Anything new? Having exact same Issue. Updating BIOS via Flashback did not help yet.
If anyone got a solution or the cause of the error, it would really be helpful.
I sent the board back to where i purchased it from, between when i returned
it and when they received it there was a new bios update which they assured
me they didnt install. but according to them everything just worked. i dont
know if the board was replaced or what the story was and they just didnt
tell me or what but it now works. i did note from the photo they sent they
were using a very thin video card and had the nic in the slot right
underneeth it something i could not do because my video card is 2.5 slots
wide. maybe that config cleared the issue. im personall of the opinion that
the board was secretly replaced.
