Computer freeze.

[Clandestine]

I've just had another system freeze, but this one seemed a little different than normal. It was as a game of battlefield 3 ended and the freeze happened a lot quicker. I managed to force a BSOD but for some reason I got the error message "physical memory dump failed" then a string of numbers, but there were lots and gone too quickly for me to note. I know that dump files are being created as there was one generated from my last forced BSOD, do I need to delete that file from the windows directory before another can be created? I assumed it'd just overwrite. I have 28gb of disk space free on the SSD, so plenty of room and everything seems to be configured correctly to allow the dump, I'm assuming that's the case as it went fine the last time.
I've attached the ZIP from the SF diagnostics tool, I've no idea if that's of any help.

Too quick to note? I thought you had automatic restart unchecked? If so, the blue screen would've stayed, giving you ample time to record things down.

The "physical memory dump failed" makes me believe your SSD drive may be bad, or something is impeding on disk I/O that's preventing the crashdump to be generated. The possibility of the drive failing also helps my hypothesis that the freezing is caused by an interrupt storm, in that the drive is bombarding the system with disk I/O failures to the point where the system is frozen - that or the drive becomes unresponsive, causing disk I/O to pile up waiting on it.

I've just had another system freeze, this time the memory dump was successful. It's too large to upload here, do you know somewhere that I can put it that you can access it from?

 

[Vir Gnarus]

Mirrorcreator - Upload files to multiple hosts is usually a good start. It uploads to a number of sites so that if one of them doesn't work, another is bound too.

I've attached the diagnostics tool's file to this message and the dump file can be downloaded at http://www.doughtysonline.co.uk/connolly_test/Newsletter/MEMORY.DMP
Hopefully that can shed some light on the continued system freezes, and thanks again for your time.

The crashdump didn't end up being as obvious an answer as I thought it might be, but it does lay out some pretty considerable suspects.

First suspect is the MotionJoy driver. At the time of the crashdump, I see it showing up several IRPs that aren't getting completed and are stalling because the driver isn't handling the I/O properly. The result could end up with them sitting and the IRPs keep piling up unfinished. The driver is dated from Nov 10, 2011, so check for an update, and if there isn't, then uninstall it and see if things stabilize. Other notable mentions are your Saitek and Logitech drivers - make sure they're updated.

The other potential suspect is the AFD driver which is part of Windows TCP/IP stack, or rather whatever driver it's waiting on. I notice a good bit of IRPS reliant on this driver piling up already, and they're all pending waiting on some other driver to do its work so it can complete the I/O. I've yet to discover what driver it's waiting on, or rather what resource it may be waiting on, so I may look further into that. However, I have discovered that for all cases where the AFD was shown waiting on something, the process it's doing I/O for has been Chrome, so I know I'm on the right path here.

I did look at the raw thread stack for these, and the common elements I find in them are your graphics drivers and your network drivers (naturally). Try updating both, especially your network drivers since those are dated from 2010. You also wanna update your BIOS and your audio drivers too, since those can affect your onboard network device.

Again, I haven't gone enough to put the finger on anything specific, but this should help you get started. I'm not entirely sure I'll have the time to peruse it further, but I'll see what I can do about giving it another look.

Analysts:

Started by doing a full search of IRPs with !irpfind, then looked at patterns (such as the AFD ones) and narrowed the list down again using the proper flags, notably !irpfind 0 0 device fffffa80095ba8e0 for the device I found common with all the AFD IRPs. I found they were all pending, waiting on something else. Then I looked at the associated thread for some of the IRPs and most of them were for Chrome. My next step in the investigation will be to find if there's any resource contention using !locks, because I suspect they're waiting on a resource someone else is not giving up easily. Initial viewing of it doesn't look good, though it means I'm on the right track!
