Step 1: Check Power Supply

• Make sure the power cord is securely plugged into both the power outlet and the computer’s power supply unit.
• Ensure the power outlet is working by plugging in another device.
• Try a different power cord if available.

Step 2: Inspect Power Button and Connections

• Verify that the power button on the computer is not stuck or damaged.
• If using a desktop, check the connection between the power button and the motherboard. Ensure it’s securely connected.

Step 3: Test the Power Supply

• If you have a desktop PC, you can test the power supply unit (PSU) by using a PSU tester or swapping it with a known working PSU.
• For laptops, if the battery is removable, try removing it and then plugging in the power cord to see if the laptop powers on.

Step 4: Check Internal Components

• Open the computer case (if it’s a desktop) and ensure all internal components such as RAM, graphics card, and cables are properly seated.
• Reseat the RAM sticks and any other removable components.

Step 5: Clear CMOS (BIOS)

• If the computer has power but fails to boot, clearing the CMOS settings might help. Refer to your motherboard’s manual for instructions on how to do this.

Step 6: Check for Signs of Damage

• Inspect the motherboard and other components for any signs of physical damage such as burn marks, bulging capacitors, or loose connections.

Step 7: Test with Minimal Hardware

• Disconnect all non-essential hardware components (such as additional drives, expansion cards) and peripherals.
• Try booting the computer with only the essential components (CPU, RAM, motherboard, power supply) connected.
