New mac user; not sure what I did or what to do.

I would start with the usual troubleshooting items.
Reset the NVRAM by restarting the Mac and immediately pressing the Command, Option, P and R keys at the same time and holding them until you here the Mac startup chime for a second time.
Second restart from the Install DVD. Use Disk Utility in the Utilities menu to Repair Disk on your HD. After restarting into your user account go to Apps/Disk Utility and Repair Disk Permissions on your starup volume.
