..mm...Easy?...yes it is simply a matter of removing the cover from your pc and plugging in more memory modules (ram)....that physical action is so simple, that any one could do it...BUT from you question alone I infer that you know absolutely nothing about computers and might have some difficulty identifying a few things, such as how much more ram your mother board will take...what kind of ram (there are different types).......and a few other important bits of knowledge you will need like where to plug it...........In your case I would either contact a knowledgeable friend or pop down to your local PC specialist and get them to do it for you................It will certainly make a big difference to your computer, and well worth the effort.....commoner.
