Here is my REAL issue and why I an trying to figure out how to interpret what Task Manager, Performance is telling me about memory usage .
Each night at between 10:30 pm and 2:30 am, the cooling fan speed control kicks it up about 500 rpm. I go look at Task Manager and see a brief spike in CPU and a distinct drop in the CPU Usage History line graph. (see screenshots from two different nights
Note from the Uptime that the interval is almost exactly 24 hours)
I have searched various forums for the last week to try to understand what is going on.
I truly hope that someone here is wise and experience enough to explain this to me
