I have tried all solution advices on askubuntu platform. But no way to solve that login loop issue.
When I select the latest Nvidia proprietary tested driver (nvidia-367) , ubuntu stucks on login loop.
Also I tried to erase all disk and reinstall ubuntu but no way to solve that issue.
By the way it occured after an software updater alert and I didn't read it and just accepted(that was different than software updater i think it was about drivers).
So what can be the main problem and why erase all disk and reinstall ubuntu couldn't work ?

i used to have the 7737 version of that laptop but i don't remember using 14.04 on the bare metal with that one, it was 16.04 mostly and maybe 15.10.
If you don't have a specific reason to be stuck on 14.04 then i would recommend upgrading to at least 16.04 as there are many worthwhile improvements in hardware support for that laptop.
Make sure you have the graphics drivers ppa setup , you should use the drivers nvidia-304
To do that just run this
That version is correct at the time of writing, if anyone is reading this later they should check the recommendation on this page https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
