ok guys, just had another 780i just die out of the blue... rebooted after installing updates and the machine is stuck at the first post screen. This is now 3 boards for me in various builds that have kicked the bucket. Mind you now 2 of them were for builds for other people with no overclocking.. mine was.. but it was in spec in terms of overclocking. I went back to my trust maximus formula board and I am currently playing with a 3870x2.
