ASUS Sabertooth X79 motherboard issue - need help/advice

[KingerXI]

Hello [H], and thank you in advance for your advice.

I have an ASUS X79 Sabertooth with an i7 3930k, and I am having issues with it. I got it for free when I upgraded a local business' server. In the office, it stopped booting and didn't have video to the monitor, so I simply replaced it. It was a mission critical server, and there wasn't time to do a lot of diagnosis.

But now I have it at home,and I am a little more hopeful that it can be salvaged. This is what it is doing:

It will POST (beep), power on my monitor (so there is some kind of signal going to it), but it will not go into BIOS (no words at all on the screen). The monitor is simply powered on and stays black.

I have cleared the CMOS several times, I am using a known good Seasonic PSU, I have used several sticks of ram that are known to be good, I have plugged the keyboard and mouse into different USB slots, and I have installed two different video cards (known good) into all three PCIe slots. I get the same results every time.

It appears to POST (with the beep), the monitor immediately comes to life, but no BIOS screen. Tapping DEL does nothing.

Do you think it may be a corrupted BIOS? I think that is a best case scenario, as the chip is only $14 on eBay.

Let me know your thoughts.

I bet it's the processor, you can go ahead and ship it to me and I will gladly test it in my system for you. If it proves to be faulty, I can even dispose of it for ya

In all seriousness, it seems that that board has a BIOS Flashback that, through a quick glance, should allow you to flash/reflash the BIOS with nothing more than a USB drive and power to the board. It's worth checking out, at least.
