NVIDIA drivers problem

Hi everyone, I am new to this distribution, just trying it for the first time.
Trying to install it on an old computer: AMD Phenom II 555 with NVIDIA GT710 videocard and 4Gb RAM.
Downloaded "Q4OS Aquarius, Trinity, install-cd - 64bit / x64".
Installed and booted successfully - no problems.
The system suggested my computer is powerful enough to run KDE so I installed KDE.
Installed and booted successfully - no problems.
Videocard was detected and I was asked if I want to install the NVIDIA drivers for it.
Installed successfully and rebooted.
Now the system loads to the KDE login screen, and after entering the password it loops back to the login screen.
Any help?

Re: NVIDIA drivers problem

Maybe the problem is with uppercase/lowercase characters & digits in your password. Check the Caps lock and Num lock leds.

Welcome
First follow @hchiper advice above please. If the problem turns out to be Nvidia drivers related, switch to the console and run a single command:
$ nvidia-uninstall
follow on screen instructions and reboot.

The password is correct. The system starts loading and after a few seconds on a completely black screen it goes back to the login screen.
Will try nvidia-uninstall.

Re: NVIDIA drivers problem

it could be a permission issue with the cd image.

I know the plasma live version works because I use that with my GT710 nvidia card, but I'll  download all of them and look.

Btw, I did send you email on joining your dev team/mail list @q4osteam.
