Windows 10: Task bar briefly flashing when clicking in any game UI & crashes

When clicking on games Steam Games, Blizzard, etc. within their UI in order to move, change camera angle, etc. there is occasionally a brief white horizontal flash near the bottom of the screen. After taking a video and singling out a frame, it is the windows task bar. Games eventually crash. I have done much troubleshooting over the past week. I've ruled overlays, task bar settings, NVIDIA drivers, and many other things. I've reinstalled the games. I've reinstalled windows. I've reseated memory and even the CPU. I've switched game locations to different drives. I've run stress tests on memo

Start menu and taskbar options just flash briefly when clicked

Exactly the same problem on an Acer Travelmate 6293 running Windows 10 32 bits
1) When I click the power icon in the start menu, the sleep/hibernate/restart/shutdown option list pops up for a fraction of a second, then disappears.
2) The same thing happens when I click on the wireless network icon.The list of available networks flashes briefly, then disappears.
3) Same with the notification icon: the notifications window flashes briefly then closes.
The last built of Win 10 witch is functioning is the 14393.
Has anyone found a solution?

 

Start menu and taskbar options just flash briefly when clicked

Following a recent automatic Winows 10 update, my start menu and task bar items have been behaving strangely, preventing me from being able to perform several critical operations. For example:
1) When I click the power icon in the start menu, the sleep/hibernate/restart/shutdown option list pops up for a fraction of a second, then disappears.
2) The same thing happens when I click on the wireless network icon after clicking the hidden icons icon on the taskbar. The list of available networks flashes briefly, then disappears, preventing me from selecting new wireless networks.
3) I find that I must click on start menu tile items multiple times before they ultimately "take" and launch the associated application.

I have tried a number of different solutions I have found online, including rolling back recent updates, without success.

Does anyone know of a solution to this problem that will WORK?

Thanks.
