Win7 suddenly turned into a gray screen with a face in the middle. What happened?

A gray screen suddenly appears after Win7 is turned on, and there is a face occlusion in the middle, which may be caused by the following reasons:

Graphics card driver problems: Sometimes, graphics card driver problems may lead to abnormal screen display. You can try to update or reinstall the graphics card driver to solve the problem.

Hardware problems: It may be related to computer hardware, such as graphics card failure or connection problems. You can check whether the video card is properly installed and connected.

Operating system problems: Damage or errors in operating system files may cause abnormal screen. You can try to use the safe mode of Windows 7 to see if you can start it and try to repair the system files.

Virus or Malware: Malware infection may cause computer abnormality. Use Safe Boot Mode and run antivirus software to scan the system.

Display setting problem: The display setting or resolution setting may be incorrect, resulting in abnormal display. Try to enter safe mode and adjust the display settings.

Hardware compatibility problem: Some hardware may be incompatible with Windows 7, resulting in an exception. Check whether the recently installed hardware or drivers are causing the problem.

If the above methods can't solve the problem, I suggest you consider the following measures:

Try to enter Safe Mode: Press F8 several times when turning on the machine, and then select Enter Safe Mode. If you can enter safe mode, you can try to identify and solve the problem.

Create a system restore point: If you have created a system restore point before, you can try to restore the system to its previous normal state.

If the problem still exists, it is best to consult professional technical support or send it to the computer for repair to further diagnose and solve the problem.
