Help needed - MBP keeps restarting.

Question

So today I turned my Macbook on and I was browsing the Internet and suddenly the screen turned grey and it began to load for a few seconds and then showed my home screen as if Id just opened my computer - all windows that I had opened a second ago were gone. Now it happened once but in the last 10 minutes its happened frequently. I have noticed whenever I click the 'documents folder' my documents appear smaller and highlighted and my mac wont let me choose them - I havent added anything new in weeks. A few seconds after I click documents it goes to the loading screen and my home screen appears as if I had just opened my macbook. Help please? The mac doesnt turn off, the screen just resets itself as if its just been turned on

This could be any number of problems but my first step would be Restarting your computer and resetting the Pram. To do this restart your machine and hold Command + Option + P + R until you hear the start up chime for a second time.
If that doesn't fix your machine then you can try an Archive and Install by using your OS install discs that came with your computer. What this does is replaces your Operating System with a clean fresh copy from the discs and then puts all of your files and user settings back in the correct place. You won't lose any of your files or applications but it is still a good idea to back them up.
If the problem still persist then it is most likely hardware related and you would need to take it to an Apple Store or a Certified dealer for repair.
Hope this helps,
