Knowing you have XP, a activation via the phone should be no problem if you upgrade only.But is it worth it?
Before you look at the types of PC upgrades you might consider, it's important to think about which computers are worth upgrading. The best measure is the age of your PC. If your computer is less than two years old, it's a good candidate for upgrades. If your PC is much older than that, there's really no point in trying to upgrade it. PCs that are three, four, or more years old are simply unable to take advantage of the newest components such as hard drives or graphics cards.
