Low Memory warning troubleshooting

Emachines EL1352G

I just recently started getting low memory warnings when the computer is not being used. It just pops up and I have to reboot several times to make it run again. I ran the memory check tool and it found no problems. I try to open task manager when its acting up but it just won't cooperate. Are there any good tools to see whats dumping my memory?

So this memory problem pops up when the PC is sitting idle, and then you can't open Task Manager, right?

If so, Try this:
Open Task Manager / Processes tab
Click on Show processes from all users
Sort the list by Memory (Private Working Set) so the highest numbers are at the top of the list (Descending).

To Sort by a column in Task Manager, click on the Column Heading.
Each time you click the heading it will toggle the sort order from ascending to descending.

Now, leave the TM window open and displayed, and let the PC idle to get the Memory popup.
When you get the Memory popup, can you see what program(s) are using so much memory?
Hopefully whatever program(s) are causing your issue will be listed with a HIGH amount of memory at the top of the list.

If you can capture and post a screen print when this happens, that would be great.
If you can't capture and save a screen print, write down the Image Name and Memory amount, and post that info.

Here is an example of what I am trying to explain you want to see

I was able to make the suggested change for page file. Now I don't get the error message but computer is unusable. I can't even get task manager to open. It says unable to open security and task manager. If I open ie it takes a good 3-5 minutes for page to open. I'm baffled.

If this is still the eMachines factory preinstalled WIn7 that is an inferior install larded with bloatware and useless duplicate utilties which interfere with better versions built into WIn7. So I'd do what most tech enthusiasts do and Clean Reinstall - Factory OEM Windows 7 following the steps in blue link tutorial to get it perfect.


Otherwise boot into System Recovery Options to run Startup Repair. If it doesn't offer to System Restore, then choose it from the Options List and work backward until you find a working configuration. But if it's still the factory install then you still have the worst possible install of Win7, so I'd go with the reinstall since we're here to help you.

Ok, I finally got into task manager and the hog is (coreserviceshell.exe). It's using 10,599,253 by itself. I googled it and it seems to be related some how to my Trend Micro Titanium anti virus.

That's great you found the process causing the issue!
When I Google coreserviceshell.exe I see some hits where other folks have performance problems with this.
Here is one Trend Micro article about CPU/Mem issues:
[Hot Fix] B1181 - My computer slows down and CoreServiceShell.exe consumes high CPU usage after installing Titanium 2011
I don't know what version of TM you're using, so that hotfix may not help you...

You should post your issue on the Trend Micro support forum and see if they have a fix for your TM Version/issue...

You could also consider switching to a different AV product...

Use Microsoft Security Essentials.

All of the tools and methods which work best for Win7 are in the Clean Reinstall tutorial.
