Windows 7: Windows 7 BSOD casued by ntkrnlpa.exe and srv2.sys

Thanks so much, Justin.

Upon removing those two programs, do you suggest I run any tests to see if they were, indeed, the culprits? I guess I can always test whether I am able to start in safe mode, which currently, I am unable to...

Thanks once again for taking the time to help me!

We are right now troubleshooting. We are trying to narrow down the problem to be sure that we have the culprit. But yes try this in safe mode.

What happens when you try to boot into safe mode?

I uninstalled both SuperAntiSpyware and Norton Internet Security 2012. I tried to boot into safe mode, and again, the safe mode stalls at classpnp.sys.

I am able to boot into normal mode without problems.

Any ideas? Thx!

The computer is booting into safe mode again.

I think the problem was not so much that it was not going into safe mode. I think the computer was going into safe mode, but you just couldn't see it since there was no signal being sent to the monitor for some reason.

I opened up the computer and removed one of the graphics cards on the PCIe x1 slot (one came with the computer on the PCIe x16 slot, and and I added one to the PCIe x1 slot). I found that there was a loose connection on a cable to the DVD drive, but not sure if that had anything to do with it. When I started the computer without the second graphics card, and with only one monitor attached, the safe boot went normally. When I reseated the second graphics card and attached all the monitors, safe boot failed again - the screens would go blank again after loading classpnp.sys

Then, I decided to disconnect two monitors, and only kept one on, and guess what, the safe mode proceeded normally. So, there was obviously something going on when all monitors were attached, which caused the safe mode to stop sending a video signal. I was able to duplicate this multiple times. The problem seemed to be with the monitor with the VGA connector (the other two are DVI). I even changed the VGA cables, but that did not help. In both cases, the video signal would be lost. The strange thing is that booting into normal mode had no such issues!

I opened up the computer again, reseated the graphics card, tightened screws on the motherboard, etc., booted normally, uninstalled the graphics drivers and re-installed them. Tried to boot into safe mode, and everything worked as it should

So, at least the safe boot problem seems to be resolved!

BTW, since most of my dump files indicate that the crashes had the error code 0x0000007E caused by srv2.sys, I thought that this hotfix might be relevant, and have installed it. Any thoughts?

Operating system intermittently crashes with a "0x0000007E" Stop error message on a computer that is running Windows 7 or Windows Server 2008 R2

Okay, so everything is working now, and even safe mode with all the monitors plugged in?

Hi Justin,

Safe mode is working fine now, with all three monitors attached.

What do you think about the hotfix that I mentioned above? Do you think it's relevant to my crashes, as evidenced by the mini dump files?

Also, looking at the information that I uploaded, besides SAS and Norton, are there other issues that were identifiable from the reports? Outdated drivers, other conflicts, etc.?

Any advice is much appreciated! Thanks.

Nope - but the forum helpers need to know what's going on, otherwise you could end up getting conflicting advice, and then everybody gets confused.
