Mac stops responding from time to time I started using Mac yesterday, since then it stopped responding a lot. Each time it happened I restarted the system but it happens again. I also got "he's dead, Jim" error many times on Chrome.

Is there anyway to get rid of this issue?



Installed memory(RAM) : 4.00 GB (3.87 GB usable)
According to this page, "He's dead, Jim" message appears 


  if the operating system has terminated the tab’s process due to a lack of memory


So it seems to be a RAM problem.

If your Mac is still under warranty, take it to an Apple Store to get it look at.
