Hi i'm currently using dell studio xps435mt with this mobo http://compare.ebay.com/like/270759092439?var=lv<yp=AllFixedPriceItemTypes&var=sbar, running window 7 32bit with 640gb hdd , cpu is i7 920 lga 1366 x58 , i wonder if i want to upgrade the motherboard to like let say msi big bang x58 xpower, do i have to uninstall current window then plug the new mobo in then reinstall it or it will work without doing anything?
