So I'm new to this forum as a poster but I have been visiting the site daily for about 2 years. I have an early 2011 MacBook Pro 13" 2.7 GHz i7 4g RAM and as of an hour ago my computer has suddenly decided to act as though it had a virus. I know it's not a virus but let me explain. I was attempting to watch a soccer game online and Safari starting getting slow and giving me the beach ball. Suddenly, everything froze and I had to force shut down my computer. When I tried to turn it back on the white screen with the apple logo and the loading dial seemed to be on the screen for around 7 minutes before the screen turned simply white. A minute later, the screen loaded completely. But for every move of the mouse or click of an icon or opening of an application or basically anything at all, the computer will freeze and give me the beach ball for as long as a couple minutes until I can do just a little bit more to get to my destination. I seriously have no idea what could be wrong with it. Also, my laptop is pretty essential to me since I'm at college write now.
