If the asus program, did a backup of the old bios of the video card.
Simply choose the file and re flash.
It should work after you flash the old bios firmware back if it backed it up.
Most programs do for such an event.
Hope it works.
If not like I said RMA the card explaining, the cause of the card not functioning was due to the ASUS GPU Tweaker, crashing during the flash of the new bios firmware.
