That really depends on what you have ... and what you buy.
If you can "match" what you are buying with your existing ram, you should have no problems whatsoever. However, most people have bought their PC from Comcrap, Hewlet Crapard, Dell Hell or some othe proprioty manufactured PC ... they fit what works and unless you use someone like Crucial to 'match' it, you'll no doubt end up in misery.
XP is also very picky at what you have as is your MB ... I have been spouting the numbers game for years.
Everything to do with computers is 'critical' and one 'cheap' component can give you a crap load of bother.
Your brother was probably playing safe ...
or does not know any better ... but in general, it is better to replace the old with the new. As long as it is the correct type for your MB.
