You would expect this. When activated, Vista is licensed to run only on one 
computer.  If you install it to another computer (or the same computer with 
different hardware) you would have to reactivate it with Microsoft, as it 
is not now recognising the same hardware.

In this case, I imagine Microsoft would regard it as a second use, for 
which you would have to purchase an additional licence.

But I have no experience with activation---so I guess you should try them 
and see if you can persuade them that it is the same computer. I believe 
they are reasonably lenient about allowing hardware upgrades. I doubt this 
situation would qualify, unless perhaps you can persuade them that your 
original computer is no longer alive.
