I've never added RAM to my desktop PC yet. It has an Intel e5700 processor, and currently has 2GB of DDR3 RAM. Also it is 32-bit Windows 7.
Am I right in thinking I can just buy some extra RAM, say an extra 2GB, or 4GB and open up the PC and slide the RAM card into the correct slot, boot up the machine and then I have a faster, sleeker machine? Sounds too easy.
