Hi,
Firstly, I suggest that you could check for update. Check if there are some security updates need to be installed.
Then open cmd window,run as admin. Type the command below:
dism /online /cleanup-image /restorehealth
Then download and re-install the video and sound card drivers from the manufacturer's official website
Also you could try to create a new user account to log on. Check if the weired squares will be disappeared.
Best Regards,
Carl

Hello,

For better assistance, please include a screenshot illustrating this issue.

Also, run SFC /SCANNOW command in administrative Command Prompt and see if that helps.


If issue still persists, perform clean boot:
