Posted Today, 02:30 PM System Dell Optiplex 9020 MT (Refurbished) Windows 8.1 32 GB Ram Since a Windows Repair on 3/16/23 any time I log into my computer, the screen begins refreshing rapidly. I narrowed it down to a function in the "Thumbnail Handler Extraction Host" in the task manager. I've researched and found plenty of instances of others going through this year's ago, but their fixes didn't work for me usually it was because of Norton, which I never had. Quick Recent History Rundown This all mostly started after moving my primary HDD from one PC (HP Pavillion 500-023w) to the current PC listed above.
