BSOD PFN List Corrupt

Greetings and thanks in advance for your help. Our system is experiencing frequent BSOD issues. Attached are the requested files per the posting instructions.

Our system is running Win7 64 Home Premium. We have an EVGA 750i SLI mobo and an EVGA GTX560 video card. Memory is 4GB (2 sticks, 2GB ea) of Kingston HyperX. We have a WD hard drive. The CPU is a Core2Quad Q6600 at 2.4 GHz.

In addition to the BSOD issues we also have constant video card crashes when playing Battlefield3.

Win 8 Release candidate 8400

Nothing is attached try this method.
We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.
Please attach the DMP files to your next post not to post one.

If you are overclocking STOP

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:
* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.
To ensure minidumps are enabled:
* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

Win 7 Ultimate 64-bit. SP1.

1.Kaspersky is a frequent cause of BSOD's.
Please remove and replace it with Microsoft Security Essentials AT LEAST TO TEST.

Microsoft Security Essentials - Free Antivirus for Windows

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.

Thanks. We removed Kaspersky (ZoneAlarm), replaced it with Microsoft Security Essentials, and ran memtest overnight. Memtest completed 10 passes without any failures. We'll move on to the driver verifier next.

Edit: We had a new BSOD event yesterday referencing 'Bad Pool Caller'.

Submit any further DMP's.

NB. It is much easier to find patterns, etc, when there is more than one crash.

We prefer you wait until you have at least two so that if one is corrupt the other probably wont be.

Please upload them when you have collected 2 or more.

Thanks, yes, we did install the security essentials right after removing Kaspersky.

I've attached the errors file you requested and will work on getting Malwarebytes installed.

Unfortunately our 'fun and free' weekend is ending now so we may not respond again until tomorrow evening but thanks very much for your help.
