Answer 1

Did the computer ship originally with a Tiger 10.4.x system, and was the Snow Leopard 10.6
disc used to upgrade the OS from 10.4 to 10.6? Or are you using a Leopard 10.5 disc?
Sometimes an error can result when reinstalling a later OS in a computer that had been
running an older computer, when the former setup had seen a firmware update. And in
a few other situations, if 10.5 was skipped, and OS 10.4 to 10.6 was the path, a few users
had noted problems later on. Since you did not note if the computer was new enough to
have shipped with Snow Leopard (thus perhaps had AppleCare plan coverage, too) these
other questions arise to find those details.
There is some conflicting (or missing information) in your posts; just enough
to see the problem may be in what you have and how you are using it.
Is the latest software version you have a full retail version of the OS X, or was it an upgrade
disc (such as the low-cost upgrade for Snow Leopard) used over an older 10.4 OS X version?
Was a firmware update performed on the computer with the other installation of this software
before you replaced the hard disk drive? Sometimes a firmware update to the logicboard may
cause a problem in later installs of an older OS X than the last one the firmware update was for.
If there were jumper pins to be set specific to use it correctly in this computer, before installing the
new hard disk drive, and if they were not set accordingly, the computer may not see an install disc
or be able to use the disc to install an OS X. Other difficulties may result, if not immediately.
There are details missing in this discussion which may pertain to the outcome.
{And I pointed out your new thread on this same topic to forum moderators, since
you already had this one with replies; as duplicate questions are often not helpful.
That was in the Tiger 10.4 discussions area.}
Good luck & happy computing!
