Insane memory usage no showing in Task Manager

[mxoagentjohnson]

Last night i turned my pc on about 12am to keep some downloads going, couple steam downloads so no extra programs were added. I run 16GB DDR3 Kingston RAM, when i woke up an hour ago it had "Your pc is running out of memory" on a popup, only 7-8 hours of running idle download had i noticed 95%! of my memory was being used by seemingly nothing, and my MalwareBytes and Anti-Virus scan comes up completely clear, no issues atall.

I havent replicated the issue this morning after reboot, it seems fine now and i'm going out for a few hours so hopefully that gives it time to do it again if it will, but would a fresh install seem the best option right now?

cheers guys.

On W10? I do wonder whether W10 runs updates in the background with no outward indication at all that it's doing so.

Sorry man yea it was Win10, i7 4790k @ 4.5ghz, 16GB Kingston Hyper X, GTX 980ti Msi and a Msi Gaming 7 Mobo.

So far today, it seems fine, it's idling at 16% usage using just steam, mumble and chrome. I do need to fresh install soon anyway just to make sure drivers are ok y'know but i was so worried seeing 95% of 16gb being used without showing any processes exceeding 60mb at most

It was mentioned in another thread there is a service called SuperFetch which has a memory leak. Disable it to free up your RAM.

Any idea how i can do that, i couldnt actively find the source to it on Task Manager and this is the first time a situation like this has ever happened!
