    Bizarre Monitor/system freeze issue


    I'm not sure where to post this so I thought I'd start here. As part of my office network of 4 computers I have a 2013 basic Compaq desktop computer that I upgraded to Windows 10. This computer remains on all the time and I sometimes remote into the computer using Teamviewer. About once a week the computer will disappear from Teamviewer as if it was shut down. The computer is still on but the screen is blank and neither the screen nor the computer will wake up as if it was in a sleep or hibernate state.

    Now here's the bizarre part: if I unplug the power cord from the monitor and plug the cord back in, the monitor turns on and the windows login screen immediately appears. I can login and it looks like the computer is starting up again even though it wasn't shut down before.

    Any ideas? I don't even know where to start.

    I should also mention that one of the other computers in the network exhibits similar behavior. That desktop computer is a Vista computer. With that one, the computer really is frozen and I need to do a hard reset. After doing the hard reset chkdsk runs and checks the disk for errors.

    The one and only common thing between these computers is that both computers use a USB-Wifi adapter for connection to the wireless network. I have turned off USB selective suspend if that makes any difference.

    From your first post I would suspect that there is something not right with the energy saving behaviour between the monitor and graphics card or on-board graphics. What sort of connection do you have HDMI or DVI or the older VGA? How have you set up the power management in W10? Just my first thoughts to get some ideas rolling. :)

    Thanks for the reply. The monitor is connected with VGA. I have set the power management to always be on. It is set to never sleep or hibernate. The screen timeout setting is 10min with a password required and that works most of the time, but as I said the blank screen/power issue happens about once a week or so.

    The computer has an AMD processor with Radeon graphics.
