The computer did it again!

Man thats great! This is the 3rd time the computer kinda crashes down and i get to lose all my stuff in it! All my photos, music, memories, files and so many other stuff that i just wish i had kept and stored in a safe place ....but by the time i decide to do its always too late....man im upset at this computer, and at myself.....i'd better learn my lesson before it happens again, or better yet i won't put any of my stuff in this computer anymore.....
