Hi skinnydog1973

Insert the OS X DVD that came with your computer and once again restart holding the Option/alt key.

Then startup into your OS X DVD and go up on the menu bar and select Disk Utilities and try to run Repair Disk on your Macintosh HD as described in the following link.

If Disk Utility fails to see or repair your Macintosh HD, then run the Apple Hardware Test from your OS X DVD as per the next link.

Hey man!

I just had the same problem, but I went to preferences/startup disk and changed the startup disk to the Macintosh HD. The world flashing logo means that the mac is trying to boot up from a network and not from the Hard Drive.

cheers!
