Macbook keeps restarting, can't get past icon screen

I had to correct my permissions because I couldn't edit my address book and ical. Everything was working fine last night after I did the permission fixes. But when I booted up my Mac tonight, the farthest I could get was the white screen with the Apple icon and the animated circle. After a few minutes, the laptop will reboot itself and continued to do that for 30 minutes. I can't get past that screen. What is going on? How do I fix this? I finally turned off the Mac and am using my Dell.

The question mark on the file tells you that your MacBook wants to start up but can't find a viable OS to start from. Can you start up from the DVD that came with your Mac? If so, go to Disk Utility and see if you can repair the internal hard drive. If you can't see the hard drive from within DU, your drive may have failed, and you may need to replace it. Good luck.
