Thanks for the clarifications.
Using the Nvidia driver may be the source of the problem. Unfortunately, the drivers provided by Nvidia can cause problems on laptops. Always use the Nvidia driver provided by the laptop manufacturer, even if it is old.
I suggest you perform a clean install of the Nvidia driver as instructed below and use the latest version provided by Asus for your laptop.
Download the latest driver for your graphics card from Asus's website. Then, use the free DDU tool to remove the current driver. Then, install the latest driver using the installer you downloaded.
I suggest disconnecting from the internet during the entire procedure.
(Turn off Wi-Fi or disconnect the Ethernet cable.)

(Run the downloaded EXE file and follow the on-screen instructions to install the driver.)

See if the system will work stable after this.
