Weekly 12B BSOD on Toshiba Z30T laptop

I wrote about this in my second post:

The thing about old drivers is that Toshiba has stated that they only guarantee that the laptop will work with the Windows 10 version available at the time of their own verification test (due to the evergreen updating nature of win10). Their test was done April 2016 so I have recently spent time reproducing an April 2016 install, which also means the laptop currently has Windows 10 v1511 update 2. I have tried to avoid driver updates (a few unrecognized drivers had to be fixed though).

I was on the latest Windows 10 when I first reported the problems but their stance is that my hardware is not guaranteed to work with any Windows 10 version coming after the one they verified in April 2016. Therefore I reproduced the 2016 install to show that the problem is there too. The machine is still under extended warranty so I have filed a report with Toshiba support about this hardware or incompatibility problem. Until they say otherwise I will keep the 2016 install. On the other hand they seem quite unhelpful and it sounds like they will not honour their commitment to any kind of compatibility with Windows 10.

Thank you both for analyzing the dumps. I was hoping to get an "easy answer" from there but I am starting to guess that this has to do with deep down stuff regarding BIOS/CPU/chipset and/or system drivers and that Toshiba's Windows 10 upgrade verification process has been flawed. As crashes appear so irregularly I believe it could have slipped through their Windows 10 verification.

I will probably wait for Toshiba's answer, and if nothing comes out of that or anything else, will try to disable Compressed Store.

As a side exercise: I would try to upgrade to 1809 and see if this resolves lack of stability - there's not reason to believe it would not work for you and taking into account 1511 age it's probably worth and prudent in doing so?

Alas! Is it offered automatically for your machine via Windows Update?


1809 works very stable for me (but so did 1709, I had issues with 1803 but perhaps one of the drivers / settings was reset during upgrade? Who knows!) and the advantage is that Microsoft is up to speed with patches for most of the Intel vulnerabilities with microcode updates with the latest versions (not sure what's the case with 1511 exactly).

Which would then also address what you've reported via PM.

@Ztruker
See post #3.
The OP deliberately installed windows 1511.

It seems it is possible to disable memory compression:

I'd really like to pinpoint the actual device or driver giving me the BSODs, but if that fails I might go for the above disable method.

Sorry for not getting back sooner but this issue was resolved by disabling Windows 10 memory compression. I suspect this new feature has had not much testing on older chipsets but are still getting the updated chipset drivers that enable it.
You disable it through a short Powershell command as seen in the answer here:
