Thanks so much. I tried this, and managed to get into a bit of a snarl. It's probably a question of me not following the exact procedure described. It seems important to change the extension of the...

Thanks to those who tried to help me. Ultimately, I had to retire this computer. There was nothing physically wrong with the computer as far as I could determine. HP stopped supporting Windows 10...

This seems to be it. As far as I could tell, Heidoc is the only path forward. Maybe it's just me, but I could not find any reference anywhere else to a place to get the 1809 ISO fresh from...

I have an older laptop running Win 10 Home v 1803. The last version for which the manufacturer HP provided driver support was 1809. I tried 1903 on another identical model, and it crashed. It was...

I have reinstalled Bitdefender. The Advanced Threat Defense module is being triggered, and that shuts V2 down as soon as I hit Enter.

Hi, zbook,
Thanks for all your help.
I could not find the ISO for WIn 10 version 1809. I drilled down until I reached Microsoft human support (which surprised me, as I did not think it existed any...

I am operating under the theory that Win 10 version 1903 is not compatible with one or more HP drivers, which HP does not intend to support under 1903. They have essentially abandoned the model. We...

HP has not addressed the problem in any substantive way.
I recovered the laptop in question to stable condition by restoring an image backup with Windows version 1803. So far, it's stable. The...

Thanks.

I have uploaded the sfcdetails.txt file to Dropbox - memory dump 08-01-19 - Simplify your life

I will try the other suggestion after HP Support gets back to me, likely next Tuesday. ...

Okay. Just thinking out loud, but if the crashes have something to do with Windows Defender, maybe the answer would be to disable Windows Defender completely and go back to using BitDefender, at...

Okay. So, the only path forward is what - do a clean installation of Windows?

Thanks so much for all the thoughtful advice, philc43 and jdc1!

I changed the security settings on the \windows\system32\ copy of ish.sys and renamed it to ish.sys.bak. I also renamed about 10...

I will look for the V2 file and upload ASAP; that computer is currently running a HDD test.

I have no experience with comprehending what WinDBG displays, but ish.sys seemed to have been flagged...

Uninstalling BitDefender seems to have done the trick. The V2 log collector output is attached.

I'm using Bitdefender. It kept blocking the log collector when I ran it. Eventually, it found a .cab file in my temp files that it did not like, and quarantined it, describing the nature of the...

Okay, thanks. I will try that. Bitdefender has been acting a little weird on my other computer, but not, to outward appearances, on this one. I will see what they have to say about this error.

Changing the card reader driver nearly eliminated the BSODs, but since I last wrote there have been a couple more. I ran the log collector again. Please let me know if you see any more clues. ...

Thank you, maestro. There was no rollback option for the card reader driver in Device Manager, but updating it to an even more recent version (10.0.14393.21292) was an option. I'm trying that...

Thank you very much. I ran the test, more than 8 passes, 11 hours, 0 errors. Longest it has run without BSOD in weeks. Seems less likely to be a memory issue, correct?.

My uninformed suspicions...

Recently, my laptop has started generating BSODs after operating for a while. The time varies; it can be minutes or hours. I have run the Windows Memory Diagnostic, HP's hardware diagnostic tools,...
