Well, I don't have many experience with uefi, but I'm sure there is option to reset settings to default values, you could try that...
I recommend you create new thread, maybe in hardware section of forum. Then more people could help you.
Hi people, I'm in the need of the 8MB bios file of a Asus G75VW-BBK5 notebook (not the one that can be downloaded from the Asus site). Does anyone around here have it and can share it ? I would really appreciate it, I have my system bricked.
