power cycle

When a Windows PC fails to load, it may be due to hardware malfunctions or corrupted software. A power cycle can be attempted by powering down the PC, disconnecting peripherals, waiting five minutes, and then rebooting. If unsuccessful, users may be directed to the Windows Recovery Environment (WinRE) for troubleshooting options. If WinRE does not appear, the three-boot method can be used: turn off the PC during the boot process three times to access WinRE. In cases of a "Black Screen of Death," the three-boot strategy may help, and users can restart the video driver with Windows + Ctrl + Shift + B. Accessing Safe Mode through Advanced options > Startup Settings > Restart may allow users to roll back updates or uninstall applications. If Safe Mode is inaccessible, Startup Repair in WinRE can fix corrupted settings, and Uninstall Updates can revert recent changes. If WinRE fails, users can check the BIOS/UEFI by pressing a designated key during startup, allowing for diagnostic checks and resetting to default settings. If all else fails, reinstalling the operating system may be necessary, either through the Reset this PC option in WinRE or by creating installation media. In cases of suspected hardware failure, if the PC shows no response when powered on, it may indicate issues with the motherboard or power supply. Listening for beep codes can provide diagnostic clues, and resources for component replacement are available online. Seeking professional assistance may be advisable if the repair seems complex.
