Today I was using my MacBook, running 10.5.5. All of a sudden, I got the spinning color wheel, and nothing would work. I couldn't click the menubar, change apps, etc. So, I held down the power button and restarted it. Well, it took about 5-7 minutes to come back on. Once it got to the login screen, I put in my password and it just sat there, doing nothing, with the Leopard aurora background. Finally, once my desktop loaded, I opened Safari. It was very slow, hanging everyfew seconds. Then after about 10-15 minutes of use, everything froze again. I force restarted, and the same thing. I popped in my Leopard disk, and repaired the disk. No problems. I reboot, and the same thing happens. I have late-2006 MacBook, bought on Black Friday of 2006. What's the problem?
