Question Request for Windows dump file analysis

[Savage One]

Hi guys, if someone could take a look at these dump files I'd be very grateful. They're from my little brother's machine who lives quite a ways from me, so I can't do hands on troubleshooting. He was having several BSODs a day, seemingly randomly. From the crash codes I've seen, it seems to be either driver or RAM related, but I guess that's what the dump files would tell us.

I'm going to attach two files, the first file was after a "random" crash, the most recent one. The second was after this, when I had him run driver verifier on windows and he got stuck in a BSOD loop on startup, which I've since gotten him out of. If you choose to help, I'll let you determine which, if not both, are more worthy of taking to time to analyze.

First dump file, last "random" one : https://www.dropbox.com/scl/fi/mk9y...ey=03j5zvweghfnv1ap4swhdl5df&st=fqdn4490&dl=0

Second dump file, when driver verifier was causing BSOD death loop: https://www.dropbox.com/scl/fi/k788...ey=v3b71v81qsp1z5sfrfagcwpjx&st=ddxpof5k&dl=0


Thanks

The Driver Verifier enabled dump wasn't triggered by Driver Verifier specifically, it's a regular SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. That just indicates that an exception in the kernel wasn't able to be handled by the error handing routines and so we had a BSOD.

The earlier dump is a DPC_WATCHDOG_VIOLATION, that indicates that a DPC (the back-end of device interrupt processing) ran for longer than allowed (the DPC code is in the device driver).

In both cases the device being accessed is a USB\VID_046D&PID_C232. You can see this in both dumps...

The USB device with VID_046D and PID_C232 is the Logitech Gaming Virtual Keyboard. I confess that I have no idea what that is, but from the name is sounds like a virtual device. It's certainly a Logitech construct. The three Logitech drivers that were loaded at dumnp time are a couple of years old...

    Information from resource tables:

I would suggest looking for updated Logitech drivers and find out what the 'gaming virtual keyboard' device actually is and whether your brother really needs it. It would be worth disabling/deleting it as a test in any case to see whether the BSODs stop.

You can deactivate Drive Verifier for now, if we need it activating again I'll give you some detailed instructions on which options to use.
