LCD flashing when booting up

I’ve been noticing when I boot up and services are starting that right before the comodo icon appears in the toolbar my LCD screen will flash black for a quick second and back to the desktop. I was wondering if this is a Comodo issue. The only only services I have starting up are Avast, Nvidia and Diskeeper.

… follow up. I uninstalled comodo to see if there was a connection and there isn’t still getting flash after uninstall… Back to the drawing board.

How long have you noticed this? It could be a change of screen resolution. I know my monitor does that when it switches modes (e.g. playing a game) and when I first reach the blue welcome screen.
