So every other day or so my macbook freezes and a clicking noise is heard coming from within the macbook. The only solution ive found is to hold the power button and to start it up again. I noticed that the noise comes from around the top left portion of the laptop, but that may be simply because the noise escapes through the vent. Also it recently started to shut off by itself and the force restart screen in different languages pops up. Any one have any idea why this may be? 2GB RAM, and i have about 20 GB of storage available. Thanks
