after login the monitors are black

Hi Experts,

since yesterday we have some strange issues with WIN10 machines.
When the user logs in, the screen is black and you cannot click anything.
We have checked the monitors and cables, all ok.
Do you have any infos about this ?

When I check the services from this machine, I can see a lot of services are in starting modus.
See the screenshot.

And what was changed, the day before yesterday?
How long does it take for these services to finally start (press F5 to refresh the view)?

Do the monitors work in safe mode?

I asked our IT department, nothing was changed.

The problem, the services are always in STARTING mode and they will not finish.
Eprs_AdminSystem ArchitectAuthor Commented:
Yes, when we boot in SAFE mode, we can work on that workstation.

Nothing was changed - and you believe that... Ok, you might have a virus outbreak, then. Scan such a machine offline using this: https://support.microsoft.com/en-us/help/17466/windows-defender-offline-help-protect-my-pc

Would not hurt to update video drivers if you have user right.  In safe mode a minimal set of drivers are loaded including g a generic video driver.
Eprs_AdminSystem ArchitectAuthor Commented:
ok, we will test it.
Eprs_AdminSystem ArchitectAuthor Commented:
status now is:
if a computer has this issue, we connect remotely and start all the necessary services.
After the reboot it works again.

Any ideas ?
McKnifeCommented:
Did you do the virus check as advised? Then please share some feedback. If it came back clean, try a repair installation (aka in-place upgrade) .
Eprs_AdminSystem ArchitectAuthor Commented:
when the screen gets black and the user cannot do anything,
we connect remotely to the services.
many services in status : STARTING

We change these service to AUTOMATIC. After the reboot all fine again.

Do you know this issue ? Why this happens ? This is now our 10th machine....
McKnifeCommented:
Without your feedback on questions and suggestions by experts, it will not be possible to continue :-) Please revisit my previous comment and Jodi's comment as well.
Eprs_AdminSystem ArchitectAuthor Commented:
Virus check is ongoing
Eprs_AdminSystem ArchitectAuthor Commented:
And once more, it has nothing to do with video drivers, because after the setup of services, all works again.
But the question is, why it happens suddenly ?
Eprs_AdminSystem ArchitectAuthor Commented:
an inplace upgrade to the latest WIN10 version.
