ahmadddddddd; Hello - My Welcome to the forum.

Indications are that the problem might be graphic's driver related.
Let's take a look and see what we have to work with - what is installed :
Boot to the login screen and at this screen key combo ctl+alt+F1 to gain a console interface.
Log into the system with your credentials ( username and password, no response to the screen when password is entered - enter password blindly and hit the enter key ) .

As this console does not have the amenities of a terminal emulator we use a pastebin site to relay requested information:
In this interface execute terminal commands:

lspci -vnn | grep VGA -A 12 | nc termbin.com 9999
dpkg -l | grep -i nvidia | nc termbin.com 9999
lsmod | grep nvidia | nc termbin.com 9999

the results of these commands is a URL back in terminal, pass these links back here and we access these files to see the result of the terminal commands.
From this information we get an idea of where next to go and what to do.

it's all in the process
