Can you hit ctrl+alt+F1 to get into a terminal? Does it let you log in there and type commands while it is still stalled? What kind and version of linux are you using? What kind of computer do you have? How new is it? and How much memory do you have? –  Jarvin Sep 8 '10 at 16:45
    
Can you switch into terminal with Ctrl+Alt+F[1-6] when it happens? Did you look for dmesg? /var/log/messages? /var/log/syslog? What graphical card, driver version, X version do yo have installed? –  PocketSam Sep 8 '10 at 16:48

These are some of the solutions other people used in other forums

  • Try using another Web browser , in many other forums people say it crashes due to Firefox activities

  • Try swapping , Instructions ---> https://help.ubuntu.com/community/SwapFaq

  • Try this and tell me if it works

Try disabling "Cool n' Quiet" in your Bios or do the following:

Open a Termina, then

1.

sudo su

cp /etc/init.d/powernowd /etc/init.d/powernowd.bak

gedit /etc/init.d/powernowd

2. Just after the line

#! /bin/sh

insert the following:

exit 0

3. Save the file and restart.
