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.
