I am trying to find a nasty application on my Win 10 computer. It goes crazy during startup evidently looking for the internet. It stops everything and the display essentially resets about every 10-15 seconds. I thought initially it was the graphics card or a monitor switch I have, but, when I brought up the Task Manager, it was fine, with the rest of the screen constantly resetting underneath it. The app is in some kind off loop, with processes bouncing on and off so quickly that I could not successfully see who is causing the problem in Task Manager..
Once my wifi link has been established, the problem stops.
Is there any way to find the culprit once the situation has started, like switching to Safe Mode to find the last app started? Or, is there some application I have start first to isolate this activity.
Any help appreciated.
