RAM being used by nothing?

[ElliotGS]

I keep having this problem where in task manager it is saying i am using 4gb of ram when nothing is open, under users it says im using only 400mb but in performance it says 4gb is being used. In resource monitor when i sort by commit there is nothing on there that could possibly add up to 4gb. When i start playing a game that uses a lot of ram (KSP, BF4, Planetside 2) it skyrockets to 7.5gb and everything starts crashing.

 

I have looked into some other forum posts none of which have helped, so i was wondering if any of you know what the problem could be? any suggestions would be greatly appreciated.

 

PC specs:

i5 4670k @ 4.4ghz 

MSI z87-G45 gaming motherboard

8gb corsair vengeance pro

GTX 460 (used to have a GTX 770 but it did the exact same thing so i dont think it has anything to do with the graphics card)

120gb Samsung 840 EVO SSD

I have the same problem sometimes when I play bf4. I googled it but no solution, it is some kind of a memory leak.

Get msi onscreen display (part of afterburner) and allow the ram useage on the OSD and watch what it does, bf4 usually sit at 4gb on my system

last time i had high ram usage I was told to run an anti malware software and it deleted some threats and it went back to normal.

Uninstalled AVG and replaced it with malwarebytes, seems to have cleared up the problem.

This happened to me today when I was using Secure Download Manger to download software through Dreamspark. Used basically all RAM my laptop had, yet task manager showed nothing that would use that much RAM (Windows 7)

Enabled 'show processes from all users' ?
