So my laptop has been performing pretty slowly lately, as I've downloaded some more intense editing and music programs for my computer. And I know one way to help it with multitasking and speed in general would be to upgrade its RAM. The thing I'm slightly concerned about (because I don't know enough in this area) is that I only have one slot for RAM. It's the 2GB that my computer runs on. Would I be able to simply replace that with an 8GB RAM? My computer says it can go up to 8GB, but I'm just not sure if I can replace the existing 2GB - or does there have to be another slot to add new RAM to? Any answers would be much appreciated
