Random BSODs, BAD_SPOOL_CALLER (c2)

Greetings, everyone. Unfortunately, I've been having random BSODs for the last few months with more or less the same error. I haven't been able to figure out what's causing it, because it's very sporadic. Sometimes I'd go weeks without seeing one, then all of a sudden, BAM! Then I won't see it again for weeks. It keeps happening, though, but is so unpredictable. I almost always have Firefox and Microsoft Word open, as I mostly do writing projects on my computer.

I've scanned for viruses and spyware several times with different programs, but never found anything. I also routinely check for hard drive errors with chkdsk, which always turns out fine. Not sure what else to do. If anyone can give me some advise, I'd greatly appreciate it. I attached the .dmp file to this post.

There's something wrong with your crash dump.

What settings have you chosen regarding crash dump writing?

Go to Start
Right click My Computer
Then Properties > Advanced system settings.
Then click Settings under the Under Startup and Recovery section which is on the Advanced tab.
Finally under system failure choose Small Memory Dump.

Then follow these instructions on how to enable Driver Verifier.

Enable driver verifier but only enable the options: Standard settings and IRP logging step 3.
Don't enable Force Pending I/O Requests

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.

   Information

We use Driver Verifier as it puts a stress on the drivers, and so it makes the unstable drivers crash. This should flag the driver responsible in the dump file.
It

Driver Verifier will make the system laggy, this is normal so don't worry.

Before enabling DV, make sure that you have earlier System restore points made in your computer.

If there are no points, make a System Restore Point Manually

I have a hunch that there is an audio driver causing issues but I'm not too sure at this point.

Post back the results.

I've attached an image with the settings of my crash dump. It seems normal to me, but check it out and tell me if anything's amiss. As for the Driver Verifier, I'll give that a shot.
