I've recently been looking into upgrading my computer, because it seems a waste to buy a new one when this one is only 2 years old and only really lacks RAM. Note that this is my first time planning something like this, but my father, who tinkered for years before settling on one computer, is there if I need him.
That being said, I've found conflicting information as to how much RAM my computer currently has. It is a Compaq Presario SR1603WM and the properties say it has 222 (or so, it's shut down right now so I can't double check) while the model specs say it has 256. My father suggested I open it and look at it, but I'd rather not if I don't have to, as it would be a hasle to do with its current placement.
