asus x99-a bios flash loop problem

[th2pun1sh3r]

hey everyone- I recently tried to do a bios update for my asus x-99a , after the flash it doesn't boot and instead goes into an infinite loop or powering on for a split second and powering back off... like its trying to turn on but it cant or something. I've tried multiple bios flashbacks using the usb stick and the button in the back.. My question is.. are there 2 bios chips on this motherboard (if so where? I only see one) and also what can I do besides replacing the chip.

update1: Ok so I tried reseating the ram, Cmos etc - I also tried pressing the MemOk button and reflashing- same thing. Also, I should note that I have a few more of these exact builds and the reason I initially wanted to do the bios update was because the motherboard in question had some issues with USB ports (mouse dc during a game etc). I thought it might be something with the specific motherboard so I tried doing the flash on ANOTHER x-99a same build previously working computer. Same result... computer tries to turn on..turns off.. loops

I am now convinced that whatever I did with the bios flashback has caused this but I am confused because I've done this process on all of my other motherboards without any problems.

Also, I have ordered a few x99a bios chips and the tool to safely remove them .. anyone have any other ideas or maybe someone in the MA area can come take a look? I really want to know whats going on this is starting to bother me lol


also made a quick youtube clip of what happens: https://www.youtube.com/watch?v=GXRJHUkIx-c

Looking at the Motherboard I only see one BIOS chip and looking at the manual there is no reference to switching BIOS so sorry man your board only has one.

Did you backup your BIOS to a Flash drive before you flashed the new BIOS on? If so try using the quick flash to restore the old one back. If that does not work try this:

Pressing the MemOK button.

This will rest all settings to default.

If these do not work, it appears that your BIOS Chip is replicable so you can either order a new one or contact ASUS for an RMA.

Hi,
"powering on for a split second and powering back off"
Try re-seating the CMOS battery, RAMs and all cable connections.
