Hello, for the last 6 weeks I cannot seem to get a motherboard to boot to the windows desktop with video card in 1st PCIe slot, the one next to CPU. I have 2 Corsair 1200 watt PSU's less than a month old, 1 Coolmaster 750 watt, 2 CPU's i7 950 and i7 960, 12 gigs of G Skill 1600 ram, ran memtest for 6+ hours, no errors, several passes. I have tried various video cards that are new and work in other systems. The boards for the most part will boot to the desktop in slots 2 and 3 but hang on the splash screen if plugged into the 1st slot. My new Big Bang II X79 powered right up with same power supply and video card along with the same new hard drive with fresh install of Win 7 pro OEM yesterday. The boards have all been tested outside the case with 1 stick of ram, one video card and CPU cooler. The 8 pin cpu power supply cable plugged into the MB and 2, 6 pin cables plugged into video card. All my systems run off the same 2 APC 1500 watt battery back ups, which I can see the voltage being provided to the systems. This has happened on 2 brand new and one refurbished MB that I have bought in the last 4 weeks. If anyone can offer any suggestions, I would greatly appreciate the help. As I had stated earlier, I had my new X79 sitting by the way side trying to get my X58 working again, but decided to get it started and I had no troubles with it. I realize that it is a differant cpu and ram, but same psu and video card.
When working, below is my system configuration. At present, I am using one of the motherboards with only 1 video card and 2 monitors. Unfortunately my work requires the use of 3 monitors so this is a real problem for me. The system below is running with one card in the 3rd PCIe slot, if I add another card to the 1st slot so I can use 3 monitors, the computer will not boot to the desktop. This has been the problem with all 3 of the last motherboards I have recieved in the last 4 weeks. When I am testing these MB's it's with a new Western Digital harddrive with a fresh install of Win 7 pro 64 bit and my i7 950 cpu. I am using the lastest drivers for the video cards from nVidia and the board I am running right now has the lastest bios version from EVGA.
