Find program that takes over Win 10 computer while booting until a wifi connection is found

Greetings!

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.

Thanks,

Mark

first rule: use sysinternals autoruns to check the items that 'autorun' .. suggest you check the files with virustotal and exclude microsoft entries.

Also try starting in Safe Mode to see if the activity still happens in Safe Mode.   Win+R, enter MSCONFIG.EXE, Boot tab, start in Safe Mode.  

Also to David's point, run Autoruns in Safe Mode.

Finally, make a new, test Windows User Profile (Account). Log into the new Windows Account. Does the errant behavior continue?

Thanks for the comments and sorry about the delay in responding.  My water heater died a painful and wet death after I posted the question.  I should be back to troubleshooting in the  coming days.

After much difficulty trying to iron this out, I finally came to the conclusion that the issue was corrupted Win 10 files.  I tried a repair reload, but that didn't help.  I finally resorted to a full Win 10 reload.  Of course this was after a full backup of everything meaning full.  That seems to have worked.  I am now in the reloading software phase, Painful, but it is working.
