    85% RAM usage on idle, large cached memory.

    Hello, I've recently encountered a problem. It seems as if my computer is using way too much RAM for some reason. I currently have 6GB of RAM installed. As soon as I start my computer up, I'm greeted with this warning:

    So I decided to open up task manager and see exactly how much RAM I'm really using:

    No process is using up any amount of RAM to come close the above number. The most RAM using is 70mb or so from Google Chrome while typing this post. Clicking on the performance tab of task manager gives me this information:
    Click image for larger version

    I don't know what exactly is causing this problem, I haven't downloaded anything recently. I had this exact problem a few weeks ago and a system restore fixed it but I'm not wanting to wait on the computer to restore again or for this problem to just come back again. Any help would be appreciated, if you need any more information, let me know. I'm running Windows 8 on a Toshiba Satellite L875D-S7332.

    The real problem is the very high commit charge and that generally indicates a memory leak. Post a screenshot of Resource Monitor memory tab sorted by "Commit". Hopefully that will show where the problem lies.

    With 8Gb of RAM I usually have 3Gb Cached. And it's OK, since some of this memory is released for applications when needed. Since you claim no software is holding lots of RAM to itself, I can tell the next things:

    The Cached memory indicates the amount of physical memory used recently for system resources. This memory will remain in the cache in case the system resources are needed, BUT it's available should other operations need it. It's written to disk when not needed by Windows.

    Have you EVER used any Windows tweaker/optimizer or such? There's a tweak that prevents releasing system cache to disk "Prevent swapping kernel to disk". That kind of software usually has it. Ought to improve Windows performance, but recommended with lots of RAM. Maybe you have this registry value turned on and your cache always stays in memory even when applications need it and so on.

    1) Go to
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management in registry editor;
    2) Find the value called DisablePagingExecutive - it should be set to '0' for you;

    If you already got '0' there, we will have to think of smth else...
