Running Windows 7 Professional SP-1, I've had 4-5 instances of BSOD over the past month. Some of them are PFN_LIST_CORRUPT and some are IRQL_NOT_LESS_OR_EQUAL. I have WER-sysdata and minidump files associated with the crashes.
I've tested my hard disks, and one of them needed to be replaced, but the BSOD have continued. I ran memtest86, which did not report any problems. Driver verifier found a driver issue, but I've used that driver for years without incident. Updating to the most recent version of the driver didn't prevent BSOD from happening.
I'm trying to use Windows Debugging Tools to analyze the .dmp files associated with these events, but I have no experience with this. The console window says "Loading User Symbols", and nothing further appears there. The "Symbols" folder has some contents, but I don't know its significance. Guidance would be appreciated.
