I had the same problem and was the "virtual memory" ( i call it page file or swap file.... ).
Try this commad in to powershell if the value is lower than 16256 you didn't set it correctly.

Command:
Get-WMIObject Win32_PageFileSetting


Output example:
PS C:\Users\admin> Get-WMIObject Win32_PageFileSetting

MaximumSize Name            Caption
----------- ----            -------
      16256 c:\pagefile.sys c:\ 'pagefile.sys'
