I'm having a bit of a problem where all of my RAM is getting eaten away by something i don't know.
I have noticed that when i start some programs the RAM Just keep going away but when i then look in task manager or Resource Monitor there is nothing taking up that much RAM.
It would also be helpful if you would show all the programs, or click the top of the memory columns and allow them to sort by most usage. You are looking for some program that uses more than normal, unless you are running many programs not displayed on your attachment.
FYI, you can use the Snipping Tool to take a picture/s of an exact part of your desktop, or Alt+PrntScreen to take a picture of the active window. Just in case it might help.
