Within the last week, my Macbook has been acting strangely. Here's a list of what has been happening, intermittently:


  • Turning itself off a couple of times (as if I've pressed and held the power button)
  • When turning on, looping the startup bong until I force a shutdown.
  • Frozen a few of times for more than 15 minutes (until I force shutdown).
  • Running warmer more than normal (the vent is warm to the touch).


When it's not suffering from this, the computer seems to run at normal speeds, and I haven't noticed any other issues.


I ran a RAM diagnostic program to check 3rd party RAM and all seemed to be fine.


Would be great to pinpoint the problem. I'm a bit of a noob though! Any help is greatly appreciated! Thanks!
