I have been running a program at boot that by passes the lock screen so

I will turn that off , Turn off windows password log on and just boot right

to desktop and see if that works with no black screen.

Edit : ... We'll I did the above and of course it boots faster not stopping to sign in and been

OK for a couple days now , but this morning got one more black screen at boot .

Has to be a Windows thing as my other goodies don't load till after I'm on the desktop.

None of the youtube fixes have worked , so I'll just live with it I guess not going to do a

format and reinstall ............. I've gotten used to it now so it now seems normal for me .  

Edit 2 

I did replace a stick of ram a few weeks ago , so I replaced that with the original 

stick of ram today it reads fine , maybe that hardware change caused a black screen >

We'll see ...

It is a Windows 10 issue for sure.  The fact that there are several posts about fixing it on youtube says it's more a widespread issue than just those people here experiencing it. 

I don't know if this is related or not, but when I had issues earlier with my license key, a MS representative told me that thousands of Win 10 keys were retired due to installation and activation issues.  How a set of letters and numbers would affect a Windows installation beats me, but that's what he told me.  How it's relevant to this issue I don't know, but MS needs to investigate and fix it.

Just got the October update. Two of 'em. KB 4458469 cumulative update and KB 4100347 regular update. The regular one installed easily but the cumulative one failed twice. After rebooting for the regular update I tried a third time and that one worked. All told four hours of not doing much of anything. No black screen though. Knock wood.

And how many times has that 'contact us' button been used and still no solutions?

let's put it this way. tdr issue apparently existed since win 7 or 8 and still not necessarily fixed in win 10. not really related to their issue, but still. probably some obscure thing that's difficult to find because of all the backward compatibility stuff that they haven't gutted out after all these decades.

just upped to 1809. so far so good... but i haven't actually done a thing with it

Me too the last couple days both

black screen booting and while working on project black screen .

No I haven't done the 1809 update yet , had one guy said Deskscapes didn't work after he updated.

So I want to get a external hard drive I have working right and do a complete mirror 

back up before I do the update .

Al would you report back after you update how it works for you , any problems that

you find if any ...Thanks

OK, I think I get first Prize , as I just had my TV screen go black 

had to turn off and back on the cable box to get the picture back .

I guess the black screen is some kind of Virus now spreading though

my electrical systems.         

@ALMONTY - I reported your 1809 issues/findings to support

funny thing. i put machine to sleep last night after using 1809 all day. wake it up this morning and monitor was still asleep forced shutdown with power button and boot went fine. though kinda oddly, it didn't scream problem at POST (normally it'll say problem at last boot and change the memory clock to not xmp and i'll have to go into bios and change it back)

forgot to say, i didn't reboot or shutdown all day after upping to 1809 (aside from sending it to sleep)

and the last incident was a few months back..

--

set it to sleep for an hour or 2 earlier.. woke it up ok. let's see what happens tonight

--

updated gfx driver. rebooted. slept. woke ok.

5 black at start up last night 

Thanks noted , I'll try that fix next time it happens 

I have played with my Ram sticks lately still got the black screen

my PC is New so ran a check and all hardware checks out Good,

But I did uninstall my Video driver ( Radeon ) yesterday and then 

reinstalled again to the latest version and no black screen yet 

after about 6 boots .

So we'll see how that goes .
