I recently learned to use verifier.exe and solved one problem with it. The system runs fine in normal operation now, but when verifier was active it did cause an additional blue screen when shutting down the computer. I do not know enough to be able to identify the cause of this error, and I don't know if it is a concern, given that I have no problems when verifier is not active. Do I need to try to fix it?
My dump file history and performance monitor reports are attached.
Notes on the dump history: I believe I have solved all problems except for the "Special Pool Detected Memory Corruption" errors of 4/12 and 4/24. The most recent "Driver Verifier IOManager Violation" is a whole different issue that applies to another computer--I installed the driver temporarily on this computer to see if it caused the same error that it caused on the other computer. I will address that issue after dealing with this one (unless someone wants to take a stab at it now).
My Windows 7 OS is the full retail version--I think (I assembled the system myself and installed Windows from an OEM disk bought with the components), x64, and the original OS on the system. The hardware and OS installation are all from August, 2011.
