Windows 8.1 computer low on memory, casuing MS Office and Firefefox problems

I have a desktop running Windows 8.1 that is starting to run low on memory at times. I've attached a popup I get at times saying "Close programs to prevent information loss" (attached screenshot).

When the system gets low on memory, Firefox often crashes.

Other problems is if I have some MS Office windows open, then will go blank and I will have to close and re-open them, losing any changes I have made since last saved.


I have attached what my task manager looks like while having several Firefox windows open and MS Outlook open. Any idea why my system is running so low on memory at times?


My Computer has:
Windows 8.1 OS
64 bit Operating System x64 based processor
Intel i7-3770 CPU @ 3.4GHz
8.0GB of RAM
C Drive has 250GB Solid State Drive
D Drive has 500GB Hard Drive
(Firefox v37.01)

I can't view your screenshots because it says the files have errors.

However, the first thing I'd suspect is malware. Open up Windows Defender from the Control Panel and run a full scan to see if it picks up anything.

I'd suggest that you use multiple tabs but don't use multiple windows in Firefox.

Select the "Don't load tabs until selected" option to reduce Firefox memory consumption.

I strongly recommend that you use the Session Manager Firefox addon,
to ensure graceful recovery from crashes.

i cant see your pics, but barring any type of malware, i would aim at firefox plugins/extensions.  If you load up too many extensions in the browsers, it really eats the hell out of your memory. Remember, every tab and every window loads up every plugin you have in the browser.  
So the first thing i would do is disable any FF plugins & extensions that are not completely necessary and start working like normal.  
see if you get crashes or memory leaks.  then, 1 by 1, start enabling them, from the most reliable to the "hey, wtf is that plugin and when did that get installed"
In my world, its chrome that is the huge memory pig.  I have my firefox very clean with just uBlock and roboform, whereas my chrome has every plugin on the planet.

In Firefox try ...
Help > Restart With Add-ons Disabled

Then compare memory usage

Check your pagefile settings. Set a system managed pagefile on your conventional disk if there is none there.

Oops, not sure why the images didn't show. here they are.

"Don't load tabs" is already enabled in Firefox
I'll try the Session Manager add-on in Firefox

You are using an outdated version of Adobe Flash player and need to update it. See the version list here - http://www.adobe.com/software/flash/about/

This can cause the plugin container to crash. A lot of ad content (which often uses Flash) on pages can also make FF crash. You may want to look into install AdBlock for FF to filter some of that stuff out.

I updated my Flash Player.

I also have the results of my full Windows Defender scan. Defender found two threats. One with the alert level Severe named "BrowserModifier:Win32/DefaultTab".

I attached a screen shot.

I had Defender remove both threats.

Uhhh yeah those two things will definitely cause a problem.

You should now install Malwarebytes and run a full scan, too. It tends to pick up more stuff that Defender can. http://www.malwarebytes.org/mwb-download/confirm/

You also need to update your version of Java (via Control Panel - java)

Updated Java

Downloaded and ran Malwarebytes. It found 13 threats and removed them.


Thanks for all the help so far. Should I do anything else?

if you find you are still leaking memory after updating flash, double check all of your firefox extensions and plugins and make sure they are 100% necessary for your day to day browsing.  disable anything not needed and go from there.

Also, if you use ADBLOCK, i've read that the last few versions have a pretty bad ram leak and you may want to investigate using uBlock instead.

if you find you are using flash heavy sites pretty often, you may want to use chrome with its built in/auto-updating flash interpreter.

As an aside, MALWAREBYTES is TOTALLY worth the money for the premium version.  its been the most stable consistent spy/malware catcher for at least 6 years now.

After following many of the suggestions from this thread, I have attached a screen shot of what my current system looks like.

This is with Outlook running as well as several Firefox windows/tabs (3 Firefox windows with 4 or 5 tabs in each and a Microsoft Silverlight video playing).

Does this look about right, or should I do anything else to try to clean up my system


Thanks for all the help!

It looks OK. I see you got three browser windows open. What's on them? Any large animated ads?

very nice. Firefox is using half of what it was using before. now the trick is to keep it that way. make sure to check up on memory usage a few times throughout the day over the next few days to make sure there aren't any huge leaps in ram usage.  if you see Firefox starting to encroach and not releasing ram,  you may have an extension that's leaking.
