Windows 7: BSOD when computer idle (not being used for x amount of time)

BSOD when computer idle (not being used for x amount of time)

Hello friendly people of the interwebs.
I recently did a complete reinstall of my system, using a new (bigger) SSD drive for my OS.
So except for the new SSD, no other hardware has changed. Same RAM, same Graphics card, etc...
Which has been working without any problems for the last few years.

But now on this new install, from the beginning I have been troubled with crashes so called caused by ntoskrnl.exe+a1d69 (always the same stacktrace). Having looking into this problem on and off for the last few weeks, I haven't been able to localize the exact cause to fix it. So i'm hoping someone here has some experience which can help in finding the problem.

Additional info:
So far the crash has only occured while I was away from the computer. And annoyingly I often lose data after a crash. As far as I can see I always lose the same couple of files on my desktop (but probably other files as well). And every time the crash occurs, to topleft of my screen shows the exact same (assumed) memory corruption (See attached picture). The crash even occures before I log on, if I let it sit there for a while!

Things i've tried so far:
  • Update motherboard BIOS
  • Update multiple harddrive related drivers
  • Update Samsung SSD driver
  • Update Samsung SSD firmware
  • Set 'Sleep after' to 'Never'
  • Set 'Hibernate after' to 'Never'
  • Set 'Turn off hard disk after' to 'Never'
  • Disable Hiberfil.sys (powercfg -h off)
    >>> all of these sleep disabling actions, because many signs pointed towards problems when going into sleep/hibernation/idle mode, and I remembered I also turned those off on my previous windows installation.
  • Turn off write caching on all drives
  • Ran Memtest86+ for a night (no errors)
  • Ran Chkdsk (no errors)
  • Ran Driver verifier (which pointed towards the nvlddmkm.sys driver potentially misbehaving)
  • Update Graphics card driver (Clean install)
I most likely missed other actions, but those are the ones I can remember.

Please feel free to contact me if I should provide more specific information or you have an idea where we might be able to find the problem.

Hi Pascal1-

The answer is to never leave your computer.

Honestly, the logs aren't very specific about what's causing a problem with IRQL requests.

I suggest going to Accessories and right clicking on Command Prompt. Select "run as administrator."

Type in sfc /scannow and let it run.

Does it find/fix any problems?

If so, reboot and run it again. Might want to do that up to 3 times if it's finding things.

Does that help?

Also, it looks like you're using VBOX. Do you have the latest version installed (v6, I think)?

Hi Wither

I have ran the system file checker and it didn't find any problems.
Any other ideas?

Just saw your second question.. Yes I have VirtualBox installed, but never had it running when the crash occured. Except for perhaps vbox service(s)? But I would assume they wouldn't be doing much when the vbox client isn't running? The version I have installed seems to be V5.2

I would update Vbox since it threw up this error in the event log from 11/22-

"The driver detected an internal driver error on \Device\VBoxNetLwf."

Okay, i'll go ahead and do that. I'll report back if that also was the cause of the crashes...

Unfortunately updating VBox to version 6 hasn't resolved the issue. But the driver error event log also still remains...
If I don't run the VBox client, are there vbox services (or drivers?) that are always running?
Also, any other ideas what might be the problem or do you suspect vbox is the actual culprit here?

I'd like to see the .dmp file, event log, etc. for the latest occurence of the BSOD.

However, go to Control Panel, System, Advanced System Settings. Click on the Advanced tab. Click on the Advanced tab in the next screen. How much Virtual Memory is shown?

The virtual memory page file size is set to 16325MB.
I have also attached the latest dump files again...

Hi axe0-

We had talked about that before and I think you said it was in the systeminfo.txt file. I don't see it there. Perhaps you would hold my hand and lead me to it.
