Windows 10: Something flashing up on start up

How can I find out what's making this white box appear on my desktop on boot? It only appears for a split second, had to film it and pause the video when it came up. I don't see any text, just the white square.

Start-up Screen Flashing

When I wake my computer, I do not see the windows start screen. I see a flashing screen and a Iittle flashing square for the mouse. I have to either make my computer sleep and restart several times (up to 30 times) or restart my computer. I have Windows
10 on an Inspiron 13 7000 Series Dell laptop.

Moved from:
Windows /Windows 10 /Windows Hello, lock screen & sign-in

The following steps outline the steps to fix Windows failing to boot and you can boot to the advanced startup options.

There are a couple of way's you might be able to find what's causing this.

Look for programs that start during or after the boot process:

Open Task Manager -- Type " Task Manager " in Cortana an it should be the first on the list.

Click on the " Startup " Tab and disable something you think may be causing it





If you are running CCleaner.

Go to " Tools > Startup "





I have never seen this before, If you find the cause I would be interested in what it is.

 

As a starting point, perhaps use MS' TechNet/Sysinternals's AutoRuns?

The default Everything tab should show everything triggered for all profiles.

If you're unsure, you can use File > Save to save and post a .ARN file for others to check.

Hope this helps...

 

I couldn't see anything in any of those places that stood out but I have uninstalled malwaresbytes and it seems to have stopped doing it now. I guess that was it. Wasn't set to run on start up which was odd though.

 

Often these things are set to run on a shedule task check there as well

 

Possible it was Malwarebytes trying to quarantine an item on startup, and the item is no longer there. A quick flash of an empty Console window. If you put Malwarebytes back on, check to see if there is anything in the Quarantine section pending. Just a hunch, since you say it stopped when you uninstalled it. Of course if you put Malwarebytes back on, the Quarantine may be empty.

 

OneDrive updates often display a command prompt box on boot.
