windows 10 screnn blinking

After the installation after signing in it displays the Desktop. The screen blinks. The Desktop Icons are there one blink and not the next. Next to the mouse pointer there is ablue loading circle.

In Task Manager the CPU is clocking at 98% usage.

Host Processing For Setting Synchronization is jumping between 50 - 69 % of CPU usage

With Windows explorer clocking in at 15%...

So how do I fix it so that my laptop is usable again?

I have the exact same issue on my computer (which is not a laptop).

It happens even in Safe Mode, and even with my video drivers completely removed -- and also when completely reinstalled.

The login screen is not affected, nor is the Ctrl+Alt+Suppr screen -- Only the desktop is.



When I let the blinking going on and on, at some point after several minutes, even hours, it stops and the computer is usable as before.

I don't understand, and I am about to revert to Windows 8.1 to be able to use my computer normally :/

[Edit] It seems to be linked to Cortana / Start Menu -- Killing "Shell Infrastructure Host" will stop the blinking, but a critical error will popup, warning that Cortana / Start Menu cannot be loaded. -- The computer is still not usable then, and any Metro app / setting is inaccessible neither.

I just wanted to note that this may be SSD related.  I know it is odd but I just upgraded my Acer S3-391 from HDD to SSD, cloned the drive and upon boot up I noticed the screen was flickering and I could do nothing.  Putting back my HDD, everything was fine.  

Right now I think I need to reboot with the installation CD of Windows 10 and do a refresh install.

I had this problem and for me it turned out to be iCloud Photos.  Here is what worked for me.

I did control alt delete and started the task manager.  In the processes tab I found the iCloud Photos process and stopped it.  The screen stopped flashing and behaves normally.  Next I went into iCloud and unchecked the Photos component.

I have heard that another program with similar compatibility issues is Norton, there are probably others.

You can try killing processes one at a time until the flashing stops, that should tell you which is the culprit.

Even with the error reporting services closed as one mentioned my problem was still there.. 

Sometimes after starting browsing with Chrome so I was focused on Chrome being the problem as some mentioned. 

However when just now experiencing the problem again with blinking/flashing screen:

being able with ctrl-alt-del entering taskmanager - services I found the apple photo services (iCloud Photo) was actively processing... Shut that process down and voila.. screen appeared again without blinking. 

For some time the notification center showed on and off messages that iCloud photostream could not be synchronized.. This might be part of the problem.

It looks there are more people with different solutions closing down the processes that seem to be causing the problem.
