I started having problems with my Mac Book Pro last night. It crashed, and instructed me to restart the computer. I've tried the following with the install CD inside the CD ROM Drive:

1) Restarted it with the OPTION key pressed down
2) Restarted it with the C key pressed down
3) Restarted it with the D key pressed down

The extensive Hard Drive test did not detect any problems. I cannot boot from the main HD or the Install CD. I cannot enter safe mode.

On a regular boot up the computer starts up with gray bars and the gray bars fill the screen, the spinning gear appears and more gray bars on the screen. The screen then turns black and then I get the restart message.

Any suggestions would be appreciated.
