There may be many reasons why the computer has a black screen after upgrading to win11. Here are some possible causes and solutions:
1.Driver compatibility issues:
In Windows 11, the drivers of some hardware devices may not be fully compatible. This can lead to a black screen when the system boots.
Solution: Try updating the drivers of all hardware to the latest version, or check if there is also a driver compatibility issue in the win10 environment.
2.System Setup Issues:
During the upgrade process, the settings may be incompatible, resulting in the system not starting properly.
Solution: Try resetting the system settings to the default state, or check if there is a similar problem in the win10 environment.
3.System Update Issues:
During the upgrade process, the update may be incomplete or incorrect, resulting in the system not starting properly.
Solution: Try to use System Image Recovery in Windows Recovery Tool to restore to the state before the upgrade.
4.Hardware issues:
During the upgrade process, the system may fail to boot due to hardware failure.
Solution: Check the hardware for damage, such as memory sticks, hard drives, etc. Try removing some non-essential peripherals or using the internal hard drive to boot your computer.
5.System File Corruption:
System file corruption may occur during the upgrade process.
Solution: Use the "Command Prompt" in the Windows Recovery Tool to run the SFC ScanNow command to check and repair the system files.
If none of the above methods can solve the problem, you can consider the following steps:
- Safe Mode Boot:Try starting your PC in Safe Mode, and if it works in Safe Mode, it might be due to a problem with recently installed software or drivers.
- System Restore:If you previously created a system restore point, you can try to restore the system to its pre-upgrade state.
- Contact Support:If the problem persists, we recommend contacting the hardware manufacturer or Microsoft Customer Support for assistance.
