And only display after cold boot on 2500k, this with the Old amd Card, still no display with gtx970. I am positive now this motherboard just doesnt work right with sandybridge
I have a Z77 Asus board (they all seem to operate similarly), I upgraded from i5 2500K a couple years ago to an i7 3770 (K at the time). First of all, clear the CMOS if you haven't already. I know you stated the firmware was upgrade, but the profiles still stick. It is important to clear the CMOS both when you install a new processor AND upgrade the firmware in these boards.
It could be anything. Perhaps the seller left a high OC mode on and it simply does not POST at the same values. Perhaps he set PCI-E to forced 3.0 instead of auto, and your chip doesn't support 3.0 so... This is just some ideas / theories, clear your cmos!
Also what memory? Sandy is more temperamental then Ivy at certain memory speeds, Sandy really only goes up to 1866Mhz stable in most cases.
