Here’s a step-by-step guide to help you troubleshoot and fix Windows installation errors related to power supply issues:
Precautions:
- Make sure the computer is properly grounded, as static electricity can damage internal components.
- Avoid touching sensitive components with your bare hands or using a wet cloth.
Step 1: Check Power Supply Settings
- Press the Windows key + X and select “Power Options”.
- Click on “Save changes” to save any recent power settings.
- Look for the “Additional power connections” section and ensure that the “Device connection type” is set to “AC Power”, not “Battery”.
Step 2: Check Power Supply Unit (PSU)
- Open your computer’s case and locate the PSU (power supply unit).
- Verify that it has enough power to support all components, including the CPU, RAM, hard drive, and graphics card.
- If you’re using a desktop, check the wattage of the PSU. Most desktops require 650-850 watts.
Step 3: Test Power Supply
- Connect the power supply unit (PSU) to your computer using an HDMI cable or another power outlet.
- Press the Windows key + X and select “Power Options” again.
- Click on “Additional power connections”.
- Select the PSU as the primary source of power.
Step 4: Check Graphics Card Power
- If you have a dedicated graphics card, ensure it has enough power to support your system requirements.
- Verify that your graphics card is properly connected and configured in your BIOS settings.
Step 5: Update BIOS
- Go to your computer’s manufacturer website or search online for the latest BIOS update.
- Follow the installation instructions for updating the BIOS.
Step 6: Run a System File Checker (SFC) Scan
- Press the Windows key + X and select “Command Prompt (Admin)”.
- Type
sfc /scannow
and press Enter.
- The scan will check and replace corrupted system files, including those related to power supply issues.
Step 7: Run a Driver Update and Firmware Check
- Go to your computer’s manufacturer website or search online for driver updates and firmware checks.
- Ensure that all drivers are up-to-date and compatible with your system requirements.
Step 8: Perform a System Restore
- If you’re having trouble booting into Windows, try performing a system restore from the last successful backup.
- Go to “Control Panel” > “System and Security” > “Backup and Restore (Windows 10/8/7)”.
- Click on “System Protection” and select “Set all system restores to this point”.
- Choose the most recent restore point before the power supply issue occurred.
Additional Steps:
- If you’re still experiencing issues, try running a third-party diagnostic tool, such as CPU-Z or GPU-Z, to identify any potential power supply-related issues.
- Consider upgrading your power supply unit (PSU) if it’s old or undersized for your system requirements.
By following these steps, you should be able to troubleshoot and fix Windows installation errors related to power supply issues.
