I bought this desktop years ago and I have never enjoyed using it because it absolutely REFUSES to go to sleep. It won't sleep on its own despite requests to sleep after a short period of inactivity. It won't sleep when I tell it directly to sleep. it won't sleep when it is on the sign on screen and I tell it to sleep. 

If I am lucky enough to get it to enter sleep, after telling it to go down three times, I almost always return to the sign on screen awake and asking me to sign in.

I feel like I should be on a mommy forum here with a temperamental toddler!

It has happened since the day I got it. I've upgraded and updated and I'm now running windows 10 and it is still happening. I could really use some suggestions.
