Hard drive not detected

Hi,

four days ago my macbook pro stopped working while I was doing internet. I had to shut it down but it never booted up again. I tried multiple times to format it with disk utility but it never worked utile at my .... 25th attempt, disk utility finaly detected it so i formated it but when I tried to install osx, the disk couldn't be detected just as before.

I though that my HD was dead so i bought a new western digital scorpio blue 320 GB 5400 rpm. Now, it's the same story as before, my new hard drive is never recognize by the installation cd...

I dont know what to do now. I'm exhausted to try the same things again and again.

If anyone has a solution PLEASE !!! HELP ME.

more infos:

- The drive is turning (it has power)

- With my first HD, i couldn't open the OSX partition but i could open the Windows partition.

- With my new HD in, the installation cd of OSX AND windows cant detect the hard drive.

If you boot from the install disc, select language, and on the next screen go to the menu bar, select utilities>disk utility, does it show up?

i've done it so many times... its only the disc of the optical drive that appear
