How to solve the computer not turning on

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.
