Hello everyone,

I need some serious help; I've had some issues for the past month or so, I've had a fairly large memory leak with something in my system. I can't figure out what is causing this, be it a program or a driver.

Is there a way to see what is causing this mass memory leak? I've tried 'System Explorer' and 'RAMMap'. But these do nothing more than assertain the memory leak has no source.

Did you check your ram? Try checking it with MemTest86

Just did, 0 Errors. Took about 1.5 hours to complete. This is normal right?

It's a gradual thing, the memory keeps filling up and gets to about 11 gigs of occupied ram in about 2 days worth of use. Sometimes less. A restart normally does the trick with clearing it.

It seems like Mozilla Firefox is taking the most of your RAM, and I've seen a lot of issues in the past that were associating Firefox with memory leaks. The best would be for you to take a screenshot of your Task Manager, under the Process and click once on the Memory column when the memory usage reaches around 11GB like you say. This way, we could really see which process(es) is(are) using the most RAM. Also, make sure to have Show processes for all users checked as well.

- Did you recently update one or more drivers ? The fact that "Svchost.exe" occupies so much memory (~ 300 MB) seems to point in that direction.

- What's the size of the filecache ? (That doesn't show up in Task Manager).

- Does this thread give you a better clue what to look for ?

I ran my PC today without using Mozilla at all, same thing. Played my games as usual and held back from browsing the internet outside of that needed for my school work.

Here's a couple screens.

Looked through this, I have a similar problem, but I'm not running window 8.1, rather, I'm currently using windows 7 and the problem although similar does not have the same solution. Or at least one that i could find.

By any chance is there a program or function in Windows that allows me to monitor what is paging all this ram?

Run RAMMAP again and open the tab "User counts". What's the size of the "Non Paged Pool" ? If that part of the memory is VERY large in size then I point my finger to some (network) driver. Was one of your drivers updated in january (Windows Update ?) ? Your description of the problem seems to suggest that.

 

The solution for this problem ( in the thread I provided) was to tweak the registry but then you have to go to the website of the manufacturer (helpforum ?) or perhaps a GOOGLE search will give a clue what tweak to apply. (I hope you know how to use the Windows Registry Editor).

Finally found the problem and the solution. Sorry I didn't post till now, I had given up all hope prior to solving the problem and lost track of the forum.

The cause of this was a self installed rootkit. As far as I know there were not intrusions into my computer.

This could have been a bit-coin miner for all I know. Malwarebytes was not detecting this until I specifically made it scan for rootkits... Which I find weird that it is not an automatic search.

Scan for rootkits isn't enabled by default in Malwarebytes, since it increase by quite a lot the scan, hence why. Well glad that you found the problem and fixed it too :)
