Hello, I built a new computer about a month ago and recently it has been having a huge memory leak. I've attached a few pictures that show what I am talking about. I decided to do a bit of research on what I can do in order to find out what is causing the memory leak. I read online to download the Windows Driver Kit and use poolmon. I've attached a snapshot of poolmon that shows the tag "Thre" using the most Non-paged pool memory. "Thre" apparently is the tag for "Thread objects" and I don't know what that is. Running the findstr command returns basically every .sys file. I'm not really sure where to go from here and I think I'm a bit out of my depth. Any help would be greatly appreciated. :)

Edit Here are my specs:
Mobo: asus x570 tuf gaming plus
GPU: RX 5700
CPU: Ryzen 7 3700x
RAM: G.Skill Trident Z 3200 16 gig

usually is because win 10 isn't off when you turn it off, its in a hibernate mode. So if its a driver memory leak, its clearly not releasing the ram on startup

can you download and run driver view - all it does is looks at loaded drivers. it might show old drivers that could be cause - http://www.nirsoft.net/utils/driverview.html
when you run it, go into view menu and set it to hide all Microsoft drivers as will make list shorter.
Can you take a screenshot showing all the columns from (and including) Driver name and ending (and including) Creation date - upload to same place as other shots.
It might give us a clue as to what is old. Older drivers more likely to be problems than new

Your motherboard doesn't use killer internet drivers or my life would be easier. They known to cause this... yours has Realtek instead. Given every driver on motherboard is 2019 it might be a fun search.

I would suggest Resource monitor but you can see usage is showing as Firefox. So it might not prove anything. Could also try Process explorer - 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 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 don't know how to decypher poolmon screens as from memory you use that info to figure out which process is to blame - this might help or might be too much info

what are specs of the PC? what motherboard do you have?

memory leaks can often be caused by drivers, if its in Firefox I would guess it could be LAN drivers.

Does ram come back on a restart? Does it slowly increase or always same use?

Hi, thanks for the reply, sometimes the ram comes back after the restart and slowly increases. However, usually it stays around 12 gigs of non-paged as soon as it starts. I updated my main post with the PC specs.
