I have already checked this question on memory leaks. In that case, the guy had a huge non-paged memory and very little paged, which led everyone to the conclusion that he had a memory leak from one of his drivers. I don't know if that's the case for me.
In my case, I have a huge unjustified memory usage.
I have a total of 24GB of RAM that came preinstalled with my Asus ROG Strix laptop. All the time, there's like 22GB of RAM used out of these. I have no idea how this happens. The laptop was cleaned 3 months ago for dust, so it's probably not a dust problem.
Also, my SSD is not corrupted. I think I just don't have one.
My computer is really laggy as of recent and I really wonder why.
