This may seem like a noob question but i was wondering if i will need to replace windows if i get i new motherboard. My computer is a HP workstation and it came with windows XP professional.
since i already have it on my hard drive will it just not boot with a different motherboard?
Some will boot with no problem, some won't. If it doesn't boot, you can use your OS disc to boot into the repair console and repair the install.
I always recommend doing a fresh install when changing out mobos. You can start getting into driver conflicts and flaky issues. You can back up your data, format, fresh install, and it'll wipe out all the cobwebs for your new board.
