Updated BIOS driver-now ASUS will not boot.

I updated BIOS driver-now the ASUS Q550LF will not boot. When starting up, the ASUS logo comes up and I can enter BIOS. When letting it boot normally, the top left corner shows a little white bar which flashes twice. Then it goes to a black screen, still powered on, and does nothing.
Tried restoring defaults in BIOS That did not work.

Check and make sure that the AHCI mode is set correctly. It could be that the default settings in the BIOS are not correct for your configuration.

Since there is really no such thing as a BIOS driver, I assume you attempted to flash your BIOS? Evidently it did not work. Part of the flash process is to create a back up that will revert you to the previous state. Can you do that?
