RAM slots are full

[Jagfan]

I planned on adding more RAM to my computer, but when I opened the casing, I saw that all three slots had cards in them.  The smallest had a 128MB card.  Can I safely transfer all memory to the first two cards so I can remove the third and add one with more MB's?

No.
You possibly can replace smaller capacity RAM modules with bigger ones. It all depends on your motherboard.
Go to www.crucial.com, enter your computer brand, and model, and it'll tell you.

Thanks for the replies.  Through more research, I learned that when the computer is off, I can swap the secondary cards out for larger ones.  Nothing is actually stored in the cards.
