I am seeing in this NG that there are similar problems to the one I'm
facing, but not exactly. So I'm posting. I cannot get to the standard
VGA screen for examining the BIOS settings, because there is no video
whatsoever. The vocal comes on and says there's an overclocking
problem, but this shouldn't prevent the video from operating, should
it? I know the MX4000 works in my older system, the MB is new. The A8V
book says something about 3.3V AGP cards are not supported, but I can't
find any tech specs on the MX4000, even in the supplied manual, so I
don't know if that's the problem, either. And I threw out my PCI video
collection months ago (I'll see if I can borrow one). Can it be as
simple as someone put it, "Some MBs and Video cards do not play well
together"?

Examine the edge connector of the MX4000. It will have two
slots cut in it, indicating it is a universal 1.5V/3.3V card.
Your motherboard will have a plastic key in the AGP slot,
marking the 1.5V position, and since the MX4000 has a matching
slot, that is how you managed to plug that card into the
motherboard.

I would start by unplugging the computer and clearing the CMOS.
See the procedure in the manual (section 2.6 CLRTC jumper).
Clearing the CMOS should return the computer to default settings.
(Or perhaps, even before trying that, use only one stick of
RAM - see below).

If the computer claims the BIOS is corrupted and prompts to
insert a floppy or CDROM with a BIOS file to flash, generally
that is the last thing you want to do. The reason the BIOS is
"corrupted", is there is something wrong with the computer,
and flashing the BIOS when the computer isn't healthy is
risky. The only time it makes sense to use this recovery
function, is if you just flashed the BIOS (say in Windows),
and so you know there was a possibility of the flash getting
screwed up. Then it might make sense to use the recovery option.
Most other times, it is some other underlying condition that is
causing that message, and not an actual BIOS problem.

Try to simplify your hardware as much as possible. For example,
use just one stick of memory (the manual says to use slot B1
for a single stick).

And finally, check your processor type on this page, and make
sure that if there is a paper sticker on your flash chip
indicating the flash revision number, that it is recent
enough for whatever processor you bought.

I have a gigabyte and I just got an asus mobo also. They both support only
the 1.5v video card. The gigabyte manual states that it won't boot with a
3.3v card but I don't see that warning in the asus manual. Oops on page 2-13
it says 3.3v cards are not suppported on this mobo.
