I built a system around the GA X79-ud5 motherboard. G.Skill ram (16g), i73930 cpu, silverstone 1200 watt PS, Asus HD7970 directcuII video card, Seagate Barracuda 3tb, Samsung SSD, Lite-on Blu-ray, Noctua CPU Cooler.
I have not added speakers and wanted to get the thing up so I could set bios. It doesn't make a sound to indicate it is posting so I am not sure if the CPU is but it gets warm. The monitor searches then sleeps after looking at the ports (DVI) if I remove the cord it warns me so it SEES the card I think. The card is in the first PCI slot (tried the other one too) and it gets both a red and green light indicating it has power and both fans are running. I have pulled the ram and reseated it too. Pulled the GPU out countless times already. I have been reading that this motherboard has some issues. Is this one of them or should I return the GPU?
So I'm guessing you checked all the connections such as 8-pin CPU connector, main 24-pin ATX, and 2 of the 6+2 PCI connectors. Did you check to make sure you have your front panel connected correctly?
I sure did...to the point of obsession. I think it is either the MB or bad ram, I am sending back the GPU and getting something different that doesn't take up so much room. I also am sending the MB back to have Gigabyte look at it. I hope that does it. This is the first time I have had a problem with a system like this.
If you checked the Connections and it still wont post it's got to be something with the CPU or Ram .
Check the CPU for a Bad Pin if it is not a CPU Pin Try posting with one Stick at a time with the Ram .
I looked at the CPU and it appears that there are no bent pins...and I tried the Ram trick since I have 4 modules of 4 gig each...my gut tells me it's the MB for some reason though, but the obvious would be ram. I will post the cause when I find it though!
