Troubleshooting Guide: CPU Won't Turn On

Step 1: Power Supply Check

1. Power Cord: 
   - Ensure the power cord is securely plugged into both the CPU and a working power outlet.
   - Check for any signs of damage to the power cord.

2. Power Button: 
   - Verify that the power button on the CPU case is functioning correctly.
   - Press the button firmly and ensure it's not stuck or obstructed.

Step 2: Internal Connections

1. Power Supply Unit (PSU): 
   - Check if the PSU is switched on (if it has a power switch).
   - Listen for any abnormal noises such as clicking or buzzing that might indicate a faulty PSU.

2.  Internal Connections: 
   - Ensure all internal cables (especially those from the PSU to the motherboard) are securely connected.
   - Check if any cables have come loose due to movement or maintenance.

Step 3: Hardware Inspection

1. Hardware Components: 
   - Inspect the CPU, RAM modules, and graphics card (if applicable) to ensure they are properly seated in their respective slots.
   - Reseat these components if necessary.

2. Cooling System: 
   - Check for any signs of overheating (excessive dust, hot components).
   - Ensure fans connected to the CPU cooler are functioning properly.

Step 4: Troubleshooting Potential Issues

1. Power Surge or Outage: 
   - If there was a recent power surge or outage, unplug the CPU from the power source for a few minutes before attempting to power it on again.

2. CMOS Battery: 
   - Replace the CMOS battery on the motherboard if the computer has trouble keeping time or if it fails to start occasionally.

Step 5: Diagnostic Tools

1. POST (Power-On Self-Test): 
   - Listen for any beep codes or check the diagnostic LEDs on the motherboard.
   - Refer to the motherboard manual for interpreting these codes.

2. External Monitor: 
   - Connect an external monitor to check if the issue lies with the display output.
