No, the computer wasn't in clean boot at the time of the update, just in normal running. It appears that the WiFi adapter (either the hardware or the outdated driver) simply doesn't work with...

Further to the above, the results are encouraging. Windows 10 Fall Creator's (version 1709) just loaded & launched with no problems at all, and virtually no error messages in the event viewer. At...

BTW, I came across an interesting thread on the Microsoft community. Turns out that a lot of people have this identical issue, with identical error codes, etc. One of the experienced folks there...

I don't have USB 3, just USB 2 I believe (the PC is 7 years old). The device manager only refers to USB, not USB 2 or 3.

I did try all the USB connections I have, and several 30 Gb USB's, but...

Well, the experiment seems to have worked, at least with the KB5057142 update is concerned. It downloaded normally, and the computer rebooted properly into normal Windows, without the black screen. ...

Okay. I went away from the computer for an hour or so, and it crashed again while I was away from it. Usual black screen, no messages, hard drive non-responsive, and on manual restart, got a...

I just ran HD Tune health & benchmark again. Here are the results:173798173799

I'll try running the memtest86 now. I don't know if it will be able to complete, as there's a Windows security...

Okay - I used the non-beta version again. Here's the report -173793 https://www.tenforums.com/images/attach/zip.gif

Apparently, that doesn't work on this computer. As previously, I just get a flash of a black pane with red text for an instant, and it's gone too fast to even see what was there. Is there another...

By the way - I went back into my Device Manager, to remove the PS/2 mouse & keyboard, and they're not there at all anymore. Weird. Of course, I had a black screen & non-responsive computer this...

Okay, I'll give it a shot.

I'll try doing the "clean boot" tomorrow (I've been up for 19 hours, & need some sleep!). It scares me, though - there are a LOT of steps to it, so I've printed off the instructions from the Windows...

I just checked, and my "metered" setting in WiFi is set to "off".

I'm working on that - it's a new, SSD, and it's small (247Gb). I'm moving everything possible to my Passport drives at the moment...

Okay, I have 47Gb free now on C:/

Here's the results of the...

Here are the results of the Partition Wizard scan -173735

I have no encryption software added, beyond what resides in Windows.

Here's a screenshot of the Disc Management results. The bottom two drives are Passport hard drives for data storage, and the "L" drive is for my system backups. There's one more, off the bottom of...

As per post #10, I don't have Ccleaner on my computer - it appears instructions 1-4 refer to results of Ccleaner.

I downloaded and ran "Whocrashed" - the results were as follows:

"Crash dumps...

Okay, I'll do that. Here's a .zip of the setuperr and setupact logs, if these are of any help -

I've re-read your previous responses, and see you've already said which of the Panther files you need to see. Until I'd started looking at the Panther files themselves, I hadn't grasped the meaning...

Uninstalled Malwarbytes completely this morning, and let the update happen (not that I have a choice). Same cycle, same crash to black screen. As soon as I booted up the machine, within 10 seconds...

By the way, you asked earlier what anti virus I have. I'm currently using Windows Defender and Malware Bytes Premium version. 3.1.1. Interestingly, I've just been looking at the Malwarbytes forum,...

Okay, thanks - that sounds do-able in the time frame I should have available. I tried "system restore", but it said it was unavailable due to my computer having been upgraded to Win10 more than a...

Okay - I guess the stuff I posted wasn't of use after all. I'll try the above in a couple of days, when I'm off work. I don't know if I'll be successful, as my PC is only usable for a short time...

Okay, I just ran the first log collector. and it created a .zip file on my desktop, as you suggested. Here's what it came up with:
