Hi!
I have been several times struggling with this same type of problem ...
but unfortunately not with A7V mobos', so, I do not have any exact advice
for this.
But, please check ASUS support pages for possible advice, as they are
claiming to have a "Crash free BIOS" on the page ->
http://uk.asus.com/products/mb/socketa/ ... erview.htm
Generally adviced, you should have, or copy to, the right(!) BIOS load file
on a diskette, and then at the boot-up, if you are lucky enough, the BIOS
code will automatically be loaded from the diskette file to the mobo's
BIOS NVRAM, I assume ...
If interesting, please read also of my latest "surprising" finding on BIOS'es
on the topic by name "BIOS in NVRAM" at the "In-depth high-tech BIOS
section" on these forum pages.
Happy flash trial moments ...
Regards,
Pete V.
