Nothing in VEW that would explain the crash tho there was a slight uptick in the number of Hardware ECC Recovered so it may be more of the drive failing.  

Running the start-up version of CHKDSK took 50 minutes this morning, so I fear you're bang-on about the drive failing.  However, the PC still continues to run faster than it did before all this trouble began last week, so I'm grovellingly grateful to you for that.  Audio quality is improved too; I'm hearing things in the stereo mix which I'd never noticed before. However, video streaming is still stuttering somewhat and there seems to be a problem with audio and video being slightly out of sync, which I guess we'll have to blame on Seagate and chums.  I can't expect even someone as knowledgeable as yourself to be able to wave a magic wand and sort out poor quality issues.

 

I meant to ask, will MBAM and Avast come into conflict with one another, especially when they both attempt to block me from accessing what they consider to be a dubious website?

 

Many thanks.

I run Avast with MBAM and haven't had any problems.  They seem to get along OK.

 

For the  stuttering

You can try DPC Latency Checker:

 
 
The download is:
 
 
Just download, save and run it by right click and run as admin.  Do you see red in the graph?
 
However, when Process Explorer shows a low value for Interrupts it is usually not a DPC issue.
 
Interrupts 0.44 0 K 0 K n/a Hardware Interrupts and DPCs

 

 
What program are you using to watch your videos?  Start Process Explorer, watch a video and make a process explorer log at the point where it stutters.

Sorry for the delay in replying to your very helpful post.  It's been a tough week.

 

I downloaded and ran DPC Latency Checker and can report that none of the graph was in the red zone.  As for running Process Explorer to analyse the stuttering streaming problem, is the idea that I hit the stop button the moment a video stalls and then immediately run the scan?  I'm not sure the stop button will be of a mind to respond that swiftly when the stuttering strikes, but I can certainly give it a go.  Thanks for the suggestion.

 

Incidentally, Malwarebytes Anti-Exploit (Free) has mysteriously vanished from my PC.  What the dang [bleep].....?

 

Have a bearable weekend.

No need to stop anything.  Just have Process Explorer running at the same time, if the video/audio starts to stutter, switch to the Process Explorer window (Alt + Tab and then select the window) and File, Save As, Save.  Note the file name.   Open the file  on your desktop and copy and paste the text to a reply.

Not sure if I did this right.  Quite possibly I didn't.  But thanks for running an expert eyeball over it.

Something in Chrome is eating up the CPU.  Probably an Extension.  Click on the three bars in the upper right of Chrome and then Settings then Extensons.  Uncheck everything you do not need to play your video.  Restart Chrome and try it again.

Well, this is kinda mystifying.  The only enabled extensions I have in place are AdBlock, Google Docs, Google Sheets and Google Slides.

 

If I uncheck AdBlock and try watching streamed video, I'll presumably be plagued by on-screen animated adverts, constantly-changing static adverts etc. that'll place more of a demand on the CPU/memory than AdBlock itself does.  Maybe my CPU just needs to be taken to the vets' and put to sleep.

 

And as I mentioned earlier, Malwarebytes Anti-Exploit Free seems to have ceased functioning altogether, even though it's still nominally listed as an installed program.

 

Perhaps the moral of the story is simply that my PC urgently needs to rendezvous with a dumpster and be replaced by a shiny new can of worms.

Have you got a downloaded video you could watch?

 

Go into device manager and find your network adapters.  Right click on each and Disable.  Then play your video and make a process explorer log.

 

Also try changing out Adblock for Ublock origin

Then watch a video and make a process explorer log.
