Asus Maximus VI Hero Motherboard Won't Boot into BIOS; Stuck with 00 LED Code

I built a new rig three months ago and had everything up and running nicely. Just a couple weeks ago it shut down randomly, then wouldn't boot into bios. Instead it would turn on but get stuck with a 00 led code and black screen. I've searched an entire week for a solution but couldn't find anything that helped. I've tried checking the board for defects, replaced the cmos battery, used asus' bios usb flashback feature, switched power supplies, tested with a friends cpu, ect., but nothing seems to work. I even contacted asus for a solution or a rma request but they still haven't replied. I've basically build a new rig around this motherboard and still have the same symptoms as before so it has to be a faulty motherboard. I'm very upset that a $200+ board would be acting up like this without any solution and poor technical support from the company and makes me question if they have just lost a customer. Please If anyone had this happen to them and found a fix, please tell me.

Asus is a pretty good company, give them another call and ask for a status on your problem.

do you have any peripherals attached to your pc, like usb or any thing else? Remove that and then try booting.
If nothing like that, check your RAM sticks. Boot with single stick and check the results. Still doesn't work? Try to dissemble everything and clean with compressed air, every slot. Check for bent pins of cpu socket. Then assemble every component carefully outside the case and see if works?

I've tried a new single ram module on each slot but still no success. I also tried booting without any peripherals, basically just the CPU, RAM, Mobo, GPU, and PSU outside of it's case while troubleshooting. I haven't tried actually cleaning it or blowing dust out, tho there's not a whole lot of dust. And yes i've checked the board thoroughly for defects but it looks fine.

boot without any ram inserted into your motherboard. Do you hear any beep sequence?

I don't currently own a motherboard speaker but no, when i try to boot without any ram modules installed, it still says 00 without any beep. Also, none of the side leds are on such at the ram or cpu led indicator. Only the main led screen at the top.

Try Updating your motherboard bios again, you need to use a Fat32 formatted flash drive in the correct USB port and the file needs to be renamed properly for the flash to work. And if you can afford motherboard speaker it would be beneficial though.

EDIT: Make sure, in bios you have selected AHCI mode for your storage, NOT IDE. Also if you have overclocked anything like RAM, cpu, gpu, try to put it on default.

Tried flashing bios once more after carefully reading the manual 4 times on how to properly do so and still nothing. I didn't overclock on the rig when it was up and running; Everything was stock speeds. I got the rma acceptance email yesterday and am going to ship it back today. I appreciate your help but it seems like nothing has worked. Might just be a bio glitch or somehow got bricked. I'll just wait for the replacement and work from there.

sometimes there are issues with bios chip, and difficult to find if it happens after some time period with working board. Anyway glad you got RMA acceptance, good luck for your new board :)

I bought Gene VI and Maximus Hero , with 2x4470k cpu's. Each system turned into "code 00". First system worked 3 days, i tought it was bad luck so bought the other one :)  it booted fine , but after 2 hours of usage , it gives "code 00". No overcklocking at all.

I tried remove all , clear cmos , update bios with flash (works nicely without os)
Gonna hand the heap of hardware back to the shop tomorrow. I wont buy anymore of these cards from Asus.
