Windows 7: Intermittent win32k.sys BSOD Error

Intermittent win32k.sys BSOD Error

Hi all,

Today I randomly started getting BSOD's referencing a page_fault_in_nonpaged_area with a file called win32k.sys. I haven't very recently installed any new hardware, although I got a wacom tablet about a month ago. Haven't noticed any trouble with it.

What did change today: I attempted to switch from AVG anti-virus to Ad-Aware, but I do not believe AVG properly uninstalled. (I went about uninstalling it through the control panel as I normally would, but no matter what it always still shows up there. Ad-Aware won't install now, either... it just keeps giving me an error about being unable to connect to the update server.) I also started using soluto to boost my boot time, so perhaps something got delayed or removed from startup processes that shouldn't have. Soluto sent me a little notification stating the error was likely caused by "nt driver" but I'm not sure what that means. (I'm sure that's all in the attached zip file.)

The BSOD is appearing intermittently and doesn't appear to have a common trigger each time. Usually about 10 to 15 minutes after using the computer it pops up and restarts the system. It happens every time I try to open photoshop, however, so perhaps that's related. Please let me know if I can provide more information. Thanks in advance to any and all who can offer advice.

- Spencer

I was able to get a picture of the blue screen I was seeing. It keeps happening, and it appears to be happening even more frequently today. I ran cccleaner to see if that would help, but it didn't do any good. I also tried using the computer in safe mode, both with and without networking, and I continued to get BSOD's, although the safe mode one was a different error.

I'm very stumped as to what is going on, and I'm also getting increasingly worried as the problem seems to be getting worse. The first image is my main BSOD, the second is the one I got in safe mode which is slightly different (system_service_exception.) Everything appears to be going back to this win32k.sys file, but I'm not even sure what purpose it serves.

Ok, I followed instructions from this thread, but it has still not solved my problem. This BSOD is happening every time, without fail, although what and when it's triggered appears to be random. Below are my ChkDsk results. I also ran sfc /scannow 3 times and it returned no errors each time. Examining the .dmp files in my original post, the only common driver in all of the files is ntoskrnl.exe, which I believe is referencing that nt driver again. I'm not sure what this is or how to fix it. I guess I will continue to try and figure out what I can. Any help would be extremely appreciated.

Here is another set of dump files collected using the diagnostic tool. I would upload them after every BSOD, but there would easily be 20 different versions by this point. The errors still appear to be affected by this ntoskrnl.exe file. If there any additional info needed please let me know. I will run whatever diagnostic people need to see.
