Had to RMA a motherboard for my dads computer. Vista (home premium) is installed on the harddrive. Should I erase the hardrive before re-installing Vista or just re-install over everything. Data loss isn't a problem I've already backed up everything I need to a USB drive. I'm just looking for the proper way to go about re-installling Vista after replacing the mobo. If I should erase the hard-drive could someone give me a few pointers on the proper way to go about doing that. Thanks!
