Windows 7: Random BSOD Memory Management - 0x1A

Random BSOD Memory Management - 0x1A

So we hashed out an issue with my G19 keyboard causing 0xC1 and other BSOD's (0xC1 SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION on new build) last week and the week before... Thank you Golden! I now have a new issue...

I am now receiving seemingly random 0x1A Memory Management BSOD's starting on 1/11/2015 (Everything before 1/11 is most likely linked to the keyboard). One started seemed to start on video playback on a website, the others seemed random.

Troubleshooting I have run both Win 7 Memory Diagnostic (Full Check) and Memtestx86+ (12 Hours and 10 Passes) and both came back clean.

Any ideas?

1. Log in as administrator, open Windows Explorer and go to C:\Windows\Minidump
2. Delete all .dmp files in that folder
3. Run Driver Verifier as follows:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Driver Verifier - Enable and Disable

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal, re-run the DM Log Collector, and upload the new ZIP file here.

I recommend creating a system restore point before turning on driver verifier:
System Restore Point - Create

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:
Safe Mode

Thank you for the response and your assistance once again.

I enabled Driver Verifier and restarted. Immediately after login (No password set for testing) and desktop loading, I received the attached BSOD's with following BSOD.

The DMA Subsystem has detected an illegal DMA Operation

STOP: 0x000000E6

I rebooted and received the same BSOD and stop code.

Im just guessing here since the only ISCSI device is the RocketRaid Controller......try updating the driver. Use system as normal - do not run Driver Verifier again - and lets see if we get another BSOD.

I have updated the RR 2640X drivers. Strange thing as I had downloaded them during initial setup and was pretty sure I installed them. I may have removed the new drivers after my array dropped offline and I uninstalled and rebooted.

I restarted and was about to disable Verifier (I missed the Safe boot option) when I received a BSOD linked to Asus drivers which I then proceeded to uninstall and restart. I will close this out and start a new thread if I receive a different BSOD.

Thanks again Golden!
