Well since I am having the USB problem with my current PC I plan to swap them and use the new computer in mines place. I am just hoping it is at least as good as my old pc...maybe a little better.

If I was to take the big hard drive out of my old PC and put it in the new PC will I still be able to use the Windows version that is on the old hard drive? If I ever have to reformat it will XP know that the hard drive was in another computer and give me problems?
