Follow these steps to identify and resolve boot issues, or contact 220 Internet Services support via Open a Ticket for further assistance.

Quick Fix Steps

Before moving to more advanced troubleshooting, try these simple checks to rule out basic hardware and peripheral issues.

1. Ensure the power cable is firmly connected to both the computer and the wall outlet.
2. Disconnect all external devices such as USB drives, printers, webcams, and external monitors, then attempt to restart.
3. Check that your monitor is powered on and the video cable is securely plugged into the correct port.
4. Listen for unusual beeping sounds during startup, as these often indicate specific hardware errors.

Detailed Instructions

Perform a Hard Reset

A hard reset clears residual power from the motherboard and can resolve temporary startup glitches.

1. Shut down the computer completely.
2. Unplug the power cable from the wall and the computer.
3. If you are using a laptop, remove the battery if it is removable.
4. Press and hold the power button for 30 seconds.
5. Reconnect the power cable and battery, then turn the computer on.

Boot into Safe Mode

Safe Mode starts Windows with a minimal set of drivers, allowing you to determine if a third-party driver or application is preventing startup.

1. Force the computer to turn off by holding the power button for 10 seconds.
2. Turn the computer back on.
3. As soon as you see the manufacturer logo, hold the power button again to force a shutdown.
4. Repeat this process two or three times until Windows enters the Windows Recovery Environment.
5. Select Troubleshoot > Advanced options > Startup Settings > Restart.
6. Press 4 or F4 to enable Safe Mode.

Run System File Checker

Corrupted system files can prevent Windows from loading correctly. You can repair these using the Command Prompt.

1. Boot into Safe Mode or use a Windows installation USB to access the Command Prompt.
2. Type the following command and press Enter:
3. sfc /scannow
4. Wait for the scan to complete and follow any on-screen prompts to repair found files.
5. Restart your computer normally.

Troubleshooting

Check for Pending Updates

Incomplete Windows updates can cause boot loops or black screens.

1. Boot into Safe Mode.
2. Go to Settings > Update & Security > Windows Update.
3. Select Check for updates and install any available updates.
4. Restart your computer.

Uninstall Recent Updates or Drivers

If the issue started after a recent update, rolling it back may resolve the problem.

1. Navigate to Troubleshoot > Advanced options > Uninstall Updates.
2. Choose to uninstall the latest quality update or feature update.
3. Restart the computer and test if it boots normally.

Test Storage Health

A failing hard drive or SSD is a common cause of startup failures. If you hear clicking noises or the drive is not detected in the BIOS, the hardware may need replacement.

• Enter the BIOS/UEFI during startup (usually by pressing Del, F2, or F12).
• Verify that your primary storage drive is listed and detected.
• If the drive is missing, check the physical SATA or NVMe connections.

Note: If you have recently installed new RAM or a new hard drive, ensure they are seated correctly in their slots before attempting to boot.

Warning: Avoid forcing a shutdown by holding the power button unless the system is completely unresponsive, as this can lead to data corruption.

If these steps do not resolve the issue, your computer may have a deeper hardware failure.
