In several years using Linux is the first time I encounter this type of error, although it seems not to be new. After performing a new installation of Debian Buster, every time I tried to log in with my account in normal mode the screen was black and never got to show the desktop.
Since (unfortunately) it is a common problem in some laptops, I proceeded to log in by console (Ctrl + Alt + FN) to start debugging and try to correct it.
To my surprise, every 20 seconds I see an unbearably annoying sign that prevents any task. For example, if I have nano open to modify the sourcelists, the text shown on the screen (deb http ://deb...) is replaced by the error message, forcing me to close and reopen nano to continue editing the document. In the same way, it prevents updating repositories, installing applications or making modifications, get logs, and so fort.
Conclusion: I can't use Debian 10 on my laptop at the moment and I can't find a way to correct the error on my own. I tried different types of installations (DVD, Net, Live), in all the same thing happened. I would appreciate any help you can give me, since I need it to work (at the moment I am with backup laptop, but less powerful) and honestly I would not like to have to change distro.
I leave a capture of the error, although I doubt it is very helpful. I also attach the features of the Laptop:
ASUS ROG GL553VD
+ i7 7700HQ
+ Intel HM175 Express Chipset
+ NVIDIA GeForce GTX 1050
OS: Debian 10
