Ram

I have an older computer (Alienware 17r3) it has 8 gigs of ram which is pretty decent still and the rest of the hardware seems to work "okay" with modern games or whatever too. However, recently i've noticed that I will do literally anything and my ram freaks out. What I mean by that is im watching youtube and it uses 90% of my ram. or like right now i have this google tab open, discord, and steam and its using 50% of my memory. Anyone have any suggestions that doesn't require a factory wipe?
