hardware is functional, it still doesn't know what task to perform. Boot Priority: BIOS checks the location of the OS (Operating System)—is it on the Hard Drive (SSD/HDD) or a Pendrive? MBR/GPT: BIOS reads the first sector (MBR) of the Hard Drive where the Boot Loader resides. This is a small program that "invites" the OS. 6. The Grand Entry: Loading the OS The Boot Loader now begins loading Windows or Linux files from the Hard Drive into the RAM. Kernel Loading: The most critical part of the OS (the Kernel) settles into the RAM and takes control of the hardware. Drivers: The OS now starts all hardware drivers (Sound, Video, WiFi). 7. The Opening: GUI & Desktop Finally, the OS displays the login screen. Shell Execution: When you enter your password, the OS executes the graphical interface (Explorer.exe). The Welcome: The Desktop appears, and all startup apps begin running in the background. 🔑tags (ignore): #bootingprocesskaisekaamkartahai #computermemory #computerstartkaisehotahai #computermemorykyahai #cache #basicinputoutputsystem #rommemorytypes #beepsound #beeptest #poweronselftest Computer kaise start hota hai computer kaise khulta hai computer ki memory cpu ke andar kya process hote hain cpu ke andar kese processes hote hain primary memory secondary memory cache basic input output system rom memory types computer ki memory power on self test power on self test beep codes CPU ke andar kya hota hai beep sound beep test what is beep sound in computer computer ki secondary memory kya hai computer ki mukhiya memory kya hoti hai how computer boots up CPU startup process in Hindi what is computer booting BIOS and POST process Hindi RAM vs ROM explained Computer Basics for beginners CPU operation stages How OS loads in RAM OS Booting process Switched mode power supply(SMPS) OS booting software for pc Computer Hardware explained OS Kernel explained Kernel in OS OS kernel in operating system #ComputerBasics #CPUProcess #rnglory #TechEducation #HowItWorks #ComputerMemory #BootingProcess #HindiTech #LearnComputer #ComputerScience #TechTipsHindi #PCStartup 00:18 Intro 02:32 Computer memory 08:29 Switched-Mode Power Supply 11:27 Basic Input/Output System 13:35 Types of ROM 15:18 Power-On-Self-Test 17:43 Booting
