Your computer screen is black means the major problem is power supply, so that check the power supply.

If Power is good and everything is good means change the OS operating system.

A black screen on a computer can be caused by several issues, including: Software issues: Try restarting the computer or booting into Safe Mode. If the issue persists, try restoring the computer to a previous working state using system restore or reinstalling the operating system. Hardware issues: Check if the computer's internal components, such as the graphics card or the hard drive, are functioning properly. Try connecting an external monitor to the computer and see if the display appears on the external monitor. Power issues: Make sure the computer is fully charged and try a hard reset by holding down the power button for at least 10 seconds. Display issues: If the display appears on an external monitor, the issue could be with the computer's display. Try connecting a different display to the computer to see if the issue persists. Corrupted drivers: If the computer is running on outdated or corrupted drivers, it can cause a black screen. Try updating the drivers from the computer manufacturer's website or using the Device Manager. Try these solutions one by one to resolve the issue. If the problem persists, you may need to seek technical support from the computer manufacturer or a professional repair service.

If your screen has turned black, here are some general steps you can try to fix the issue:

1. **Check the Power**: Ensure that your device (computer, smartphone, TV, etc.) is powered on and the screen isn't simply in standby or sleep mode.

2. **Reboot**: Try restarting your device. Sometimes, a simple reboot can resolve software glitches.

3. **Check Cables**: If you're dealing with an external monitor or TV, make sure all cables are securely connected. Loose or damaged cables can cause display problems.

4. **Adjust Brightness**: It's possible that the brightness setting is too low, making the screen appear black. Check your device's settings to increase brightness.

5. **Safe Mode**: On some devices, booting into safe mode can help identify and fix software issues that may be causing the black screen.

6. **Hardware Issues**: If the above steps don't work, it could be a hardware problem. In this case, you may need to contact the manufacturer or a technician for repair or replacement.

7. **Battery**: If you're using a portable device like a laptop or smartphone, it's possible that the battery is completely drained. Connect it to a charger and wait for a while to see if it turns back on.

8. **Graphics Driver**: Outdated or corrupted graphics drivers can also cause black screen issues. Try updating or reinstalling your graphics driver.

The specific solution may vary depending on the type of device and the underlying issue. If these basic steps don't resolve the problem, you might need to provide more details about your device for more targeted advice.
