I installed Ubuntu Natty on my machine and sometimes it freezes even when I perform no operation. I have installed restricted drivers, but no luck. My system config

Intel dual core 3.0GHZ
2gb ram
Nvidia Geforce 9500GT
160GB Hard drive

Log file http://paste.ubuntu.com/686993/

Kernel log http://paste.ubuntu.com/687003/

Kernel log 12-09 http://paste.ubuntu.com/687628/

Any pointers to solve my system from freezing?

Do you also have Windows on that machine? Does it freeze as well? –  user6658 Sep 11 '11 at 16:11
    
Yes.I have windows.But windows xp doesn't freeze! –  blakcaps Sep 11 '11 at 16:16
    
Could you open up the Log File viewer and paste kern.log or kern.log1 to paste.ubuntu.com? –  user6658 Sep 11 '11 at 16:21
    
My guess would be the NVidia card, I've experienced similar issues. WHat drivers are you using? –  RobinJ Sep 11 '11 at 16:37
    
He appears to be using the proprietary Nvidia drivers. The kernel log doesn't seem to have anything surprising in them. Does the system just stop dead and freeze? Does it slowly degrade until death? –  user6658 Sep 11 '11 at 16:39

You're using Nvidia's 173 version driver. That is a very old driver version for older cards. You should install 'nvidia-current' through the program "additional drivers". If the program is finicky and won't show it or let you, then enter this in a terminal:

sudo apt-get install nvidia-current

Reboot, then see if your stability improves.

I was getting these freezes too, but I already had nvidia-current. I'm not sure if this will help. –  Christopher Kyle Horton Sep 11 '11 at 17:47
    
Regardless, if your GPU is supported under the current drivers it is advised to use the nvidia-current package instead of those ancient drivers. –  user6658 Sep 11 '11 at 19:25
    
Thanks.System freezes even after installing current drivers –  blakcaps Sep 12 '11 at 2:36
    
The kernel log you attached earlier today only covered 9/11. Did it freeze up at all today before just now? If not, could you re-upload kern.log? –  user6658 Sep 12 '11 at 4:31
    
Yes.It freezes again.I posted the log file –  blakcaps Sep 12 '11 at 13:56
