So I just got an ASUS Rampage V Edition 10 motherboard and built my computer. This is like the 4th computer I have built, so I have done this a few times. I am having trouble getting the computer to get to the POST screen when I boot up for the first time.

So on the Asus motherboard there are 4 LEDs, called Q-LED to help diagnose any issues. The computer turns on just fine but it just stops when it gets to the the ASUS Q-Code A2 (which is for IDE Detect), and the Boot Device LED just stays lit orange.

So I thought it might be the drive device. I have an SSD and a regular SATA drive. I tried just connecting up only the SSD, then only the regular SATA drive, but no luck. Then I actually disconnected both new drives and connected an older sata drive that I knew worked, but still no luck. Still got to the A2 code and the orange Boot Device LED.

I did reflash the BIOS, but that did not change anything. I also cleared the CMOS and no luck there. I have an intel i7-6950K processor in there. That did not help. I pushed the switch bios button, but that did not seem to do anything either.

I also have 64GB ram in 4x16 configuration DDR4-3000. The motherboard has switches that let me turn off the memory slots. So originally I had all 4 memory slots on. Then I tried to go down to 2 slots, then only 1 memory slot active. Still getting the same issue with no POST screen, and stuck in code A2.

UPDATE: So again, I took all the memory out and put it back in again. I figured this problem is probably related to memory, because memory is always the problem right. Also, because I am not seeing any MEMTEST, come up. But still no luck.

I also tried to format the hard-drive and reconnect them to the computer. So I formatted them in Ext4, since I plan to use Ubuntu Linux anyway. That still did not help.

So I have kinda run out of ideas of things to try. I also pretty much disconnected all of the case connections, such as the audio to the case, the case USB ports, etc., to see if that might be messing anything up.

Anyone have any suggestions. I don't think the motherboard is broken since this is actually a replacement motherboard. I was having similar issues with my original Rampage V Edition 10 motherboard and RMA'ed it for this new unit of the same make and model. So the motherboard should be fine. Just can't seem to figure out what the deal is with getting to POST.

Any help would be appreciated.

One thing I noticed is that I don't hear any beeps when the motherboard turns on. There is supposed to be some startup beeps. Not sure why but I don't hear them. But I have no speakers connected to the PC yet.

Details on system config:

Asus Rampage V Edition 10 mb
Intel I7-6950K processor
4x16 Corsair Vengeance LED DDR4-3000
ASUS GeForce 1080 GPU
1 Western Digital SSD 500GB
1 Western Digital HD 4TB

 


So I am using a DVI cable from the geforce 1080 to my monitor. I see the bios splash screen come up after booting, but no memory test. Also, I push the DEL button while the computer is booting, but can never enter the bios utility. I have also tried holding down F2 which is the other key mentioned in the bios splash screen. No luck.
 


Okay, so I am making some progress here. The odd thing I noticed was that even after the bios splash screen passed and the screen went blank, the monitor power light was still showing Blue instead of Orange. So that means that the monitor is getting signal.

So I thought it might be an issue with the video card or monitor cable, etc. So I pulled out the monitor cable and as I was plugging it back into the back of the video card, I saw a moment where the computer had entered the bios utility. But then the video disappeared again.

So it seems like the computer is entering the bios utility, but the monitor is not showing it. Not sure why letting the cable be lose makes it work, but it still disappears after a second.

I will try a different video cable, but not sure if that will work. I wonder if it might have to do with Nvidia drivers and the geforce card? But usually that issue only shows up after the OS is installed. Arghhh.
 
Okay, looks like that was is. So I think that the monitor was going bad or something. I swapped the monitor with an old monitor I had and now the BIOS utility comes up just fine. Man, that totally threw me off for a few days. I tried everything, haha. Hopefully things will work now.
