Windows 7: BSOD Several Times per Day

09 May 2012   #1

Windows 7 Pro x64
 
 
BSOD Several Times per Day

The user started seeing occasional errors like this several months ago.

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.48
Locale ID: 1033

Additional information about the problem:
BCCode: 3b
BCP1: 00000000C0000005
BCP2: FFFFF80002AA3830
BCP3: FFFFF88005C59F30
BCP4: 0000000000000000
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

The frequency has increased to several times per day, often around 2AM when the system is not being used. Alas, this system is at a remote site and is currently hung. Since I use remote desktop additional tests must wait until it can be rebooted. Any help is certainly appreciated.

Running SFC /scannow initially resulted in a reboot from an error check. Following the steps in How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7 showed that NlsData0024.dll could not be repaired. I copied NlsData0024.dll from another Windows 7 x64 system without errors. However, running SFC after copying the file resulted in hanging the system without a reboot.

I created the attached files (Windows_NT6_BSOD_jcgriff2 folder and BigEasy System Health Report.html) prior to replacing NlsData0024.dll.

Windows 7 is
- x64
- the original installed OS on the system
- an OEM version
- System is 4 months old
- OS installation is 4 months old by Dell

System Manufacturer/Model Number Dell Optiplex 390
CPU: Intel Pentium G630 @ 2.70GHz
Memory: Corsair 8 GB 1333mhz PC3-10666 240-pin Dual Channel DDR
Integrated video Intel HD Graphics

Hard Drives: WDC WD2500AAKX-753CA1

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.




Memtest.
Quote:
*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

Quote:
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/Windows 7 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" 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.

Thanks for the advice. The box has no raid and no overclocking so that's not a concern. In several days when someone is on site I'll run Memtest86+ and Driver Verifier and post the results.
