From "Tried all fixes above including upgrading PRE to 8.1", I am assuming that your are working with Premiere Elements 8.0/8.0.1 on Windows 8.1 64 bit.
Let us go through the typical Premiere Elements 8 drill...
a. 8.0.1 Update installed, apparently yes
b. Automatic Background Rendering and AutoAnalyzer features turned Off.
Automatic Background Rendering...See Premiere Elements 8.0/8.0.1 workspace Edit Menu/Preferences/General
AutoAnalyzer - See Elements Organizer workspace Edit Menu/Preferences/AutoAnalzyer Options.
c. Is your video card/graphic card up to date according to the web site of the manufacturer of the card. I see two cards mentioned. Often Premiere Elements does not work with a two card situation. Have you tried disabling the Intel HD4600? But before even thinking about that, the important question becomes "Is this a it never worked before problem or one where it worked before but not now?"
Let us start here and then plan troubleshooting strategy according to your reply.
Thank you.
