When I first bought this desktop, after the prescribed amount of time of inactivity (it may be something like 15-20 minutes), the computer would go to sleep.

 

As I've used it more, I've added a few different software items here and there.  This computer is mainly used for school and leisure work, so there are no "heavy duty" programs on there.  Recently, however, I've noticed that the computer will continue to stay on and the fan running (or something is humming) all of the time.  Is there a way to check what program may be running that makes the computer think there is activity, when there is none?

 

Thanks in advance!

Go into powercfg.cpl and turn off the power saving for the monitor.
In short, tell it to leave the monitor on all of the time.

Then, when you leave it, open up Task Manager to the Processes tab - and click on the CPU column to sort by that

Then wait......

 

When you come back to it later on, you'll be able to see the processes that are running - and the most active (at that time) will be at the top of the list.

 

You can also check to see if powercfg.cpl has any changes that will allow the system to stay awake.

You can also check the Event Viewer to see any activity that's logged (go to it after the time that the system should have gone to sleep

Finally, you can log activity with Process Monitor (free from here:  https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx ) and you will see everything that's happening (beware, the log file is huge and complex).

Win 10 1511 updates are know for changing several configurations, inserting new Services. You have to stay on top of it with those people in Redmond.
