If your computer is stuck on a black screen, it could be due to various issues, from simple software glitches to hardware problems. Start by checking if the computer is truly unresponsive by pressing the Caps Lock key and seeing if the indicator light changes. If the system seems alive, try a soft reset by pressing 'Ctrl + Alt + Del' to see if you can bring up the security options screen. If this doesn't work, a hard reboot might be necessary. For recurring black screen issues, booting into Safe Mode or using Windows Recovery Environment can help diagnose and fix the underlying problem.
