Harddisk crashed & black screen

[retowernli]

The harddisk of my Macbook (black, October 2006) crashed, after restarting the folder with question mark showed up.
removing harddisk (unsuccessfullytrying to save some data) and putting it back in - the screen remains dark as I start the computer. the same after inserting a new harddisk - screen doesn't turn on..

many thanks for your help

Use the System Installer CD-ROM to start up your Mac and see if you can find any reference to your hard drive.

If the disk appears, run Apple's Disk First Aid program to check it.
If no problems are found, backup your critical files and reinstall the system software.
If the hard disk does not appear on the desktop, you can also try resetting the Macintosh's Parameter RAM (PRAM) to its factory defaults to help the computer locate the Startup Disk.

Hold down the Command, Option, P and R keys during start up.
The Macintosh should chime at least twice before you release the keys.
Hope this maybe helps????
