Hi I'm useless at this stuff and admittedly looking to leach on some knowledge but I can't for the life of me figure out what's wrong with my memory after playing a few games. I have 16GB ram and a quick google search said Windows shouldn't use nearly as much as I'm missing. For the record I'd been on Firefox and the games Diablo 4 and Baldurs Gate 3 exclusively and after some time the computer just gets dumb slow, to the point where even task manager is having trouble. ANY help appreciated. A restart fixes it but I'd like to know what's going on.
Here are some screenshots of my limited diagnostics
