When you see this A3 QCODE, does your system halt? Do you get any video on your monitor? Do any of the QLEDs beside the 24 pin power remain lit?

Sorry to resurrect this post, but I am having this same issue with my board. The computer was working this morning before I left for school, but now it wont even post when I power it up.

I am getting an A3 code and the VGA QLED will remain lit. I have tried moving both of my 980's around to different slots and different combinations (including single card vs sli) and both errors remain. I've checked SATA cable connections, tightness of the CPU block for the CL water cooler I'm using, power connections all around the board, and everything seems just fine. Power is being supplied to everything that I plug in (980's are Windforces and they light up and fans come on just fine), but my monitor fails to display anything beyond a black screen. After about 15 seconds, the monitor will go into standby mode as it if isn't receiving a signal. This is what lead me to think something was wrong with either my graphics cards or the PCI lanes on the board.

I would suspect the PCI express lanes are crapping out, but I ran into this same problem a couple months ago while running my 980's in sli and was able to solve it by removing one of the cards and running just a single GPU. Switching to one card seemed to solve the problem just fine; VGA QLED went out and I was able to get to Windows log-in screen. Plus, I've only had the board a year and a half, so I would really hope the lanes are still in decent shape. Except now the same problem is back, and I can't seem to fix it by switching around the cards.


Thanks in advance for any help anyone can give me.
