You can try these at your own risk*
1) If things are not working correctly, or one function of your computer is not functioning correctly, shut down the computer, turn off all powered devices connected to the computer. Wait 1 minute, and then power everything back up and see if it fixes the problem.
2) If you get a question mark, or an empty folder when you turn on your Mac, try putting a bootable cd in the drive and holding the "C" key down until you see the happy Mac. You can run utilities to repair problems.
