    tried booting to safe-mode? hold shift after startup until the grey screen comes up. If you can get logged in go to applications/utilities/Disk Utility, from there repair the permissions and verify your start up disk.

    also you can try reseting your PRAM - hold apple-option-shift-R-P wait for the start up chime to play twice then release.

    Good luck!

      Also try pulling the RAM and putting it back. It may have have become unseated over time if it moves a lot.
