Windows 7: BSOD error C5

BSOD error C5

I've been experiencing an occasional and difficult to nail down BSOD. Using WDK, it looks like it's always a c5 error for a system file in order they were:
  • System
  • wmiprvse.exe
  • explorer.exe
  • wmiprvse.exe

I checked my drivers, they all seemed up to date. I was concerned it could be a memory problem so I ran a memtest, but I got nothing back. So I turned to driver verifier, but while it does enjoy freezing, it doesn't throw a BSOD, and I never get a memory dump. Kind of stumped on this one so I thought I'd reach out. Thanks in advance.

Hi MrInventor.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If it does not show any error, 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   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

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

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is
caused by drivers that have corrupted the system pool.  Run the driver
verifier against any new (or suspect) drivers, and if that doesn't turn up
the culprit, then use gflags to enable special pool.
Arg1: 0000000000000008, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff800031bfa9b, address which referenced memory
