Crazy high RAM usage out of nowhere

[Zarok Aleon]

So I have windows 10 and lately I have noticed very high ram usage, I thought it was just games and stuff but I shut my pc down and rebooted it and it is still using 95+ percent constantly. I have no games open, I have 16GB of ram in the system, and when I open task manager chrome is using like 500MB and then a bunch of other things but nothing is using enough ram, yet it still shows 95% even though nothing is listed that uses that much. CPU usage doesn't go over 15 usually. For some reason it is showing alot of ram used even though there are no processes using near that amount.

What could be going on and how could I fix it?

Press Start+R, type in "resmon.exe". This will start Resource Monitor. Go to the memory tab and sort processes by clicking on the "Commit (KB)" Column above. Check if any specific process is taking too much RAM.

Generally, svchost.exe can take up a lot of RAM due to specific services. State which process is it.
(Resource Monitor as Task Manager doesn't list all processes)

memory to windows means more than ram, it also includes page file usage.

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. Sort the columns by either of the two columns mentioned next:

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.

you might have a memory leak from a driver - it may have requested ram and never released it once it was finished.

Since creators edition, the services listed in task manager have been unpacked so whereas before you had 20 odd service hosts, you likely to have anything up to 70 now but it means you may be able to use it to identify whats using all the ram.
