Jun 18, 2012 9:28 AM in response to Dv2191by BDAqua,You have Firmware password protection setup in Mac OS X ...
http://support.apple.com/kb/HT1352
It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.
Force Removing Password Protection
1) Add or remove DIMMs to change the total amount of RAM in the computer.
2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

Jun 22, 2012 10:26 AM in response to Dv2191by BDAqua,Can you now boot from your Install Disc?
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Jun 22, 2012 11:07 AM in response to Dv2191by Neville Hillyer,When you have cured your initial problems I would do the following:
I assume it is an Intel Mac and hence able to use Snow Leopard.
For best results:
- Backup anything you may want later onto a DVD or external disk
- Boot from the Snow Leopard install DVD
- Reformat (erase) the whole drive
- Optionally split the drive into 2 partitions - you could put separate OSs on each
- Install Snow Leopard and resist the temptation to use earlier software or preferences as they may be corrupted
Good luck

Jun 22, 2012 11:28 AM in response to Dv2191by Neville Hillyer,You can buy Snow Leopard here:

For details about upgrading this to Lion or Mountain Lion see:

In each case check that your Mac complies with the requirements.
If you are not in the US you should use the Change Country link at the bottom of the page.
