I just upgraded my duel core to a higher deul core and all I had to do
was flash the bios on my motherboard to accept teh new cpu. For ASUS
motherboards, it was a snap. Get up with you motherboaqrd manufacturere
and see what they have to say.

Good luck!

Going from a dual core CPU to a quad on the same motherboard
does not require a reinstall as Windows already has a multiprocessor
hardware abstraction layer (HAL) installed. The requirement for a
repair or full reinstall occurs when going from a uniprocessor HAL
to a multiprocessor HAL to support upgrading from a single core CPU
to a multicore CPU.

The only exception is when upgrading from a single core P4 with
HT to a multicore CPU, because a multiprocessor HAL would
already be installed for the HT.

Thanks for the detailed explanation. Do you know if it's possible to
"repair" Vista so it would install the multiprocessor HAL? Vista doesn't
have a repair/install option like XP as far as I know. I wonder if it would
detect the change from a single to dual core, or just treat it like a single
core CPU? TIA
