First off, do you have another video card or an integrated GPU that you can switch over to?

You'll need another GPU so you can see to flash the proper BIOS back onto your 780.

Take the GTX 780 out of the PC and then try to boot it. It should automatically recognize that the GPU has been removed and will switch over to the iGPU. From there you can set the iGPU as the default in the BIOS. You'll need to use "nvflash" to reflash the card with the proper BIOS.
