Upgrade without OS reinstall?

I'm upgrading my wife's computer - motherboard, processor, memory, and
video card.
OS is Windows 7 Pro 64. Old motherboard is ASUS M3A with DDR2, processor
was dual core
going to quad with DDR3 memory. Video card was GeForce 9800 going to
Geforce 465GX.
Will I need to reinstall the OS or can I just remove the IDE controller
and install the new driver
after the hardware change? Will Windows allow it, or is that too much
hardware and Windows
will detect it as a new computer requiring install and registration?

Thanks

OS has to reinstalled... I used old OS and never registered no matter
how many I reinstalled OS. I think new OS like Windows 7 came with
very strong security issue that user has to re-registered again and
again. I'm sure new OS comes with more security issue thing.. For
example, I don't like the latest WMP version comes with manditory
registering issue so I never used that one. I don't even like running
any virus program slowing down
the computer...
