I have a black Macbook from 2007. I have been concerned lately about my macbook. I thought it was the internet acting up but i am unsure at this point if it is. I would open a website with or without videos and the beach ball would just go round and round. I would have to force close safari AND google chrome when i used it. I even tried to open system preferences and it would freeze. Now, I am unsure if it's the internet because I would use my parent's iMac that is a bit younger than my macbook and the videos and sites work fine. They do not crash. I'm concerned because I cant get to what I want and there are important things on my computer that involve work including resume, etc.
