While using my laptop today for a span of 20 minutes I encountered a problem. My laptop suddenly froze. I was listening to music when the screen froze but the music was still playing. I've only recently installed ubuntu (two hours ago).

The issue is not overheating, it was at 50Celcius at the time it froze and my CPU was only at 10% on each core. It wasn't a out-of-memory issue either because I was only using 907mb/5763mb avaliable.

I'm currently using the NVIDIA binar driver - version 331.113 from nvidia-331-updates. My GPU is an NVIDIA GT 620M with 1GB of vram.

I think it might be a driver issue, because I was able to exit the xserver (cntrl + alt+ f3) and check my usage information using htop.

Please help me resolve this issue, oh and my system is version 14.10 :)

EDIT:

Would the following be an approach that would fix anything? 

sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity
sudo shutdown -r now

or would it cause more damage?

As you're familiar with Ctrl+Alt+F1, I suppose you're more technical then the reputation 1 you have here would suggest...

The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware.

If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA. As the xorg.edgers group ask not to give installation instructions directly without linking to their page, this is the best I can do.

If you don't know what a PPA is or don't know how to choose different drivers or need some guidance after reading their page, leave a comment below.
