Windows 7: BSOD 03b system service exception win32k.sys

I've had this crash twice in the past couple weeks. At least, the first one was 03b--not sure if it was win32k.sys, or a system service exception.



I keep my computer on 24x7. I have installed the latest updates from MS.

The first time I was playing Diablo 3. The screen went black and then came back several times over an hour or so. I believe I had quit out of the game entirely, and was maybe opening Chrome, when I got the crash.

The second time a video I was watching with VLC media player just finished, and full screen was going back to windowed mode.


I realize the screen going black most likely indicates a problem with the video card or driver, but it is possible that is a separate issue--I also use the HDMI output on my video card to watch movies and listen to music on my home theater system, and I often see the picture go out and come back there, as well. However, it is only recently that I've seen it happen on my main monitor.

I am overclocking almost all my components, but have had this overclock work stably for 2 years or so now. (Core i7 920 overclocked to 3.9 GHz, video cards (2 GTX 460 1GB cards) overclocked as well, but not terribly much.) The system is stable in all games that I've played, and in various stress tests. I've run memory tests at various points with no errors found, though not recently.

I did recently install beta drivers for my video card as recommended for playing guild was 2, as the latest release drivers aren't working properly with it.

I also installed AVG somewhat recently, to augment Microsoft Security Essentials.

Dumps from both crashes attached.

Welcome aboard, morik!

We need some more information. You post it again, following the http://www.sevenforums.com/crashes-d...tructions.html .

Sorry about that--the SF debug zip file is now attatched to the OP. It includes a couple crashes from June--I don't recall the details of them though. Haven't had any issues between then and now.

Thanks!

Bump?

Have you got any more crashes after 17th?

The last two dumps show bugchech 3B, with a cause ntkrnlmp.exe, which is not the actual cause. It causes for System service, Device driver, graphics driver, and memory.

In such a situation, it is better to enable Driver Verifier to monitor the drivers.

Driver Verifier - Enable and Disable

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

Let us know the results, with the subsequent crash dumps, if any.

I just got around to this today--I turned on driver verifier, rebooted, and left prior to fully booting up.
When I came back a couple hours later, I had a BSOD indicating a driver which was being verified failed verification.

Crash file in OP updated to include this crash as well.

Thanks!

It is MagicISO SCSI Host Controller driver it is crashing your system.

You need to get rid of that thing. Uninstall MagicISO, and report back.

And, dont forget to disable Driver Verifier for now. If it is needed if future, we will suggest it again.

Hmm that is unfortunate as I use MagicDisc upon occasion.

I happened to have 4 virtual drives active as I forgot to disable them after I was finished using them, but had no drives active at the time of the crashes.

I'll disable the drives and activate the verifier again to see if anything else shakes out.

After disabling the virtual drives, I ran driver verifier for 24 hours with no issues. Played games, watched videos, normal usage.

In this post, I suggested you to disable Driver Verifier.

Disable it now. Let us know how it is working in normal situation.
