I recently switched to 14.04, my laptop config are: 4Gb Ram, Intel core i5 proc 2.4 Ghz I keep Ubuntu updated, but I have a persistent problem of it hanging/freezing randomly. The system becomes unresponsive with mouse and keyboard shortcuts not working and the screen freezes which forces me to use power button to restart manually. Although I have noticed one particular thing, Last time when that happened I was watching a video, but the audio kept playing after the freeze, is this possibly a graphics problem? Any pointers will be helpful.
Thanks
