I have 20GB of ram (they are mismatched) on a prebuilt running a rx 580 Ryzen 1700 and games that i can normally run 60 fps fine on high such as dbd are running chunky and laggy as hell on low. Half my ram is being used when discord and brave(browser) are the only things open. Therese also a million server host using ram and Antimalware service executable and Malwarebytes (minimized)_ are constaley using 300MB min when both Malwarebytes and windows defender says that there is no virus idk what to do I tried restarting closing programs stop startups and i can't find anything online that seems to fix the issue.
