I've been noticing the performance on my MBP is getting worse and worse. I have the Early 2008 Edition MBP 2.4 GHZ with 4 GB Ram. What I've been noticing is when I'm browsing or typing, it will freeze up temporarily and the spinning beachball thing for 2-3 seconds before it starts back up. It's starting to become more frequent. Also, Youtube videos dont play smoothly at all anymore. Has anyone had issues like this? Is there something I can do to see what the issue is? At first I thought it was a hard drive issue but I've moved a lot of stuff to my ext hd so now there's 100 GB and still the problem persists. I also notice that my laptop runs hotter and battery life is getting worse.
