BSOD playing World Of Tanks, Technical information ***STOP: 0x0000001E

Please help me. Thank you.

These crashes were caused by memory corruption (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!!!


1-Memtest.

*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 or 6 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.

2-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.

So, 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).

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 "Special Pool", "Force Pending I/O Requests" and "Low Resource Simulation" and click "Next"
- 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.

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 (an estimate on my part).

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.

If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:

Delete these registry keys to stop Driver Verifier from loading (works in XP, Vista, Win7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel

Bsod windows 7

Thank you so much for the invaluable advise. For the past whole week, I have done all Memtest86 tests with no errors found. Later, with the Driver verification process, BSOD happened within minutes and I have attached 2 mini dump files to you for further analysis.

Best regards,

Three problems are apparent...

First one related to bckd.sys Related to Blue Coat Systems, Inc.
Remove to test.

Second your Avast.
Avast can be a contributing cause of BSOD'S .
Please remove and replace with Microsoft Security Essentials AT LEAST TO TEST

http://files.avast.com/files/eng/aswclear5.exe

Microsoft Security Essentials - Free Antivirus for Windows

Third...Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

On completion you can use this Freeware:

MagicISO Virtual CD/DVD-ROM (MagicDisc) in its place

Using MagicISO to create ISO image files

 

[zigzag3143]

Its never a good idea to run more than one malware application. You are currently running Blue Coat and Avast. I would do as JMH suggests and remove both and replace with Microsoft Security Essentials.

If you absolutely must keep Blue Coat I would update it to the most recent version. Yours is from 2009.

Bsod windows 7

Thank you so much for the reply and suggestion, been waiting all day for this. I will do exactly as you have mentioned and see if BSOD will occur again.

Best regards.

 

[JMH]

Delighted to have helped.
Let us know how you go please!

Sure thing

Yahoooo! No more bsod!

JMH & zigzag3143,

you guys are Geniuses! After following your advise, the annoying BSOD is completely gone. However, I still wanted it to be sure, so for the past whole week I was using Furmark 1.9.2, Prime95, Memtest86+ diagnostic tools one after another to give my machine a tough time. I have also tried to play World of Tanks again, and there was no BSOD at all. Now my computer works like a champ, and I totally salute you two for great help.

By the way, how did you guys know how to pin point the 'culprits' just by looking into the mini dump? Care to share your technical know-how? Wish I could help others too.

Best regards,

AllenC
