I cant understand whats happening with my ram. I have only 1 google chrome tab open and I've tried reinstalling it and i have like 99% memory usage? I just tried to play arkham knight (A game that used to run perfectly at 60 fps around 6 months ago now runs at about 45 and has awful frame shudders. I've linked three photos of my memory going down the list. Is this a memory leak, a virus, or just old age?
