You remove the existing RAM modules and put new ones in their place, taking care to choose modules that are compatible with your motherboard. Memory manufacturers like Crucial have 'RAM finder' tools on their web sites.

You check on the manufacturer's web site.

If your use of 'lately' means it used to run faster at some earlier time, then extra RAM probably won't make it go faster. You may have a virus or too many programs running in the background.
