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.
