Verifique este artigo com um bom How to from Techspot (note que é para o XP, mas deve funcionar com o Vista):
So you have had that Windows XP or
2000 install working very nicley over
a year or more and it's only working
as good as it ever is going to get
with countless of tweaks and hundreds
of installed applications and updates,
all configured to your liking, next
you decide to buy a new/other
mainboard and start cyring over either
having to do a clean install (the
proper way) or a repair of your
Windows installation (resetting your
registry to default meaning most of
your apps and config changes will no
longer work...)
There is a better way, it's called
Sysprep. It's real use is in big
organizations where you can configure
a system the way it must be to be able
to work in your organization, then you
run sysprep and it removes the machine
specific drivers/settings allowing you
to make a Ghost image of the install
and push it out to thousands of
different machines which will all be
configured peoperly by the mini setup
that Sysprep configures the machines
to run on the next bootup... Well that
is the theory anyway :D
We will use it in a similar way, but
only on a single system...
1: Download all the latest drivers for
your system, especially remember the
LAN drivers since XP might not support
it by default and then it will be
difficult to download the rest of the
drivers when you have no net
connection ;)
2: Extract sysprep from your Windows
install CD, it is under
\support\tools\deploy.cab) to
c:\sysprep (it can also be downloaded
for XP
(http://www.microsoft.com/downloads/details.aspx?FamilyID=7a83123d-507b-4095-9d9d-0a195f7b5f69&DisplayLang=en)
or 2000
(http://www.microsoft.com/windows2000/downloads/tools/sysprep/default.asp).
3: Start Sysprep.exe choose
Mini-Setup, PnP, and then Reseal. Your
machine will shutdown when the process
is completed.
4: Install your new mainboard and any
other hardware, when you boot it up
Windows should launch a mini setup
wizard, similar to the normal 2000/XP
install... The setup should prompt you
for drivers it does not have, so lucky
you that you downloaded them in step 1
:D
Se isso não for para você, tente isto:
Você deve de fato desinstalar qualquer coisa específica da sua antiga placa-mãe, reduzindo as chances de um conflito.
A melhor coisa seria também desconectar qualquer hardware desnecessário, reduzindo a chance de falha.
Se você tiver um DVD de instalação, poderá fazer um reparo de inicialização e deixar que o Vista se ajuste ao novo hardware.
Talvez não se esqueça de fazer um backup, para que você possa sempre restaurar quando algo der errado.
Nota: Id sempre sugere para fazer uma instalação limpa quando você troca de hardware (especialmente sua placa-mãe). Talvez até mesmo uma solução melhor seria instalar o Windows 7 RC com a nova placa-mãe e tentar. Mas chega com a pregação e boa sorte! ; -)
