Windows 10: Random flash on screen every few seconds

I can see a random flash of a window or some widget on my screen every few seconds. I want to find out the application that is doing it. Any ideas how I can find out? Thanks

Screen flashes black for a second

Hi,

I appreciate the troubleshooting steps you have tried to resolve the issue.

Please answer these questions to assist you better.

• Have you installed all pending Windows updates?
• Do you get any error message?
• What is the make and model of your computer?

I suggest you to install all pending Windows updates and check as driver updates are also part of Windows updates.

Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

Also uninstall and reinstall Display drivers from manufacturer website and check. Refer the steps below.

• 
  Press “Windows + X” and select
  Device Manager.
  
• 
  Select Display Adapter and expand the driver icon.
  
• 
  Right click on the driver icon and click on
  Properties.
  
• 
  Go to Driver tab.
  
• 
  Select Uninstall and follow onscreen instructions.

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
