Windows 7: Memory Management BSOD

29 May 2012   #1

Windows 7 Ultimate x64
Memory Management BSOD

I am getting this error every time I try to render a video using Sony Vegas. I have rendered many videos and have never had any problems. First I tought it was Avast, so I uninstalled it. But it still crashes.

I have ran Disk Check and Memtest and no problems where found.

I have attached my minidumps. Thanks.

Win 7 Ultimate 64-bit. SP1.

I note you said you ran Memtest but please run it again...

These crashes were caused by memory corruption/exception (Cx05) probably a driver.
Please run these two tests to verify your memory and find which driver is causing the problem.

* If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

* If you have a Raid update its Driver.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5-7 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+

Driver Verifier

Using Driver Verifier is an iffy proposition.
Most times it'll crash and it'll tell you what the driver is.
But sometimes it'll crash and won't tell you the driver.
Other times it'll crash before you can log in to Windows.
If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise.
Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation"IRP Logging and Force Pending I/O Requests. and click "Next"
NOTE: You can use Low Resource Simulation if you'd like.
From my limited experimentation it makes the BSOD's come faster.
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

If you are using win 8 add these

- Concurrency Stress Test
- DDI compliance checking

Reboot the system and wait for it to crash to the Blue Screen.
Continue to use your system normally, and if you know what causes the crash, do that repeatedly.
The objective here is to get the system to crash because Driver Verifier is stressing the drivers out.
If it doesn't crash for you, then let it run for at least 36 hours of continuous operation.

Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Thanks to JCGriff2 & Usasma.

Windows 7 Ultimate x64

I did some more testing using Driver Verifier.

Since HidClass.sys is a usb driver from Microsoft, I decided to try to isolate the problem.

Here is a table of what I tested and the output:

All Drivers - Crash
All Drivers except Logitech Drivers - No crash
Logitech Only Drivers - Crash

Since only logitech drivers where causing the issue, I tested them one by one to try to find the culprit. Here is the result:

lgbusenum.sys - No crash
lgvirhid.sys - No Crash
wmbenum.sys - Crash
wmfilter.sys - No Crash
wmvirhid.sys - Crash
wmxlcore.sys - No Crash

All of the crashes listed above showd HidClass.sys in the BSOD. Going to try to remove these drivers and render the video again.

I removed them and still get BSOD when rendering a video.

It says:

Stop 0x00000050

Going to try to downgrade my graphics drivers.

Windows 7 Ultimate x64

Bump, can someone please help me please? I have reformatted and tried everything and I still get random BSOD when playing games or trying to render videos. Error messages are IRQ, Page Fault in Non Page Area, and Memory Management. At this point I wish my ram was the culprit, since it is cheap to replace but I have been running memtest for 2 hours and it hasen't found problems.

Is it possible something else is broken? I will leave the test running for a little more maybe it will find something.

Windows 7 Home Premium 64 Bit

It would be easier to help if we knew more about your system. Right now, we know you have a computer with Windows 7 Ultimate x64 installed. There are literally millions of different hardware/software combinations for such a system.

Please follow the to provide more information by providing your full crash reports, system logs, and system information.

Also, fill out your system specs by following System Info - See Your System Specs. Fill out your system specs in your profile, not in a post in this thread.

Is your system pre-manufactured or custom built? Is it under warranty?
