my imac (just 14 months old) suddenly will not reboot, all

This answer was rated:

my imac (just 14 months old) suddenly will not reboot, all I get is the running clock under the apple, I had to force quit because my screen froze, which hardly ever happens. Is there a way to "safe start"
You might have to reinstall the operating system but first let's try a few things.

Reset the PRAM. Reboot and immediately press and hold these four keys; OPTION APPLE P R
Keep those key down until you hear the Mac Chime at least three times then let the keys up.
If it comes up then run the Disk Utility Program in your Utilities folder and verify your hard drive.

Let me know how that turns out.

Before I reset the PRAM, won't that destroy my desktop? My wife had lots of stuff there, I recall that this may wipe out some files, Can you advise before I try this?
No Resetting PRAM will not effect your files.

My keys don't have an apple, but I assume it is Option, Command key, and PR keys . I did that, hear three chimes, but the clock under the apple is turning with no desk top. I assume that you want me to install my original disks ? won't that wipe my hard drive?
The next step is to boot from your system CD. But if you do it right noting will happen to your files. Insert the CD and restart your computer. Immediately press and hold the C key on your keyboard until you see the Apple logo on the screen. Once the computer comes up answer the language question and run the Disk Utility program from the Utilities Menu. Choose the button Repair Hard Drive and Repair File Permissions.

After that try to reboot.

One last question, since we moved our stuff is really scattered, I just tried and failed to find my disks for the iMac, but I did find my 2008 install disks for my laptop with 10.5.2 what would happen if I installed that OS in my imac?
