[WIN7] STOP: 0x00000050 BSOD in Windows 7 64bit

I looked over at the laptop and saw a BSOD:

PAGE FAULT IN NON PAGED AREA

STOP; 0x00000050 (0x000000002E6000000, 0x0000000000000000, 0xFFFFF80002CF8D48. 0x0000000000000008)

Collecting data for crash dump
initializing disk for crash dump
beginning dump of physical memory
dumping physical memory to disk: 100

Meanwhile the only minidump and MEMORY dumps I have are one from March 2012.

I changed the debugging info to "small memory dump" (256K) and it now shows that it should go to %systemroot%\minidump. I don't have it set to "overwrite".

This BSOD occurred out of nowhere and we didn't restart the computer.

I recently d/l and installed the latest display driver which I got from Lenovo. It seemed to go well. I did this on 8-5-12.

On 8-1-12 Windows said one of my disks had to be checked for inconsistencies and CHKDSK checked the disk and found free space and fixed it.

I found two hotfixes for Windows 7 for a STOP; 0x00000050 error.

One is KB951418 »support.microsoft.com/kb/951418 that says it's for a timing issue in Server service driver. timing issues involve new SMB session. Server service synchronizes these operations incorrectly.

The other is KB976527 »support.microsoft.com/kb/976527 that says it's about a TCPIP system driver.

I have no idea if either of these Hotfixes would fix my computer.

Is there a way to find out what's wrong and how to fix it? Is there anything specific I can look for in Event Viewer?

Thanks for any help.

Sincerely, Libra

Re: [WIN7] STOP: 0x00000050 BSOD- ANOTHER BSOD

I just did Windows Updates and installed a new Flash yesterday. Everything seemed fine.

This morning we got another BSOD. This one is a BAD POOL CALLER

I got a dump file and I copied (from BlueScreenViewer.exe) the first line from the top and the first two lines from the bottom pane:

081712-20763-01.dmp 8/17/2012 9:36:13 AM BAD_POOL_CALLER 0x000000c2 00000000`00000007 00000000`0000109b 00000000`00000000 fffff8a0`088790c0 monitor.sys monitor.sys+32b80c0 x64 ntoskrnl.exe+7f1c0 C:\windows\Minidump\081712-20763-01.dmp 4 15 7601 319,238

Can anyone please help me with this? I don't know how to get the complete dump file here or all of the contents from the Blue Screen viewer - I just copied one line at a time.

It seems to be pointing to monitor.sys - what is that?

This is two BSODs in 3 days!

Re: [WIN7] STOP: 0x00000050 BSOD in Windows 7 64bit

monitor.sys is the class driver for monitors i.e., display devices.

Since I'm a suspicious guy, I'd consider blaming the display driver itself.

Contents of Intel Driver folder
Thanks Dave. I just updated the display driver on August 5, 2012 hoping to stop the black screen when the laptop came out of hybernation. I downloaded the file from the Lenovo site (it's the Intel Onboard Graphics Driver 8.15.10.2342) All over their site they say to use the driver they provide. Anyway I downloaded the file and just double-clicked on it to install it (I didn't remove anything). It seemed like the install went well.

Should I download another copy of this file and install it on top of itself? I noticed I now seem to have that file in C:Drivers.

I have no idea of what happened to the original driver I had (8.15.10.2246)

If I should re-download it, should i delete the Intel driver in my C:Drivers folder? Here's a screenshot of what's in that folder.

Sincerely, Libra

Can you zip up and attach the minidump files in the C:\windows\Minidump folder to a post in this thread?

Minidump files
Hi auggy,

I copied the 8/17/12 dmp file and zipped it. Then I dragged the 3/28/12 dmp file into the zipped folder (since that BSOD is very similar to one of the BSODs I got this week that Windows didn't make a dump file for). If you don't get the 3/28/12 file let me know and I'll attach it separately.

Thank you for looking at it.

Sincerely, Libra

The errors may be graphics related.

In the earlier error the process that crashed was the igfxsrvc.exe which is related to the Intel graphics.

With the later error there may have been involvement of the monitor.sys (Monitor Driver).

What Lenova laptop do you have (model)?

Have you checked the RAM with a memory tester such as Windows Memory Diagnostic?

Hi auggy,

I forgot to mention something. The 3/28/12 dump is very similar to the August 13, 2012 BSOD (they are both PAGE FAULT IN NON PAGED AREA).

Since that 3/28/12 error I updated the Video driver to version 8.15.10.2342 dated March 29, 2011 (I got that from the Lenovo site, but it showed a different date - this date is in my device manager). I did this because occasionally the computer would come out of hibernate and be running, but the display would be black and I had to do a hard shutdown to get it to come on.

I have the Lenovo G570 (4334).

I called Lenovo Friday and they remotely took over the computer and used the Windows Memory Diagnostic and it said the memory was fine. He also set chkdsk to scan for and attempt recovery of bad sectors and that said "no problems were found on the device or disk". He said the computer seems to be running fine and to call if any more problems/BSODs.

The only other driver I have updated on this computer is the Lenovo Energy Management to version 6.0.3.0. That was because when I used "switch user" the Energy Management of the disconnected user was using 25% CPU. The new driver fixed it, but when I got a BSOD on 6/25/12 REGISTRY_ERROR STOP:0x00000051 I noticed that problem sometimes comes back.

Thank you again for looking at this.

Sincerely, Libra

You're welcome for the help.

One driver that may be problematic is the WDMirror.sys.

The WDMirror.sys, which is dated Jun 17, 2008, is the "Lenovo RMCT Display Driver".

You may be able to update this driver by installing the following:

»support.lenovo.com/en_US/downloa···DS007897

I would also suggest to update the card reader driver:

»support.lenovo.com/en_US/downloa···DS011342

There also appears to be a remnant of a previous McAfee installation and that is the mcupdate.dll.

You could consider running the following removal tool from McAfee (create a System Restore Point first):

»service.mcafee.com/FAQDocument.a···TS101331

Hopefully the blue screen errors are over but if the error reoccurs please provide the resulting minidump file(s).

Thank you. I updated both drivers (they each required a reboot) after the ReadyComm driver it booted in 29 seconds! After the Realtek USB it booted in 44 seconds and after using the McAfee removal tool it booted in 43 seconds.

After each it said it was successful! Afterwards I looked in the Event Viewer and saw two errors (which I have been seeing a lot - regarding Windows Search Service terminated and Faulting Application; search indexer.exe - module ESENT.dll. I'll copy them here. Do I have to be concerned about them?

Those application errors would indicate an issue with Windows Search and the issue could be from third party software.

When did the errors start and did the start of the errors coincide with any software change?

Hi auggy,

Although I have found some Windows search errors (that said it happened 30+ times) I didn't find as many as I thought. I did, however, find many Load Perf errors that started on February 24, 2012 and continue to this day. It also happens that on February 24 when we woke the computer from hibernation the computer turned on but the display didn't. I had to do a hard shutdown and turn it on again to get the display. That's happened at least 3 times. I have no idea if that could be related. Here's those errors:

I also noticed a few application errors for Svchost.exe_sys.main that started on February 20, which happens to be 4 days after I got the computer back from service and they reloaded the OS at that time and updated the bios.

Thanks auggy.

I don't believe those errors would be directly related to the display not turning on.

You can choose to ignore the errors or you could try what is suggested in the following link which is for Windows Server 2008 but should also apply to Windows 7 (Rebuild the list of available counters):

»technet.microsoft.com/en-us/libr···10).aspx

Also, can you check here?:

Start > Control Panel > System and Security > System > Performance Information and Tools > Advanced tools

In the Advanced tools, under "Performance issues" are there any issues reported?

If so, can you click these links for more info.

Hi auggy,

The first time I looked at the Performance issues (from a standard user account) the results were weird. It showed (l) a tv something which I think referred to my disabling the driver for the Lenovo camera, and also said (2) to restart a service. It also said Windows couldn't find an active antivirus. My Avast showed started and automatic in services. I then went into the admin account and re-ran the assessment. WHEN I LOOKED IN PERFORMANCE ISSUES IT SAID "NO PERFORMANCE ISSUES".

If I can run this:

To rebuild the list of counters in the registry:

Click Start, expand All Programs, and expand Accessories.
Right-click Command Prompt, and then click Run as administrator.
At the command prompt, type lodctr /r, and then press ENTER.

without having to do anything else, and not do any harm I'll do it. Otherwise I'll just ignore these errors.

I appreciate your helping me update those drivers and run the Mcafee uninstall tool. So far so good.

Sincerely, Libra

I don't foresee any problem running the lodctr /r command.

It seemed to work for perfmon issues in Windows 7 here.

You could create a System Restore Point beforehand if you decide to run the command.

Thanks auggy. I've been thinking about this and since you said I can ignore it, I think I will. I also noticed that among those Load Perf error they also include an "information" saying it was loaded, so maybe that's not so bad.

As far as the Windows Search errors go, the system and application errors both started on August 16. The only thing I did prior to that was install about 14 Windows updates (recommended and important) and I used the flash uninstaller tool to remove flash, I didn't delete the files, rebooted and installed a newer flash. I don't know if that could cause those errors. I usually look for system files when I'm using the search and it seems it's not designed for that, so maybe this service isn't that important.

I checked another Win 7 64 bit computer we have and it doesn't have any of these errors - although I found quite a bit of side-by-side errors going back to May 2010 - I have the feeling I never looked at that event viewer I may post a couple of them in another thread to see if any of them are important, although the computer is running fine.

Thanks for all of your help.

Sincerely, Libra
