    Memory use shoots up to 99% after idle time

    I'm facing this problem in the last few days. Memory use according to Task Manager goes up to 99%, CPU reaches 80% and the PC becomes almost totally unresponsive.

    Based on similar threads I installed RAMMap and here's what is shown.

    I installed Poolmon and ran it and this is what I get.

    Please note that the first entry does not show a tag. Is this normal?

    According to the rest of the listing I should investigate Volsnap.sys and atc.sys. Could you advise what are the next steps?

    Memory usage 99% during idle and continues after reboot.


    My boot scan had nothing special to report and now my memory usage is normal. I know this will creep up on me again. This probably won't show anything in the error logs... right? Let me post what I found in event viewer.

    Why is my PC running idle at 99% memory?

    Bluetooth still on while idle

    Thanks for following the steps. Now, the settings won't take effect if you are only using normal PC idle mode. Normal functionality of Bluetooth and Wi-Fi settings are to stay connected even if PC is idle. With the settings that you have created, we would
    suggest that you set your PC to automatically go to Sleep or
    Hibernate     once idle. In this way, the settings "Allow the computer to turn off this device to save power" should take effect.

    To set your PC to automatically go to Sleep or Hibernate when idle, please follow these steps:

    • Open Control Panel, set view by: Small
      icons.
    • Look for Power Options.
    • Click on Change when the computer sleeps on the left pane.
    • Set a timer.

    Please try it out. Hope it helps. If you have any other concerns, don't hesitate to come back to us.
