Just installed my brand new i5-8400 into my Gigabyte GA-H110M-A and my PC turns on for a second, fans start spinning, and then turns back off. I put my old i3 back in and then updated the BIOS. Still the same outcome. No bent pins, connections are fine.
Any help would be nice. Please PC community, put your bigger brains than the one I have together and help me.
