Windows 10 Screen Blacks out and Flickers for Multiple Users
We are having an issue with a group of brand new Windows 10 PC's that are located in an area where multiple users log into them throughout the day. Users are reporting that they can be running an app and the screen will go blank and the monitor power cycle itself, like sleep mode kicked in and then it came back on. Some say it happens so frequently that you can't hardly use the machine.
This problems happens more often at night than during the day, as the PC's are located in a 24/7 office.
We've made sure to install the latest video drivers, updated the BIOS, checked all the cabling, checked the power settings so nothing sleeps or hibernates, and even swapped out two of the PC's with two brand new machines - all with the same results.
Yesterday I noticed one of the PC's had 7 different users logged in. Apparently, nobody knows how or bothers to log out and so by the end of the day there could be a dozen active logins on some of the busier computers. I think THIS might be the issue. The users are blaming Windows 10. Event Viewer doesn't show any one particular app crashing but i just can't seem to find what's making the monitor cut off and back on.

Agreed, it should be easy to test. Use a script to log off disconnected sessions:

We're leaning toward it being a memory leak in an app. So hard to pin down where it comes from. Any other suggestions?
I don't see memory leaks in well-behaved applications (all my applications fit in this category). Do you have legacy applications that might cause this?

I ended up finding a tech support bulletin from HP regarding some specific driver updates. We installed that Friday afternoon and will continue to monitor. If that works, I will share the link.

We resolved the issue by fully updating the BIOS. As it turns out, there are 4 different BIOS updates for this PC, and they must be installed individually, in order. If you try to jump to the last one, it will fail. The whole process takes about 30 minutes, which is really annoying. I think HP screwed something up majorly with this line of desktops, but at least the flicker thing went away.
Thanks for the update and I was happy to help.
