High CPU usage when computer is not being used.
Sometimes when I wake up in the morning, the fan on my CPU is going full blast on my Dell Optiplex 780. This tells me that the CPU is being maxed out. However, I never get to see what process is causing the overload because by the time I turn on my monitor and move the mouse, the computer immediately calms down, every time this happens. If I am quick enough, I can see in the task manager that 50% - 70% of the CPU is being used and it drops to zero in just seconds—too quick to see what process it was. I am sure it was 100% CPU before I moved my mouse.
This problem does not happen a whole lot, just enough to raise some concern.
Does anybody know what the problem could be?
