Ubuntu has suddenly stopped working and everything has become unresponsive, including the mouse, keyboard. I waited for almost an hour to make it settle itself. Finally, I had to shut it down and restart it and then it was ok.
details:
When this happened, I opened almost 9 tabs (i don't know whether this can cause a crash in ubuntu). I have Ubuntu installed in windows 8 using Wubi. I never had this problem before. I use 12.04 LTS.
What might be the possible reason for this? Is this due to some mis-management of system? Or something else?

brand : Samsung
model : samsung np 300 e5c a02in

graphic card : intel 4000 hd graphic card
I don't remember installing any custom drivers manually memory given to ubuntu partition : 30 GB (I am using far below this) processor : 3rd gen i5.
