I was on internet explorer, I had two tabs; Facebook.com & NHL. Com, my mouse pointer disappeared, I held the power button to restart my laptop, I got to log back in, about 11:45 p.m. last night, my mouse pointer disappeared again, I held down the power button to restart my laptop and my log in screen wouldn't come up. I would choose launch startup repair (recommended) my log in screen comes up, but it's only the blue log in screen and my mouse pointer. What does this mean? If I get it fixed, will I lose all of my saved pictures, music, videos and saved word and excel documents?
