Cant update 680i BIOS, help!!

hey people, i cannot update my bios on my evga  680i...  i will list things i have tried:

- Tried update center on Vista, but Vista hates it
-Tried update Center on a Hard drive with XP.   froze during the process.
-Tried 3 different floppy drives,  drive makes chugging sound and then stops and nothing happens during boot.
-Cleared CMOS and tried the above again. Didn't work.
-Tried updating Bios with a CD, and a USB drive,  didn;t work.

-Floppy disk and USB drives are both recognized on Windows.

Specs:
EVGA 680i Motherboard
e6600  2.4ghz
8800 gtx
G skill ddr2 800 ram
X-fi Platinum

I am all out of ideas people... If anyone could suggest anything i would appreciate it.  Is my Motherboard faulty?

Oh I forgot to say the USB flashing method is posted as a sticky in their motherboard forums. That forum is also where you will got tonnes more specific help with the EVGA 680i motherboard.matthewjackman

I built my rig last month and updated the BIOS using a floppy without problems. I did not have an OS on it at the time though, whether that makes any difference I am not sure. As above, I would certainly recommend going to their boards. That way you will get it sorted. Good luck!

hmm well i managed to update using a .iso file that someone made of the most recent bios update.. But still its weird that i couldn't use a floppy drive.

reckon its safe to overclock with this problem?
