Hi, I have a z87-k with bios version 1402 and an i5-4760. I tried to replace it with a new in-the-box i7-4790 (it says S-spec on the box if that makes a difference). When I tried to boot it there was nothing, no beeps or anything. I put the i5 back in and everything is fine. Did I forget some step when I updated the bios, is the cpu bad, or something else? Thanks for the help.
