I've read a million posts on this, none of which have aided me on the slightest. As seen here, my memory and disk usage are insanely high, with no discernible reason as to why. This is the case essentially all the time, and it's perplexing to say the least. In this screenshot, you can see what's troubling me about my memory usage. The system is acknowleging that I have 8.0 GB of RAM installed, yet is at a very high percentage with only 3.6 GB in use. Also, above the data graph, is shows that only 4GB of the RAM is in application, with 4GB of RAM being displayed at "Hardware Reserved" in the bottom right. I would adore some support on this issue as it's been plaguing me, and perhaps through resolving one of my issues I may resolve the other. Thank you!
