I just tried upgrading my graphics card to the new GTX 750 Ti from EVGA. I have an ASUS P8P67 Deluxe mobo--latest 3602 UEFI firmware. When starting, the mobo hangs at the splash Press DEL key to Enter setup, but no keys work. It locks up tight on this screen (but display is coming through the new card!). Putting in the old card works, new card locks up. Anyone have any ideas how to remedy? I'd really like to use the new card! It doesn't look like ASUS is updating the firmware on this mobo anymore.
