Hi, I have an Asus Maximus VII hero and it's not booting up. When I press the power button nothing happens. But all the motherboard lights are on.
And also bios flashback light keeps on blinking. Please help.

CPU: Intel Core i7-4790K 4.0GHz
Motherboard: ASUS Maximus VII HERO
RAM: Vengeance (2 x 8GB) Dual Channel DDR3
PSU: CORSAIR AX760
CPU Cooler: Corsair Hydro H100i

The bios flashback light should not be blinking which is an error indicator. Did you try to flash the mb using the bios flashback feature? What is the q-code led showing if anything? Have you tried resetting the bios? Is this a new build or did it work and then suddenly stop working?

I have been using the system for over an year now. Then one day it didn't boot. So i checked the bios flashback button and it was blinking. I managed to flash the latest bios update later that day and the system booted up. But the next day I faced the same problem again.

It sounds like the cmos battery is dead or something the way it's losing the bios. Have you tried replacing the cmos battery?

Are any led's flashing on the board while it's shut down or booting? What codes are showing while this is going on? A bad cmos battery wouldn't force you to reflash the board o boot. If its still under warranty I'd RMA it before the warranty runs out.
