Task Manager says I'm using more RAM than the sum of all my processes?

Task Manager says I'm using way more RAM than the sum of all the processes it displays! If you add up every task in my list it's 3GB with a VERY generous estimation, yet it says I'm using 76% of my 16GB, what could be taking up so much memory?

It could be a memory leak caused by a driver not releasing memory after its used it

Download Process explorer and run it as admin (it comes from Microsoft so its safe)

the default view is tree structure meaning like your task manager screen, it will show what processes are under each service, but unlike task manager, it shows the ram usage of each part so you can see what is eating your ram

Private bytes = actual ram usage
Working set = Ram + page file usage << this might be the column you need to look at

This page shows what all the colours and headings mean, link at bottom of it shows how to use it to find problems. You can right click headers and run an av scan from within the program.

i tried that, and although it shows much more, it still doesn't come anywhere near the 13GB it claims are being used.

what are specs of PC? Its likely to be a memory leak of some kind.

Does motherboard use Killer LAN drivers? If so, see if updating the drivers fixes it - this is just a guess as Killer drivers are well known for memory leaks.

Yes, actually it does use Killer LAN. I updated the drivers a few days ago for an unrelated reason, and didn't even think to check my RAM usage, and sure enough the issue is completely gone! Thanks for the help!
