Drive Preparation and Install
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.

Is this a retail copy of Snow Leopard? Are there any error messages when you try booting from the DVD? Are you doing the following;
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Yes it is a retail copy i got from apple store. its not giving me any error messages.
I did exactly what you have in steps above and this is what happens.
after step 4, it goes to a greay screen and after a while DVD stops spining and looks like the computer freezes on that screen.
When I use USB to install, it starts the installer straightway and half way through computer restarts
and comes with a error message saying installer has accoured a error. (which really breaks my heart)
I hope its clear what I am trying to say.
Any luck saving my computer ? What I really trying to do is locate where is the problem is so I dont have to take it to apple store.
