Actually I could get into Safe Mode before and after uninstalling the devices. Although my
mobo is strange and I have to hit DELETE during POST to go into Safe Mode. But first it goes to BIOS and then
sometimes when I exit BIOS it will go into Safe Mode (other times it just loads Windows normally. There doesn't seem to be any F1/F5/F7/F10 button that tells Windows to go into Safe Mode, it's like whether or not it feels like doing it after I do the DELETE thing...
I think disconnecting the writers and reinstalling Intervideo will probably be the best thing - maybe I'll even reset all the BIOS settings to default.
