Hi ValouToulouse,
Welcome to Microsoft Community.
Based on the information available (the problem lasted several weeks and there was no Windows update), the problem may be related to the graphics hardware itself.
It could be a compatibility conflict between the driver and other components, or it could be a physical failure.
In some cases, installing the latest drivers for the graphics hardware is not always the recommended option.
Would you mind sharing further tests and observations with us?
