W7 high physical memory leakage, even idle

Microsoft Windows 7 home premium oem 64b...

Specs: Windows 7, 8G Ramm issue
computer scan was attempted did not work,
Manufacturer: Dell
Model: Studio 17, and similar seen on Vostro 3700 (32 B with 4G RAMM)
OS: windows 7, version 6.1 build 7600, 64 bit, updated to this very minute
CPU/Ram: 8G
Video Card: intel
Sound Card: don't know

Unit is leaking physical memory just siting idle for a few hours progressing from 30-50% to over 90%, sometimes progressing directly to a black screen. Task manager Physical memory reports 70-93% shortly before W7 alarms to shutdown a program to free memory, and machine locks to a black screen requiring hard boot sometimes a second hard boot to get control. However resource screen physical memory meter reports just 20-30% at the same time. Have run full Dell Diagnostics and have seen no issues reported. Today I captured a screen printjust running task manager showing task manager meter saying 73% of 8G of RAMM is consumed!

Commit Charge graph is showing nearly or at 100% as these events develop. Orange bar on memory usage is more than half the whole bar width. 4006 of 8192 installed. There is no explaination of Commit Charges in help or on MS website. MS WELL DONE AGAIN, please stay away from Yahoo, and adobe at least they still work OK!

I would scan for virus's, not sure if that could be a cause, but check it off the list. Then after I would try checking the memory sticks one by one and trying to narrow it down if a stick is dying. Could cause the problem.

This is clearly a memory leak, not a problem with RAM.
The Commit Charge is hard to describe but this more than anything else indicates a memory leak. Do a full malware scan.

If that doesn't reveal the problem then you will need to use Task Manager. Under the view menu there will be an option to select columns. Add the "Memory - Commit Size" column and monitor this for the highest users. Report these.

really appreciated these responses,

Have MacAfee and Trend Micro Internet security running already. Have not run malware yet, how about a suggest malware code I can run for you.

Have run HWINFO32 what can I give you from that?

Sum of commit in Process Explorer is just under 28GB. Have since increased Vitual to 50,000 when largest automatically managed was showing 21,XXX, But have not restarted yet, not sure if W7 vitrual increase needs a restart to become active.

Largest commit only 210,760KB see list sort below by the highest commit first below.

Thanks,

Had just installed MS Security Essentials, running full scan now. Judging from the progess it will take several hours.

Had rebooted started all normal websites opened then started Task manager Phy mem is just 37% , resource manager reports 30%, WHWINFO32 says 19% committ, physical 14%, with 4% mem commit. Turned resource monitor log on but did not see a acknowledging response.

Normal pattern is to see Task Man. version of Physical mem either heavily loaded >=90% in the morning or have a black screen. I'm betting it is a black screen. Going to let the MS SE do the scan and get me some rest.


MS SE found no threats,

Did you uninstall MacAfee, two anti-virus will fight each other....

MS SE found no threats, Process Explorer Current Commit grew to 12 GB from 7.4 GB at start of MS SE scan, Commit Charge 42%, own commit charge 4.9%, Physical Usage 39%, Own Physical usage 17%.

Machine has now set unused, but connected to internet websites for 8 hours. Process Explorer Current Commit grew to 28.5 GB from 12 GB 8 hours after MS SE scan finished, Commit Charge 92%, own commit charge 4.8%, Physical Usage 68%, Own Physical usage 18%. Physical usage volume is 5.1 GB. Physical Memory usage has increased 75% for 8 hours of no use other than internet connection and getting websites feeds. Task Manager reports Physical Memory at 68%, Resource Monitor reports 37% Used Physical Memory. Highest individual Commit is IE at 351,210 KB, MsMpEng second at 203,220.

This is a recently sold Dell Machine, that came with Trend Micro Shield (AV and firewall), Dell also recommended and sold McAfee to be added (not displace TMS), Memory leak symptoms was present before McAfee was installed. I have seen recommendations to install MS SE and did so yesterday and ran a full clean scan. This morning's 8 hour idle period with a 75% Physical Memory leak proves MS SE is not preventing the source of the problem. I had a period with just TMS, before even McAfee was installed that exhibited similar memory leakage. From this I am inferring these AVs are not the true isssue I am chasing. I'll uninstall McAfee.

Run time is not my issue, Normally the I5 CPU is at or below 10%

I have shutoff TMS and McAfee and left MSSE running.

'Have MacAfee and Trend Micro Internet security running already'
You cannot use 2 running AV's at a time, uninstall one or the other. If you uninstall McAfee be sure to use MCPR.exe from their website or there will still be remnants of it in the registry making it so that no other AV will work properly.

MS SE is really weak....why not go for avast free which IMHO is much better protection, especially real-time

Some HELP in posting on Computing.net plus free progs and instructions Cheers

Two biggest changes McAfee is uninstalled. TDS shutoff, website feeding Java Scriot charts to me was not active overnight. (yet I see two java plarforms still active in my task bar). McAfee was uninstalled using the recommended method. Have not found a viable means to uninstall TMS. MS SE is still active. Left the machine up and internet connected to a site using Adobe Flash over night.

Process Explorer Current Commit has grown from 28.5 GB to 49.5 GB, Commit Charge 92.4%, own commit charge 7.9%, Physical Usage 43%, Own Physical usage 23%, Physical usage volume is 3.4 GB.

Task manager reports Physical Memory usage has increased to 49 GB of 53 GB in about 16 hours 6 hours idled than internet connection, and the remainder actively used readingn websites. Task Manager reports Physical Memory at 44%,

Resource Monitor reports 39% Used Physical Memory. Highest individual Commit is IE at468,424KB, another IE at193,784 KB, MsMpEng second at 190,520. Commit Charge graph is almost at 100% ~93%

By 8PM 10/17 the task manager commit (GB) hit 56 /56, this screen flicked 10-15 then the machine locked up in a black screen and required a forced reboot to gain control. Yahoo email, two adobe flash session website and one java script graph were running when it hit the commit limitation. Had added most current Java today also.

That last commit memory overrun crash happened after McAfee was removed by using the recommended MSPR.exe.

Any further thoughts?

Massive Memory Leak On WLAN Card Driver (BCMWLTRY.EXE)

1. I have pinned about the 2.4 GB per hour memory leak to some kind of code problem within BCMWLTRY on a 64Bit OS Dell Studio 17 laptop. I strongly suspect the same problem occurs with wireless card within a 32 bit Dell Vostro. The cumulative page faults added by BCMWLTRY to the commit charges of a 64 bit OS will crash the computer when the accumulate exceeds the current sum of the RAMM plus vitual Memory allocation. You can delay thos crashes by increasing your virtual memory maximum size. I have not been able to Kill the BCMWLTRY program using MS Process Explorer, but have been able to suspend it. The BCMWLTRY will reemerge after Process explorer kills it. The composite commit charge accumulation average rate dropped to just 36,00 K per hour with BCMWLTRY suspended.
2. Now what do I lose if I delete this program?
This website confirms there has been a memory leak associate with this program since at least http://www.file.net/process/bcmwltr...

See this post:
http://www.computing.net/answers/cp...
Although it was CPU usage that was the problem on that one, you may inadvertently have committed your computer to be a part of a wide spread supercomputing project also. If you have traced it to a particular process, Google that name for more information on it and to see if it is something you can/should remove. If nothing helps, then you may want to back up your data and reload your system from your recovery partition to the way it was shipped from the factory. After you do this, install what you need, remove what they put on that you do not need, then create your own recovery disc so you can return easier to that same point if you ever need to again. Then replace you files.

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
