What should I do when Ubuntu freezes?
I've got Ubuntu 12.04 LTS. and I'm new to Ubuntu. I have problems with crashes that occur semi-randomly.
Sometimes when I start Ubuntu, both browsers (Firefox and Chrome) fail to load. Chrome gives “Aw Snap!” on every site and Firefox exits giving an error. Then I restart Ubuntu and everything is normal. Why does it fail to start when I start ubuntu for the first time?
Sometimes I get “System Program Problem Detected”. I even performed
sudo rm /var/crash/*. It disappers on restart but it then comes back again.
Should I check if my all packages are properly installed? How?
