My memory usage gradually builds up over time until my computer shuts off. There are no known processes showing in Task Manager that would be taking up 7 GB of my 8 GB of RAM. I have updated all my drivers and done a virus scan, but the problem still continues. The memory resets when I restart my computer, but for some reason, is doesn't reset when I shut my computer off and turn it back on. I have screenshots of Task Manager if that in any way helps.
