HDMI doesn't work after new CPU insert

[gombo4console]

I just got an i5 7600K and I have an Asus H110i I think it's called, I put the cpu in and everything seemed to turn on but the HDMI wasn't working so I put my old CPU in had the same problem, I now know that my motherboard only takes 6th gen max and my new cpu is 7th gen, is it fried now? Because it won't work with either cpu, how do I fix? All pins are fine

Reset CMOS, put your old CPU, boot and update BIOS to version required by 7th gen CPU. What exactly motherboard model you have?

Remove the battery (it is in top left corner of motherboard, just next to HDMI port) for few minutes to reset CMOS. Then you need update BIOS to version 3016.
