i have a asrock z97m oc formula. does not boot (no display, no post, no nothing, just fan spins).
i have tried all sorts of method and i think the problem is that the bios not updated to detect my 4790k.
Therefore i need help from someone who have a older processor that is launched in 2013(haswell) instead of 2014(haswell refresh).
So that i can try booting up with it and do a bios update before it is able to boot with haswell refresh processors.

Correct me if i am wrong. Not all z97 boards can detect haswell refresh processors, a bios update may be needed?
