Thought some of you computer experts on here might be able to help me a little bit. Previously got some advice from some of you re my computer memory and it finally came today. Somebody said I should replace the original one and put it in the second slot. Unfortunately when I did this it didn't seem to work. However, I've put the new one in the second slot and it appears to have picked it up. Is this ok or should I try swapping them about again.
