Windows 7: All my ram used all of a sudden.

All my ram used all of a sudden.

Hi all

I have a problem, my pc is in not way top notch anymore, but it should still hold its own . My problem is i keep getting something that uses up all my ram. Normally my system is running on like 20% of my max RAM, but sometimes something happens and all of the sudden my RAM skyrockets to 98%used and my pc lags as hell. It doesnt have to be that im in a game when tha lag starts, yesterday i was just browsing folders on my pc when i noticed it lagging, i looked at RAM used and what do you know 98% used. I have tried running bitdefender antivirus, spybot S&D, CClceaner but the problem is still remains. Anybody have any tips and trix on what i should do?

Thx in advance


My speccs are :

CPU : Intel i7 950
GPU : Ati Radeon 5870
Ram : Corsair 12Gb

Firstly I would uninstall SpyBot as Windows 7 does not require such Registry Cleaners.

Then Run SFC to check the integrity of all Windows 7 system files:

Click on the Start > Type in search cmd
Right click cmd at top and Run as Administrator
Type SFC /scannow at the prompt
(Note: there is a space between SFC and /scannow)

You could also try:
Free up the startup.
Click on the Start button
Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
Select the “Startup” tab.
Deselect all items other than the antivirus.
Apply > OK
Accept then restart.

Your Anti-Virus maybe hogging your resourses (Just a suggestion)

I would recommend MSE:

Microsoft Security Essentials.
Has better compatibility & stability compared to other antiviruses/internet security software.
Has a light footprint and is free.

Microsoft Security Essentials - Microsoft Windows

Uninstall all unnecessary programs that you no longer use.

Also Press Ctrl>Alt>Delete simultaneously and click Start Task Manager then choose the process tab.
Look under the memory column and it may give you a clue to what process is using the most RAM.

Hope that helps

Please post a screenshot of Resource Monitor (Memory tab):
  1. Start
  2. Type: Resource Monitor
  3. Accept UAC prompt (if prompted to do so)
  4. Memory tab
Here's my system to help show you what to screenshot;

The Memory Manager seems to be have a reserved the remaining amount of RAM for other processes, also FireFox is also using a large amount of RAM and is known to have Memory Leak problems, which I'm not completely sure if they have resolved in updates.

Please also post a screenshot of the list of Startup programs, which may be starting up at boot:
  1. Start
  2. Type: msconfig
  3. Startup
vsserv.exe is another problematic program, and seems to linked to Bullguard Internet Security and BitDefender Antivirus.

Yeah firefox is known to have memory problems, but it cant be the one reason to use all my 12gb ram. I have uninstalled bitdefender so the vsserv.exe isnt there anymore

Untick all the programs, is Spybot a scanner or a real-time protection program?

I find your definition of "... using a large amount of RAM ..." unusual.

My Firefox is currently using (41 open tabs):
  • Private Bytes: ~300 MB
  • Working Set: ~320 MB
  • Virtual Size: ~660 MB
If you want to see a browser using a large amount of RAM, check out what Chrome uses when it is running.

You'll need to take your screenshot when your RAM is being used up.
That shot seems to indicate that 9885 MB is "Available".

I'm confused about why a large amount has been cached for other processes which are inactive
